RFC Abstracts
RFC3986 - Uniform Resource Identifier (URI): Generic Syntax
A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource. This specification defines the generic URI syntax and a process for resolving URI references that might be in relative form, along with guidelines and security considerations for the use of URIs on the Internet. The URI syntax defines a grammar that is a superset of all valid URIs, allowing an implementation to parse the common components of a URI reference without knowing the scheme-specific requirements of every possible identifier. This specification does not define a generative grammar for URIs; that task is performed by the individual specifications of each URI scheme. [STANDARDS-TRACK]

RFC3973 - Protocol Independent Multicast - Dense Mode (PIM-DM): Protocol Specification (Revised)
This document specifies Protocol Independent Multicast - Dense Mode (PIM-DM). PIM-DM is a multicast routing protocol that uses the underlying unicast routing information base to flood multicast datagrams to all multicast routers. Prune messages are used to prevent future messages from propagating to routers without group membership information. This memo defines an Experimental Protocol for the Internet community.
RFC3972 - Cryptographically Generated Addresses (CGA)
This document describes a method for binding a public signature key to an IPv6 address in the Secure Neighbor Discovery (SEND) protocol. Cryptographically Generated Addresses (CGA) are IPv6 addresses for which the interface identifier is generated by computing a cryptographic one-way hash function from a public key and auxiliary parameters. The binding between the public key and the address can be verified by re-computing the hash value and by comparing the hash with the interface identifier. Messages sent from an IPv6 address can be protected by attaching the public key and auxiliary parameters and by signing the message with the corresponding private key. The protection works without a certification authority or any security infrastructure. [STANDARDS-TRACK]
RFC3971 - SEcure Neighbor Discovery (SEND)
IPv6 nodes use the Neighbor Discovery Protocol (NDP) to discover other nodes on the link, to determine their link-layer addresses to find routers, and to maintain reachability information about the paths to active neighbors. If not secured, NDP is vulnerable to various attacks. This document specifies security mechanisms for NDP. Unlike those in the original NDP specifications, these mechanisms do not use IPsec. [STANDARDS-TRACK]
RFC3970 - A Traffic Engineering (TE) MIB

This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3967 - Clarifying when Standards Track Documents may Refer Normatively to Documents at a Lower Level
IETF procedures generally require that a standards track RFC may not have a normative reference to another standards track document at a lower maturity level or to a non standards track specification (other than specifications from other standards bodies). For example, a standards track document may not have a normative reference to an informational RFC. Exceptions to this rule are sometimes needed as the IETF uses informational RFCs to describe non-IETF standards or IETF-specific modes of use of such standards. This document clarifies and updates the procedure used in these circumstances. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3966 - The tel URI for Telephone Numbers
This document specifies the URI (Uniform Resource Identifier) scheme "tel". The "tel" URI describes resources identified by telephone numbers. This document obsoletes RFC 2806. [STANDARDS-TRACK]
RFC3965 - A Simple Mode of Facsimile Using Internet Mail
This specification provides for "simple mode" carriage of facsimile data using Internet mail. Extensions to this document will follow. The current specification employs standard protocols and file formats such as TCP/IP, Internet mail protocols, Multipurpose Internet Mail Extensions (MIME), and Tagged Image File Format (TIFF) for Facsimile. It can send images not only to other Internet-aware facsimile devices but also to Internet-native systems, such as PCs with common email readers which can handle MIME mail and TIFF for Facsimile data. The specification facilitates communication among existing facsimile devices, Internet mail agents, and the gateways which connect them.
RFC3964 - Security Considerations for 6to4
The IPv6 interim mechanism 6to4 (RFC3056) uses automatic IPv6-over-IPv4 tunneling to interconnect IPv6 networks. The architecture includes 6to4 routers and 6to4 relay routers, which accept and decapsulate IPv4 protocol-41 ("IPv6-in-IPv4") traffic from any node in the IPv4 internet. This characteristic enables a number of security threats, mainly Denial of Service. It also makes it easier for nodes to spoof IPv6 addresses. This document discusses these issues in more detail and suggests enhancements to alleviate the problems. This memo provides information for the Internet community.
