RFC3678 - Socket Interface Extensions for Multicast Source Filters
The Internet Group Management Protocol (IGMPv3) for IPv4 and the Multicast Listener Discovery (MLDv2) for IPv6 add the capability for applications to express source filters on multicast group memberships, which allows receiver applications to determine the set of senders (sources) from which to accept multicast traffic. This capability also simplifies support of one-to-many type multicast applications. This document specifies new socket options and functions to manage source filters for IP Multicast group memberships. It also defines the socket structures to provide input and output arguments to these new application program interfaces (APIs). These extensions are designed to provide access to the source filtering features, while introducing a minimum of change into the system and providing complete compatibility for existing multicast applications.
RFC3677 - IETF ISOC Board of Trustee Appointment Procedures
This memo outlines the process by which the IETF makes a selection of an Internet Society (ISOC) Board of Trustees appointment.
RFC3676 - The Text/Plain Format and DelSp Parameters
This specification establishes two parameters (Format and DelSP) to be used with the Text/Plain media type. In the presence of these parameters, trailing whitespace is used to indicate flowed lines and a canonical quote indicator is used to indicate quoted lines. This results in an encoding which appears as normal Text/Plain in older implementations, since it is in fact normal Text/Plain, yet provides for superior wrapping/flowing, and quoting. This document supersedes the one specified in RFC 2646, "The Text/Plain Format Parameter", and adds the DelSp parameter to accommodate languages/coded character sets in which ASCII spaces are not used or appear rarely. [STANDARDS-TRACK]
RFC3675 - .sex Considered Dangerous
Periodically there are proposals to mandate the use of a special top level name or an IP address bit to flag "adult" or "unsafe" material or the like. This document explains why this is an ill considered idea from the legal, philosophical, and particularly, the technical points of view.
RFC3674 - Feature Discovery in Lightweight Directory Access Protocol (LDAP)
The Lightweight Directory Access Protocol (LDAP) is an extensible protocol with numerous elective features. This document introduces a general mechanism for discovery of elective features and extensions which cannot be discovered using existing mechanisms.
RFC3673 - Lightweight Directory Access Protocol version 3 (LDAPv3): All Operational Attributes
The Lightweight Directory Access Protocol (LDAP) supports a mechanism for requesting the return of all user attributes but not all operational attributes. This document describes an LDAP extension which clients may use to request the return of all operational attributes.
RFC3672 - Subentries in the Lightweight Directory Access Protocol (LDAP)
In X.500 directories, subentries are special entries used to hold information associated with a subtree or subtree refinement. This document adapts X.500 subentries mechanisms for use with the Lightweight Directory Access Protocol (LDAP).
RFC3671 - Collective Attributes in the Lightweight Directory Access Protocol (LDAP)
X.500 collective attributes allow common characteristics to be shared between collections of entries. This document summarizes the X.500 information model for collective attributes and describes use of collective attributes in LDAP (Lightweight Directory Access Protocol). This document provides schema definitions for collective attributes for use in LDAP.
RFC3670 - Information Model for Describing Network Device QoS Datapath Mechanisms
The purpose of this document is to define an information model to describe the quality of service (QoS) mechanisms inherent in different network devices, including hosts. Broadly speaking, these mechanisms describe the properties common to selecting and conditioning traffic through the forwarding path (datapath) of a network device. This selection and conditioning of traffic in the datapath spans both major QoS architectures: Differentiated Services and Integrated Services. This document should be used with the QoS Policy Information Model (QPIM) to model how policies can be defined to manage and configure the QoS mechanisms (i.e., the classification, marking, metering, dropping, queuing, and scheduling functionality) of devices. Together, these two documents describe how to write QoS policy rules to configure and manage the QoS mechanisms present in the datapaths of devices. This document, as well as QPIM, are information models. That is, they represent information independent of a binding to a specific type of repository
RFC3669 - Guidelines for Working Groups on Intellectual Property Issues
This memo lays out a conceptual framework and rules of thumb useful for working groups dealing with Intellectual Property Rights (IPR) issues. It documents specific examples of how IPR issues have been dealt with in the IETF. This memo provides information for the Internet community.