RFC3963 - Network Mobility (NEMO) Basic Support Protocol
This document describes the Network Mobility (NEMO) Basic Support protocol that enables Mobile Networks to attach to different points in the Internet. The protocol is an extension of Mobile IPv6 and allows session continuity for every node in the Mobile Network as the network moves. It also allows every node in the Mobile Network to be reachable while moving around. The Mobile Router, which connects the network to the Internet, runs the NEMO Basic Support protocol with its Home Agent. The protocol is designed so that network mobility is transparent to the nodes inside the Mobile Network. [STANDARDS-TRACK]
RFC3962 - Advanced Encryption Standard (AES) Encryption for Kerberos 5
The United States National Institute of Standards and Technology (NIST) has chosen a new Advanced Encryption Standard (AES), which is significantly faster and (it is believed) more secure than the old Data Encryption Standard (DES) algorithm. This document is a specification for the addition of this algorithm to the Kerberos cryptosystem suite. [STANDARDS-TRACK]
RFC3961 - Encryption and Checksum Specifications for Kerberos 5
This document describes a framework for defining encryption and checksum mechanisms for use with the Kerberos protocol, defining an abstraction layer between the Kerberos protocol and related protocols, and the actual mechanisms themselves. The document also defines several mechanisms. Some are taken from RFC 1510, modified in form to fit this new framework and occasionally modified in content when the old specification was incorrect. New mechanisms are presented here as well. This document does NOT indicate which mechanisms may be considered "required to implement". [STANDARDS-TRACK]
RFC3960 - Early Media and Ringing Tone Generation in the Session Initiation Protocol (SIP)
This document describes how to manage early media in the Session Initiation Protocol (SIP) using two models: the gateway model and the application server model. It also describes the inputs one needs to consider in defining local policies for ringing tone generation. This memo provides information for the Internet community.
RFC3959 - The Early Session Disposition Type for the Session Initiation Protocol (SIP)
This document defines a new disposition type (early-session) for the Content-Disposition header field in the Session Initiation Protocol (SIP). The treatment of "early-session" bodies is similar to the treatment of "session" bodies. That is, they follow the offer/answer model. Their only difference is that session descriptions whose disposition type is "early-session" are used to establish early media sessions within early dialogs, as opposed to regular sessions within regular dialogs. [STANDARDS-TRACK]
RFC3958 - Domain-Based Application Service Location Using SRV RRs and the Dynamic Delegation Discovery Service (DDDS)
This memo defines a generalized mechanism for application service naming that allows service location without relying on rigid domain naming conventions (so-called name hacks). The proposal defines a Dynamic Delegation Discovery System (DDDS) Application to map domain name, application service name, and application protocol dynamically to target server and port. [STANDARDS-TRACK]
RFC3957 - Authentication, Authorization, and Accounting (AAA) Registration Keys for Mobile IPv4
Authentication, Authorization, and Accounting (AAA) servers, such as RADIUS and DIAMETER, are in use within the Internet today to provide authentication and authorization services for dial-up computers. Mobile IP for IPv4 requires strong authentication between the mobile node and its home agent. When the mobile node shares an AAA Security Association with its home AAA server, however, it is possible to use that AAA Security Association to create derived Mobility Security Associations between the mobile node and its home agent, and again between the mobile node and the foreign agent currently offering connectivity to the mobile node. This document specifies extensions to Mobile IP registration messages that can be used to create Mobility Security Associations between the mobile node and its home agent, and/or between the mobile node and a foreign agent. [STANDARDS-TRACK]
RFC3956 - Embedding the Rendezvous Point (RP) Address in an IPv6 Multicast Address
This memo defines an address allocation policy in which the address of the Rendezvous Point (RP) is encoded in an IPv6 multicast group address. For Protocol Independent Multicast - Sparse Mode (PIM-SM), this can be seen as a specification of a group-to-RP mapping mechanism. This allows an easy deployment of scalable inter-domain multicast and simplifies the intra-domain multicast configuration as well. This memo updates the addressing format presented in RFC 3306. [STANDARDS-TRACK]
RFC3955 - Evaluation of Candidate Protocols for IP Flow Information Export (IPFIX)
This document contains an evaluation of the five candidate protocols for an IP Flow Information Export (IPFIX) protocol, based on the requirements document produced by the IPFIX Working Group. The protocols are characterized and grouped in broad categories, and evaluated against specific requirements. Finally, a recommendation is made to select the NetFlow v9 protocol as the basis for the IPFIX specification. This memo provides information for the Internet community.
RFC3954 - Cisco Systems NetFlow Services Export Version 9
This document specifies the data export format for version 9 of Cisco Systems' NetFlow services, for use by implementations on the network elements and/or matching collector programs. The version 9 export format uses templates to provide access to observations of IP packet flows in a flexible and extensible manner. A template defines a collection of fields, with corresponding descriptions of structure and semantics. This memo provides information for the Internet community.

Also, within the document there are included necessary details for the use of iLBC with MIME and Session Description Protocol (SDP). This memo defines an Experimental Protocol for the Internet community.
RFC3951 - Internet Low Bit Rate Codec (iLBC)
This document specifies a speech codec suitable for robust voice communication over IP. The codec is developed by Global IP Sound (GIPS). It is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s for 20 ms frames. The codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. This memo defines an Experimental Protocol for the Internet community.
RFC3950 - Tag Image File Format Fax eXtended (TIFF-FX) - image/tiff-fx MIME Sub-type Registration
This document describes the registration of the MIME sub-type image/tiff-fx. The encodings are defined by File Format for Internet Fax and its extensions. [STANDARDS-TRACK]
RFC3949 - File Format for Internet Fax
This document is a revised version of RFC 2301. The revisions, summarized in the list attached as Annex B, are based on discussions and suggestions for improvements that have been made since RFC 2301 was issued in March 1998, and on the results of independent implementations and interoperability testing.
RFC3948 - UDP Encapsulation of IPsec ESP Packets
This protocol specification defines methods to encapsulate and decapsulate IP Encapsulating Security Payload (ESP) packets inside UDP packets for traversing Network Address Translators. ESP encapsulation, as defined in this document, can be used in both IPv4 and IPv6 scenarios. Whenever negotiated, encapsulation is used with Internet Key Exchange (IKE). [STANDARDS-TRACK]
RFC3947 - Negotiation of NAT-Traversal in the IKE
This document describes how to detect one or more network address translation devices (NATs) between IPsec hosts, and how to negotiate the use of UDP encapsulation of IPsec packets through NAT boxes in Internet Key Exchange (IKE). [STANDARDS-TRACK]

This document is a companion to the Generalized Multi-Protocol Label Switching (GMPLS) signaling. It defines the Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) technology specific information needed when using GMPLS signaling. [STANDARDS-TRACK]
RFC3945 - Generalized Multi-Protocol Label Switching (GMPLS) Architecture
Future data and transmission networks will consist of elements such as routers, switches, Dense Wavelength Division Multiplexing (DWDM) systems, Add-Drop Multiplexors (ADMs), photonic cross-connects (PXCs), optical cross-connects (OXCs), etc. that will use Generalized Multi-Protocol Label Switching (GMPLS) to dynamically provision resources and to provide network survivability using protection and restoration techniques.
RFC3944 - H.350 Directory Services
The International Telecommunications Union Standardization Sector (ITU-T) has created the H.350 series of Recommendations that specify directory services architectures in support of multimedia conferencing protocols. The goal of the architecture is to 'directory enable' multimedia conferencing so that these services can leverage existing identity management and enterprise directories. A particular goal is to enable an enterprise or service provider to maintain a canonical source of users and their multimedia conferencing systems, so that multiple call servers from multiple vendors, supporting multiple protocols, can all access the same data store. Because SIP is an IETF standard, the contents of H.350 and H.350.4 are made available via this document to the IETF community. This document contains the entire normative text of ITU-T Recommendations H.350 and H.350.4 in sections 4 and 5, respectively. The remaining sections are included only in this document, not in the ITU-T version. This memo provides information for the Internet community.
RFC3943 - Transport Layer Security (TLS) Protocol Compression Using Lempel-Ziv-Stac (LZS)
The Transport Layer Security (TLS) protocol (RFC 2246) includes features to negotiate selection of a lossless data compression method as part of the TLS Handshake Protocol and then to apply the algorithm associated with the selected method as part of the TLS Record Protocol. TLS defines one standard compression method, which specifies that data exchanged via the record protocol will not be compressed. This document describes an additional compression method associated with the Lempel-Ziv-Stac (LZS) lossless data compression algorithm for use with TLS. This document also defines the application of the LZS algorithm to the TLS Record Protocol. This memo provides information for the Internet community.