RFC3668 - Intellectual Property Rights in IETF Technology
The IETF policies about Intellectual Property Rights (IPR), such as patent rights, relative to technologies developed in the IETF are designed to ensure that IETF working groups and participants have as much information about any IPR constraints on a technical proposal as possible. The policies are also intended to benefit the Internet community and the public at large, while respecting the legitimate rights of IPR holders. This memo details the IETF policies concerning IPR related to technology worked on within the IETF. It also describes the objectives that the policies are designed to meet. This memo updates RFC 2026 and, with RFC 3667, replaces Section 10 of RFC 2026. This memo also updates paragraph 4 of Section 3.2 of RFC 2028, for all purposes, including reference [2] in RFC 2418. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3667 - IETF Rights in Contributions
The IETF policies about rights in Contributions to the IETF are designed to ensure that such Contributions can be made available to the IETF and Internet communities while permitting the authors to retain as many rights as possible. This memo details the IETF policies on rights in Contributions to the IETF. It also describes the objectives that the policies are designed to meet. This memo updates RFC 2026, and, with RFC 3668, replaces Section 10 of RFC 2026. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3666 - Session Initiation Protocol (SIP) Public Switched Telephone Network (PSTN) Call Flows
This document contains best current practice examples of Session Initiation Protocol (SIP) call flows showing interworking with the Public Switched Telephone Network (PSTN). Elements in these call flows include SIP User Agents, SIP Proxy Servers, and PSTN Gateways. Scenarios include SIP to PSTN, PSTN to SIP, and PSTN to PSTN via SIP. PSTN telephony protocols are illustrated using ISDN (Integrated Services Digital Network), ISUP (ISDN User Part), and FGB (Feature Group B) circuit associated signaling. PSTN calls are illustrated using global telephone numbers from the PSTN and private extensions served on by a PBX (Private Branch Exchange). Call flow diagrams and message details are shown.
RFC3665 - Session Initiation Protocol (SIP) Basic Call Flow Examples
This document gives examples of Session Initiation Protocol (SIP) call flows. Elements in these call flows include SIP User Agents and Clients, SIP Proxy and Redirect Servers. Scenarios include SIP Registration and SIP session establishment. Call flow diagrams and message details are shown.
RFC3664 - The AES-XCBC-PRF-128 Algorithm for the Internet Key Exchange Protocol (IKE)
Some implementations of IP Security (IPsec) may want to use a pseudo-random function derived from the Advanced Encryption Standard (AES). This document describes such an algorithm, called AES-XCBC-PRF-128.
RFC3663 - Domain Administrative Data in Lightweight Directory Access Protocol (LDAP)
Domain registration data has typically been exposed to the general public via Nicname/Whois for administrative purposes. This document describes the Referral Lightweight Directory Access Protocol (LDAP) Service, an experimental service using LDAP and well-known LDAP types to make domain administrative data available.
RFC3662 - A Lower Effort Per-Domain Behavior (PDB) for Differentiated Services
This document proposes a differentiated services per-domain behavior (PDB) whose traffic may be "starved" (although starvation is not strictly required) in a properly functioning network. This is in contrast to the Internet's "best-effort" or "normal Internet traffic" model, where prolonged starvation indicates network problems. In this sense, the proposed PDB's traffic is forwarded with a "lower" priority than the normal "best-effort" Internet traffic, thus the PDB is called "Lower Effort" (LE). Use of this PDB permits a network operator to strictly limit the effect of its traffic on "best-effort"/"normal" or all other Internet traffic. This document gives some example uses, but does not propose constraining the PDB's use to any particular type of traffic.
RFC3661 - Media Gateway Control Protocol (MGCP) Return Code Usage
This document provides implementation guidelines for the use of return codes in RFC 3435, Media Gateway Control Protocol (MGCP) Version 1.0. Return codes in RFC 3435 do not cover all possible specific situations that may ever occur in a gateway. That is not possible and not necessary. What is important is to ensure that the Call Agent that receives a return code behaves appropriately and consistently for the given situation. The purpose of this document is to provide implementation guidelines to ensure that consistency.
RFC3660 - Basic Media Gateway Control Protocol (MGCP) Packages
This document provides a basic set of Media Gateway Control Protocol (MGCP) packages. The generic, line, trunk, handset, RTP, DTMF (Dual Tone Multifrequency), announcement server and script packages are updates of packages from RFC 2705 with additional explanation and in some cases new versions of these packages. In addition to these, five new packages are defined here. These are the signal list, resource reservation, media format, supplementary services and digit map extension packages.