RFC3942 - Reclassifying Dynamic Host Configuration Protocol version 4 (DHCPv4) Options
This document updates RFC 2132 to reclassify Dynamic Host Configuration Protocol version 4 (DHCPv4) option codes 128 to 223 (decimal) as publicly defined options to be managed by IANA in accordance with RFC 2939. This document directs IANA to make these option codes available for assignment as publicly defined DHCP options for future options. [STANDARDS-TRACK]
RFC3941 - Negative-Acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Building Blocks
This document discusses the creation of negative-acknowledgment (NACK)-oriented reliable multicast (NORM) protocols. The rationale for NORM goals and assumptions are presented. Technical challenges for NACK-oriented (and in some cases general) reliable multicast protocol operation are identified. These goals and challenges are resolved into a set of functional "building blocks" that address different aspects of NORM protocol operation. It is anticipated that these building blocks will be useful in generating different instantiations of reliable multicast protocols. This memo defines an Experimental Protocol for the Internet community.
RFC3940 - Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Protocol
This document describes the messages and procedures of the Negative-acknowledgment (NACK) Oriented Reliable Multicast (NORM) protocol. This protocol is designed to provide end-to-end reliable transport of bulk data objects or streams over generic IP multicast routing and forwarding services. NORM uses a selective, negative acknowledgment mechanism for transport reliability and offers additional protocol mechanisms to allow for operation with minimal "a priori" coordination among senders and receivers. A congestion control scheme is specified to allow the NORM protocol to fairly share available network bandwidth with other transport protocols such as Transmission Control Protocol (TCP). It is capable of operating with both reciprocal multicast routing among senders and receivers and with asymmetric connectivity (possibly a unicast return path) between the senders and receivers. The protocol offers a number of features to allow different types of applications or possibly other higher level transport protocols to utilize its service in different ways. The protocol leverages the use of FEC-based repair and other IETF reliable multicast transport (RMT) building blocks in its design. This memo defines an Experimental Protocol for the Internet community.
RFC3939 - Calling Line Identification for Voice Mail Messages
This document describes a method for identifying the originating calling party in the headers of a stored voice mail message. Two new header fields are defined for this purpose: Caller_ID and Called_Name. Caller_id is used to store sufficient information for the recipient to callback, or reply to, the sender of the message. Caller-name provides the name of the person sending the message. [STANDARDS-TRACK]
RFC3938 - Video-Message Message-Context
The Message-Context header defined in RFC 3458 describes the context of a message (for example: fax-message or voice-message). This specification extends the Message-Context header with one additional context value: "video-message".
RFC3937 - A Uniform Resource Name (URN) Namespace for the International Press Telecommunications Council (IPTC)
This document describes a URN (Uniform Resource Name) namespace for identifying persistent resources published by the International Press Telecommunications Council (IPTC). These resources include XML Data Type Definition files (DTD), XML Schema, Namespaces in XML, XSL stylesheets, other XML based document and documents of other data formats like PDF documents, Microsoft Office documents and others. This memo provides information for the Internet community.

This document creates an Internet Assigned Number Authority (IANA) registry for the Session Initiation Protocol (SIP) and SIPS Uniform Resource Identifier (URI) parameters, and their values. It also lists the already existing parameters to be used as initial values for that registry. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3968 - The Internet Assigned Number Authority (IANA) Header Field Parameter Registry for the Session Initiation Protocol (SIP)
This document creates an Internet Assigned Number Authority (IANA) registry for the Session Initiation Protocol (SIP) header field parameters and parameter values. It also lists the already existing parameters and parameter values to be used as the initial entries for this registry. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3967 - Clarifying when Standards Track Documents may Refer Normatively to Documents at a Lower Level
IETF procedures generally require that a standards track RFC may not have a normative reference to another standards track document at a lower maturity level or to a non standards track specification (other than specifications from other standards bodies). For example, a standards track document may not have a normative reference to an informational RFC. Exceptions to this rule are sometimes needed as the IETF uses informational RFCs to describe non-IETF standards or IETF-specific modes of use of such standards. This document clarifies and updates the procedure used in these circumstances. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3966 - The tel URI for Telephone Numbers
This document specifies the URI (Uniform Resource Identifier) scheme "tel". The "tel" URI describes resources identified by telephone numbers. This document obsoletes RFC 2806. [STANDARDS-TRACK]
RFC3965 - A Simple Mode of Facsimile Using Internet Mail
This specification provides for "simple mode" carriage of facsimile data using Internet mail. Extensions to this document will follow. The current specification employs standard protocols and file formats such as TCP/IP, Internet mail protocols, Multipurpose Internet Mail Extensions (MIME), and Tagged Image File Format (TIFF) for Facsimile. It can send images not only to other Internet-aware facsimile devices but also to Internet-native systems, such as PCs with common email readers which can handle MIME mail and TIFF for Facsimile data. The specification facilitates communication among existing facsimile devices, Internet mail agents, and the gateways which connect them.
RFC3964 - Security Considerations for 6to4
The IPv6 interim mechanism 6to4 (RFC3056) uses automatic IPv6-over-IPv4 tunneling to interconnect IPv6 networks. The architecture includes 6to4 routers and 6to4 relay routers, which accept and decapsulate IPv4 protocol-41 ("IPv6-in-IPv4") traffic from any node in the IPv4 internet. This characteristic enables a number of security threats, mainly Denial of Service. It also makes it easier for nodes to spoof IPv6 addresses. This document discusses these issues in more detail and suggests enhancements to alleviate the problems. This memo provides information for the Internet community.
RFC3963 - Network Mobility (NEMO) Basic Support Protocol
This document describes the Network Mobility (NEMO) Basic Support protocol that enables Mobile Networks to attach to different points in the Internet. The protocol is an extension of Mobile IPv6 and allows session continuity for every node in the Mobile Network as the network moves. It also allows every node in the Mobile Network to be reachable while moving around. The Mobile Router, which connects the network to the Internet, runs the NEMO Basic Support protocol with its Home Agent. The protocol is designed so that network mobility is transparent to the nodes inside the Mobile Network. [STANDARDS-TRACK]
RFC3962 - Advanced Encryption Standard (AES) Encryption for Kerberos 5
The United States National Institute of Standards and Technology (NIST) has chosen a new Advanced Encryption Standard (AES), which is significantly faster and (it is believed) more secure than the old Data Encryption Standard (DES) algorithm. This document is a specification for the addition of this algorithm to the Kerberos cryptosystem suite. [STANDARDS-TRACK]
RFC3961 - Encryption and Checksum Specifications for Kerberos 5
This document describes a framework for defining encryption and checksum mechanisms for use with the Kerberos protocol, defining an abstraction layer between the Kerberos protocol and related protocols, and the actual mechanisms themselves. The document also defines several mechanisms. Some are taken from RFC 1510, modified in form to fit this new framework and occasionally modified in content when the old specification was incorrect. New mechanisms are presented here as well. This document does NOT indicate which mechanisms may be considered "required to implement". [STANDARDS-TRACK]
RFC3960 - Early Media and Ringing Tone Generation in the Session Initiation Protocol (SIP)
This document describes how to manage early media in the Session Initiation Protocol (SIP) using two models: the gateway model and the application server model. It also describes the inputs one needs to consider in defining local policies for ringing tone generation. This memo provides information for the Internet community.
RFC3959 - The Early Session Disposition Type for the Session Initiation Protocol (SIP)
This document defines a new disposition type (early-session) for the Content-Disposition header field in the Session Initiation Protocol (SIP). The treatment of "early-session" bodies is similar to the treatment of "session" bodies. That is, they follow the offer/answer model. Their only difference is that session descriptions whose disposition type is "early-session" are used to establish early media sessions within early dialogs, as opposed to regular sessions within regular dialogs. [STANDARDS-TRACK]
RFC3958 - Domain-Based Application Service Location Using SRV RRs and the Dynamic Delegation Discovery Service (DDDS)
This memo defines a generalized mechanism for application service naming that allows service location without relying on rigid domain naming conventions (so-called name hacks). The proposal defines a Dynamic Delegation Discovery System (DDDS) Application to map domain name, application service name, and application protocol dynamically to target server and port. [STANDARDS-TRACK]
RFC3957 - Authentication, Authorization, and Accounting (AAA) Registration Keys for Mobile IPv4
Authentication, Authorization, and Accounting (AAA) servers, such as RADIUS and DIAMETER, are in use within the Internet today to provide authentication and authorization services for dial-up computers. Mobile IP for IPv4 requires strong authentication between the mobile node and its home agent. When the mobile node shares an AAA Security Association with its home AAA server, however, it is possible to use that AAA Security Association to create derived Mobility Security Associations between the mobile node and its home agent, and again between the mobile node and the foreign agent currently offering connectivity to the mobile node. This document specifies extensions to Mobile IP registration messages that can be used to create Mobility Security Associations between the mobile node and its home agent, and/or between the mobile node and a foreign agent. [STANDARDS-TRACK]
RFC3956 - Embedding the Rendezvous Point (RP) Address in an IPv6 Multicast Address
This memo defines an address allocation policy in which the address of the Rendezvous Point (RP) is encoded in an IPv6 multicast group address. For Protocol Independent Multicast - Sparse Mode (PIM-SM), this can be seen as a specification of a group-to-RP mapping mechanism. This allows an easy deployment of scalable inter-domain multicast and simplifies the intra-domain multicast configuration as well. This memo updates the addressing format presented in RFC 3306. [STANDARDS-TRACK]
RFC3955 - Evaluation of Candidate Protocols for IP Flow Information Export (IPFIX)
This document contains an evaluation of the five candidate protocols for an IP Flow Information Export (IPFIX) protocol, based on the requirements document produced by the IPFIX Working Group. The protocols are characterized and grouped in broad categories, and evaluated against specific requirements. Finally, a recommendation is made to select the NetFlow v9 protocol as the basis for the IPFIX specification. This memo provides information for the Internet community.