RFC3659 - Extensions to FTP
This document specifies new FTP commands to obtain listings of remote directories in a defined format, and to permit restarts of interrupted data transfers in STREAM mode. It allows character sets other than US-ASCII, and also defines an optional virtual file storage structure. [STANDARDS-TRACK]
RFC3658 - Delegation Signer (DS) Resource Record (RR)
The delegation signer (DS) resource record (RR) is inserted at a zone cut (i.e., a delegation point) to indicate that the delegated zone is digitally signed and that the delegated zone recognizes the indicated key as a valid zone key for the delegated zone. The DS RR is a modification to the DNS Security Extensions definition, motivated by operational considerations. The intent is to use this resource record as an explicit statement about the delegation, rather than relying on inference. This document defines the DS RR, gives examples of how it is used and describes the implications on resolvers. This change is not backwards compatible with RFC 2535. This document updates RFC 1035, RFC 2535, RFC 3008 and RFC 3090.
RFC3657 - Use of the Camellia Encryption Algorithm in Cryptographic Message Syntax (CMS)
This document specifies the conventions for using the Camellia encryption algorithm for encryption with the Cryptographic Message Syntax (CMS).
RFC3656 - The Mailbox Update (MUPDATE) Distributed Mailbox Database Protocol
As the demand for high-performance mail delivery agents increases, it becomes apparent that single-machine solutions are inadequate to the task, both because of capacity limits and that the failure of the single machine means a loss of mail delivery for all users. It is preferable to allow many machines to share the responsibility of mail delivery. The Mailbox Update (MUPDATE) protocol allows a group of Internet Message Access Protocol (IMAP) or Post Office Protocol - Version 3 (POP3) servers to function with a unified mailbox namespace. This document is intended to serve as a reference guide to that protocol.
RFC3655 - Redefinition of DNS Authenticated Data (AD) bit
This document alters the specification defined in RFC 2535. Based on implementation experience, the Authenticated Data (AD) bit in the DNS header is not useful. This document redefines the AD bit such that it is only set if all answers or records proving that no answers exist in the response has been cryptographically verified or otherwise meets the server's local security policy.
RFC3654 - Requirements for Separation of IP Control and Forwarding
This document introduces the Forwarding and Control Element Separation (ForCES) architecture and defines a set of associated terminology. This document also defines a set of architectural, modeling, and protocol requirements to logically separate the control and data forwarding planes of an IP (IPv4, IPv6, etc.) networking device.
RFC3653 - XML-Signature XPath Filter 2.0
XML Signature recommends a standard means for specifying information content to be digitally signed and for representing the resulting digital signatures in XML. Some applications require the ability to specify a subset of a given XML document as the information content to be signed. The XML Signature specification meets this requirement with the XPath transform. However, this transform can be difficult to implement efficiently with existing technologies. This specification defines a new XML Signature transform to facilitate the development of efficient document subsetting implementations that interoperate under similar performance profiles. This document is the W3C XML Signature XPath-Filter 2.0 Recommendation. This document has been reviewed by W3C Members and other interested parties and has been endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited as a normative reference from another document. W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability of the Web.
RFC3652 - Handle System Protocol (ver 2.1) Specification
The Handle System is a general-purpose global name service that allows secured name resolution and administration over the public Internet. This document describes the protocol used for client software to access the Handle System for both handle resolution and administration. The protocol specifies the procedure for a client software to locate the responsible handle server of any given handle. It also defines the messages exchanged between the client and server for any handle operation.
RFC3651 - Handle System Namespace and Service Definition
The Handle System is a general-purpose global name service that allows secured name resolution and administration over the public Internet. This document provides a detailed description of the Handle System namespace, and its data, service, and operation models. The namespace definition specifies the handle syntax and its semantic structure. The data model defines the data structures used by the Handle System protocol and any pre-defined data types for carrying out the handle service. The service model provides definitions of various Handle System components and explains how they work together over the network. Finally, the Handle System operation model describes its service operation in terms of messages transmitted between client and server, and the client authentication process based on the Handle System authentication protocol.