RFC3954 - Cisco Systems NetFlow Services Export Version 9
This document specifies the data export format for version 9 of Cisco Systems' NetFlow services, for use by implementations on the network elements and/or matching collector programs. The version 9 export format uses templates to provide access to observations of IP packet flows in a flexible and extensible manner. A template defines a collection of fields, with corresponding descriptions of structure and semantics. This memo provides information for the Internet community.
RFC3953 - Telephone Number Mapping (ENUM) Service Registration for Presence Services
This document registers a Telephone Number Mapping (ENUM) service for presence. Specifically, this document focuses on provisioning pres URIs in ENUM. [STANDARDS-TRACK]
RFC3952 - Real-time Transport Protocol (RTP) Payload Format for internet Low Bit Rate Codec (iLBC) Speech
This document describes the Real-time Transport Protocol (RTP) payload format for the internet Low Bit Rate Codec (iLBC) Speech developed by Global IP Sound (GIPS). Also, within the document there are included necessary details for the use of iLBC with MIME and Session Description Protocol (SDP). This memo defines an Experimental Protocol for the Internet community.
RFC3951 - Internet Low Bit Rate Codec (iLBC)
This document specifies a speech codec suitable for robust voice communication over IP. The codec is developed by Global IP Sound (GIPS). It is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s for 20 ms frames. The codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. This memo defines an Experimental Protocol for the Internet community.
RFC3950 - Tag Image File Format Fax eXtended (TIFF-FX) - image/tiff-fx MIME Sub-type Registration
This document describes the registration of the MIME sub-type image/tiff-fx. The encodings are defined by File Format for Internet Fax and its extensions. [STANDARDS-TRACK]
RFC3949 - File Format for Internet Fax
This document is a revised version of RFC 2301. The revisions, summarized in the list attached as Annex B, are based on discussions and suggestions for improvements that have been made since RFC 2301 was issued in March 1998, and on the results of independent implementations and interoperability testing.
RFC3948 - UDP Encapsulation of IPsec ESP Packets
This protocol specification defines methods to encapsulate and decapsulate IP Encapsulating Security Payload (ESP) packets inside UDP packets for traversing Network Address Translators. ESP encapsulation, as defined in this document, can be used in both IPv4 and IPv6 scenarios. Whenever negotiated, encapsulation is used with Internet Key Exchange (IKE). [STANDARDS-TRACK]
RFC3947 - Negotiation of NAT-Traversal in the IKE
This document describes how to detect one or more network address translation devices (NATs) between IPsec hosts, and how to negotiate the use of UDP encapsulation of IPsec packets through NAT boxes in Internet Key Exchange (IKE). [STANDARDS-TRACK]
RFC3946 - Generalized Multi-Protocol Label Switching (GMPLS) Extensions for Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) Control
This document is a companion to the Generalized Multi-Protocol Label Switching (GMPLS) signaling. It defines the Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) technology specific information needed when using GMPLS signaling. [STANDARDS-TRACK]
RFC3945 - Generalized Multi-Protocol Label Switching (GMPLS) Architecture
Future data and transmission networks will consist of elements such as routers, switches, Dense Wavelength Division Multiplexing (DWDM) systems, Add-Drop Multiplexors (ADMs), photonic cross-connects (PXCs), optical cross-connects (OXCs), etc. that will use Generalized Multi-Protocol Label Switching (GMPLS) to dynamically provision resources and to provide network survivability using protection and restoration techniques.
RFC3944 - H.350 Directory Services
The International Telecommunications Union Standardization Sector (ITU-T) has created the H.350 series of Recommendations that specify directory services architectures in support of multimedia conferencing protocols. The goal of the architecture is to 'directory enable' multimedia conferencing so that these services can leverage existing identity management and enterprise directories. A particular goal is to enable an enterprise or service provider to maintain a canonical source of users and their multimedia conferencing systems, so that multiple call servers from multiple vendors, supporting multiple protocols, can all access the same data store. Because SIP is an IETF standard, the contents of H.350 and H.350.4 are made available via this document to the IETF community. This document contains the entire normative text of ITU-T Recommendations H.350 and H.350.4 in sections 4 and 5, respectively. The remaining sections are included only in this document, not in the ITU-T version. This memo provides information for the Internet community.
RFC3943 - Transport Layer Security (TLS) Protocol Compression Using Lempel-Ziv-Stac (LZS)
The Transport Layer Security (TLS) protocol (RFC 2246) includes features to negotiate selection of a lossless data compression method as part of the TLS Handshake Protocol and then to apply the algorithm associated with the selected method as part of the TLS Record Protocol. TLS defines one standard compression method, which specifies that data exchanged via the record protocol will not be compressed. This document describes an additional compression method associated with the Lempel-Ziv-Stac (LZS) lossless data compression algorithm for use with TLS. This document also defines the application of the LZS algorithm to the TLS Record Protocol. This memo provides information for the Internet community.
RFC3942 - Reclassifying Dynamic Host Configuration Protocol version 4 (DHCPv4) Options
This document updates RFC 2132 to reclassify Dynamic Host Configuration Protocol version 4 (DHCPv4) option codes 128 to 223 (decimal) as publicly defined options to be managed by IANA in accordance with RFC 2939. This document directs IANA to make these option codes available for assignment as publicly defined DHCP options for future options. [STANDARDS-TRACK]
RFC3941 - Negative-Acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Building Blocks
This document discusses the creation of negative-acknowledgment (NACK)-oriented reliable multicast (NORM) protocols. The rationale for NORM goals and assumptions are presented. Technical challenges for NACK-oriented (and in some cases general) reliable multicast protocol operation are identified. These goals and challenges are resolved into a set of functional "building blocks" that address different aspects of NORM protocol operation. It is anticipated that these building blocks will be useful in generating different instantiations of reliable multicast protocols. This memo defines an Experimental Protocol for the Internet community.
RFC3940 - Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Protocol
This document describes the messages and procedures of the Negative-acknowledgment (NACK) Oriented Reliable Multicast (NORM) protocol. This protocol is designed to provide end-to-end reliable transport of bulk data objects or streams over generic IP multicast routing and forwarding services. NORM uses a selective, negative acknowledgment mechanism for transport reliability and offers additional protocol mechanisms to allow for operation with minimal "a priori" coordination among senders and receivers. A congestion control scheme is specified to allow the NORM protocol to fairly share available network bandwidth with other transport protocols such as Transmission Control Protocol (TCP). It is capable of operating with both reciprocal multicast routing among senders and receivers and with asymmetric connectivity (possibly a unicast return path) between the senders and receivers. The protocol offers a number of features to allow different types of applications or possibly other higher level transport protocols to utilize its service in different ways. The protocol leverages the use of FEC-based repair and other IETF reliable multicast transport (RMT) building blocks in its design. This memo defines an Experimental Protocol for the Internet community.
RFC3939 - Calling Line Identification for Voice Mail Messages
This document describes a method for identifying the originating calling party in the headers of a stored voice mail message. Two new header fields are defined for this purpose: Caller_ID and Called_Name. Caller_id is used to store sufficient information for the recipient to callback, or reply to, the sender of the message. Caller-name provides the name of the person sending the message. [STANDARDS-TRACK]
RFC3938 - Video-Message Message-Context
The Message-Context header defined in RFC 3458 describes the context of a message (for example: fax-message or voice-message). This specification extends the Message-Context header with one additional context value: "video-message".
RFC3937 - A Uniform Resource Name (URN) Namespace for the International Press Telecommunications Council (IPTC)
This document describes a URN (Uniform Resource Name) namespace for identifying persistent resources published by the International Press Telecommunications Council (IPTC). These resources include XML Data Type Definition files (DTD), XML Schema, Namespaces in XML, XSL stylesheets, other XML based document and documents of other data formats like PDF documents, Microsoft Office documents and others.