RFC3650 - Handle System Overview
This document provides an overview of the Handle System in terms of its namespace and service architecture, as well as its relationship to other Internet services such as DNS, LDAP/X.500, and URNs. The Handle System is a general-purpose global name service that allows secured name resolution and administration over networks such as the Internet. The Handle System manages handles, which are unique names for digital objects and other Internet resources.
RFC3649 - HighSpeed TCP for Large Congestion Windows
The proposals in this document are experimental. While they may be deployed in the current Internet, they do not represent a consensus that this is the best method for high-speed congestion control. In particular, we note that alternative experimental proposals are likely to be forthcoming, and it is not well understood how the proposals in this document will interact with such alternative proposals. This document proposes HighSpeed TCP, a modification to TCP's congestion control mechanism for use with TCP connections with large congestion windows. The congestion control mechanisms of the current Standard TCP constrains the congestion windows that can be achieved by TCP in realistic environments. For example, for a Standard TCP connection with 1500-byte packets and a 100 ms round-trip time, achieving a steady-state throughput of 10 Gbps would require an average congestion window of 83,333 segments, and a packet drop rate of at most one congestion event every 5,000,000,000 packets (or equivalently, at most one congestion event every 1 2/3 hours). This is widely acknowledged as an unrealistic constraint. To address his limitation of TCP, this document proposes HighSpeed TCP, and solicits experimentation and feedback from the wider community.
RFC3648 - Web Distributed Authoring and Versioning (WebDAV) Ordered Collections Protocol
This specification extends the Web Distributed Authoring and Versioning (WebDAV) Protocol to support the server-side ordering of collection members. Of particular interest are orderings that are not based on property values, and so cannot be achieved using a search protocol's ordering option and cannot be maintained automatically by the server. Protocol elements are defined to let clients specify the position in the ordering of each collection member, as well as the semantics governing the ordering.
RFC3647 - Internet X.509 Public Key Infrastructure Certificate Policy and Certification Practices Framework
This document presents a framework to assist the writers of certificate policies or certification practice statements for participants within public key infrastructures, such as certification authorities, policy authorities, and communities of interest that wish to rely on certificates. In particular, the framework provides a comprehensive list of topics that potentially (at the writer's discretion) need to be covered in a certificate policy or a certification practice statement. This document supersedes RFC 2527.
RFC3646 - DNS Configuration options for Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
This document describes Dynamic Host Configuration Protocol for IPv6 (DHCPv6) options for passing a list of available DNS recursive name servers and a domain search list to a client.
RFC3645 - Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS (GSS-TSIG)
The Secret Key Transaction Authentication for DNS (TSIG) protocol provides transaction level authentication for DNS. TSIG is extensible through the definition of new algorithms. This document specifies an algorithm based on the Generic Security Service Application Program Interface (GSS-API) (RFC2743). This document updates RFC 2845.
RFC3644 - Policy Quality of Service (QoS) Information Model
This document presents an object-oriented information model for representing Quality of Service (QoS) network management policies. This document is based on the IETF Policy Core Information Model and its extensions. It defines an information model for QoS enforcement for differentiated and integrated services using policy. It is important to note that this document defines an information model, which by definition is independent of any particular data storage mechanism and access protocol.
RFC3643 - Fibre Channel (FC) Frame Encapsulation
This document describes the common Fibre Channel (FC) frame encapsulation format and a procedure for the measurement and calculation of frame transit time through the IP network. This specification is intended for use by any IETF protocol that encapsulates FC frames.
RFC3642 - Common Elements of Generic String Encoding Rules (GSER) Encodings
The Generic String Encoding Rules (GSER) describe a human readable text encoding for an Abstract Syntax Notation One (ASN.1) value of any ASN.1 type. Specifications making use of GSER may wish to provide an equivalent Augmented Backus-Naur Form (ABNF) description of the GSER encoding for a particular ASN.1 type as a convenience for implementors. This document supports such specifications by providing equivalent ABNF for the GSER encodings for ASN.1 types that commonly occur in Lightweight Directory Access Protocol (LDAP) syntaxes.
RFC3641 - Generic String Encoding Rules (GSER) for ASN.1 Types
This document defines a set of Abstract Syntax Notation One (ASN.1) encoding rules, called the Generic String Encoding Rules (GSER), that produce a human readable text encoding for values of any given ASN.1 data type.
RFC3640 - RTP Payload Format for Transport of MPEG-4 Elementary Streams
The Motion Picture Experts Group (MPEG) Committee (ISO/IEC JTC1/SC29 WG11) is a working group in ISO that produced the MPEG-4 standard. MPEG defines tools to compress content such as audio-visual information into elementary streams. This specification defines a simple, but generic RTP payload format for transport of any non-multiplexed MPEG-4 elementary stream.
RFC3639 - Considerations on the use of a Service Identifier in Packet Headers
This memo describes some considerations relating to the use of IP protocol number fields and payload protocol (e.g., TCP) port fields to identify particular services that may be associated with that port number or protocol number.
RFC3638 - Applicability Statement for Reclassification of RFC 1643 to Historic Status
This memo recommends that RFC 1643 be reclassified as an Historic document and provides the supporting motivation for that recommendation.
RFC3637 - Definitions of Managed Objects for the Ethernet WAN Interface Sublayer
This document defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP based internets. In particular, it defines objects for managing the Ethernet Wide Area Network (WAN) Interface Sublayer (WIS). The MIB module defined in this memo is an extension of the Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Interface MIB and is implemented in conjunction with it and with the Ethernet-like Interface MIB, the 802.3 Medium Attachment Unit MIB, the Interfaces Group MIB, and the Inverted Stack Table MIB.
RFC3636 - Definitions of Managed Objects for IEEE 802.3 Medium Attachment Units (MAUs)
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for managing IEEE 802.3 Medium Attachment Units (MAUs). This memo obsoletes RFC 2668. This memo extends that specification by including management information useful for the management of 10 gigabit per second (Gb/s) MAUs. This memo also obsoletes RFC 1515.
RFC3635 - Definitions of Managed Objects for the Ethernet-like Interface Types
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for managing Ethernet-like interfaces. This memo obsoletes RFC 2665. It updates that specification by including management information useful for the management of 10 Gigabit per second (Gb/s) Ethernet interfaces.
RFC3634 - Key Distribution Center (KDC) Server Address Sub-option for the Dynamic Host Configuration Protocol (DHCP) CableLabs Client Configuration (CCC) Option
This document defines a new sub-option for the CableLabs Client Configuration (CCC) Dynamic Host Configuration Protocol (DHCP) option code for conveying the network addresses of Key Distribution Center (KDC) servers.
RFC3633 - IPv6 Prefix Options for Dynamic Host Configuration Protocol (DHCP) version 6
The Prefix Delegation options provide a mechanism for automated delegation of IPv6 prefixes using the Dynamic Host Configuration Protocol (DHCP). This mechanism is intended for delegating a long-lived prefix from a delegating router to a requesting router, across an administrative boundary, where the delegating router does not require knowledge about the topology of the links in the network to which the prefixes will be assigned.
RFC3632 - VeriSign Registry Registrar Protocol (RRP) Version 2.0.0
This document updates version 1.1.0 of the Network Solutions Inc. (NSI) Registry Registrar Protocol (RRP) specified in RFC 2832. The changes described in this document combined with the base specification documented in RFC 2832 specify version 2.0.0 of the VeriSign Registry Registrar Protocol.
RFC3631 - Security Mechanisms for the Internet
Security must be built into Internet Protocols for those protocols to offer their services securely. Many security problems can be traced to improper implementations. However, even a proper implementation will have security problems if the fundamental protocol is itself exploitable. Exactly how security should be implemented in a protocol will vary, because of the structure of the protocol itself. However, there are many protocols for which standard Internet security mechanisms, already developed, may be applicable. The precise one that is appropriate in any given situation can vary. We review a number of different choices, explaining the properties of each.
RFC3630 - Traffic Engineering (TE) Extensions to OSPF Version 2
This document describes extensions to the OSPF protocol version 2 to support intra-area Traffic Engineering (TE), using Opaque Link State Advertisements.
RFC3629 - UTF-8, a transformation format of ISO 10646
ISO/IEC 10646-1 defines a large character set called the Universal Character Set (UCS) which encompasses most of the world's writing systems. The originally proposed encodings of the UCS, however, were not compatible with many current applications and protocols, and this has led to the development of UTF-8, the object of this memo. UTF-8 has the characteristic of preserving the full US-ASCII range, providing compatibility with file systems, parsers and other software that rely on US-ASCII values but are transparent to other values. This memo obsoletes and replaces RFC 2279.
