RFC4413 - TCP/IP Field Behavior
This memo describes TCP/IP field behavior in the context of header compression. Header compression is possible because most header fields do not vary randomly from packet to packet. Many of the fields exhibit static behavior or change in a more or less predictable way. When a header compression scheme is designed, it is of fundamental importance to understand the behavior of the fields in detail. An example of this analysis can be seen in RFC 3095. This memo performs a similar role for the compression of TCP/IP headers. This memo provides information for the Internet community.
RFC4412 - Communications Resource Priority for the Session Initiation Protocol (SIP)
This document defines two new Session Initiation Protocol (SIP) header fields for communicating resource priority, namely, "Resource-Priority" and "Accept-Resource-Priority". The "Resource-Priority" header field can influence the behavior of SIP user agents (such as telephone gateways and IP telephones) and SIP proxies. It does not directly influence the forwarding behavior of IP routers. [STANDARDS-TRACK]
RFC4411 - Extending the Session Initiation Protocol (SIP) Reason Header for Preemption Events
This document proposes an IANA Registration extension to the Session Initiation Protocol (SIP) Reason Header to be included in a BYE Method Request as a result of a session preemption event, either at a user agent (UA), or somewhere in the network involving a reservation-based protocol such as the Resource ReSerVation Protocol (RSVP) or Next Steps in Signaling (NSIS). This document does not attempt to address routers failing in the packet path; instead, it addresses a deliberate tear down of a flow between UAs, and informs the terminated UA(s) with an indication of what occurred. [STANDARDS-TRACK]
RFC4410 - Selectively Reliable Multicast Protocol (SRMP)
The Selectively Reliable Multicast Protocol (SRMP) is a transport protocol, intended to deliver a mix of reliable and best-effort messages in an any-to-any multicast environment, where the best-effort traffic occurs in significantly greater volume than the reliable traffic and therefore can carry sequence numbers of reliable messages for loss detection. SRMP is intended for use in a distributed simulation application environment, where only the latest value of reliable transmission for any particular data identifier requires delivery. SRMP has two sublayers: a bundling sublayer handling message aggregation and congestion control, and a Selectively Reliable Transport (SRT) sublayer. Selection between reliable and best-effort messages is performed by the application. This memo defines an Experimental Protocol for the Internet community.
RFC4409 - Message Submission for Mail
This memo splits message submission from message relay, allowing each service to operate according to its own rules (for security, policy, etc.), and specifies what actions are to be taken by a submission server.
RFC4408 - Sender Policy Framework (SPF) for Authorizing Use of Domains in E-Mail, Version 1
E-mail on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the reverse-path of a message or the domain given on the SMTP HELO/EHLO commands. This document describes version 1 of the ender Policy Framework (SPF) protocol, whereby a domain may explicitly authorize the hosts that are allowed to use its domain name, and a receiving host may check such authorization. This memo defines an Experimental Protocol for the Internet community.
RFC4407 - Purported Responsible Address in E-Mail Messages
This document defines an algorithm by which, given an e-mail message, one can extract the identity of the party that appears to have most proximately caused that message to be delivered. This identity is called the Purported Responsible Address (PRA).This memo defines an Experimental Protocol for the Internet community.
RFC4406 - Sender ID: Authenticating E-Mail
Internet mail suffers from the fact that much unwanted mail is sent using spoofed addresses -- "spoofed" in this case means that the address is used without the permission of the domain owner. This document describes a family of tests by which SMTP servers can determine whether an e-mail address in a received message was used with the permission of the owner of the domain contained in that e-mail address. This memo defines an Experimental Protocol for the Internet community.
RFC4405 - SMTP Service Extension for Indicating the Responsible Submitter of an E-Mail Message
This memo defines an extension to the Simple Mail Transfer Protocol (SMTP) service that allows an SMTP client to specify the responsible submitter of an e-mail message. The responsible submitter is the e-mail address of the entity most recently responsible for introducing a message into the transport stream. This extension helps receiving e-mail servers efficiently determine whether the SMTP client is authorized to transmit mail on behalf of the responsible submitter's domain. This memo defines an Experimental Protocol for the Internet community.
RFC4404 - Definitions of Managed Objects for Fibre Channel Over TCP/IP (FCIP)

[STANDARDS-TRACK]
RFC4401 - A Pseudo-Random Function (PRF) API Extension for the Generic Security Service Application Program Interface (GSS-API)
This document defines a Pseudo-Random Function (PRF) extension to the Generic Security Service Application Program Interface (GSS-API) for keying application protocols given an established GSS-API security context. The primary intended use of this function is to key secure session layers that do not or cannot use GSS-API per-message message integrity check (MIC) and wrap tokens for session protection. [STANDARDS-TRACK]
RFC4398 - Storing Certificates in the Domain Name System (DNS)
Cryptographic public keys are frequently published, and their authenticity is demonstrated by certificates. A CERT resource record (RR) is defined so that such certificates and related certificate revocation lists can be stored in the Domain Name System (DNS). [STANDARDS-TRACK]
RFC4397 - A Lexicography for the Interpretation of Generalized Multiprotocol Label Switching (GMPLS) Terminology within the Context of the ITU-T's Automatically Switched Optical Network (ASON) Architecture
Generalized Multiprotocol Label Switching (GMPLS) has been developed by the IETF to facilitate the establishment of Label Switched Paths (LSPs) in a variety of data plane technologies and across several architectural models. The ITU-T has specified an architecture for the control of Automatically Switched Optical Networks (ASON).
RFC4396 - RTP Payload Format for 3rd Generation Partnership Project (3GPP) Timed Text
This document specifies an RTP payload format for the transmission of 3GPP (3rd Generation Partnership Project) timed text. 3GPP timed text is a time-lined, decorated text media format with defined storage in a 3GP file.

RFC4394 - A Transport Network View of the Link Management Protocol (LMP)
The Link Management Protocol (LMP) has been developed as part of the Generalized MPLS (GMPLS) protocol suite to manage Traffic Engineering (TE) resources and links. The GMPLS control plane (routing and signaling) uses TE links for establishing Label Switched Paths (LSPs). This memo describes the relationship of the LMP procedures to 'discovery' as defined in the International Telecommunication Union (ITU-T), and ongoing ITU-T work. This document provides an overview of LMP in the context of the ITU-T Automatically Switched Optical Networks (ASON) and transport network terminology and relates it to the ITU-T discovery work to promote a common understanding for progressing the work of IETF and ITU-T. This memo provides information for the Internet community.
RFC4393 - MIME Type Registrations for 3GPP2 Multimedia Files
This document serves to register and document the standard MIME types associated with the 3GPP2 multimedia file format, which is part of the family based on the ISO Media File Format. [STANDARDS-TRACK]
RFC4392 - IP over InfiniBand (IPoIB) Architecture
InfiniBand is a high-speed, channel-based interconnect between systems and devices.
RFC4391 - Transmission of IP over InfiniBand (IPoIB)
This document specifies a method for encapsulating and transmitting IPv4/IPv6 and Address Resolution Protocol (ARP) packets over InfiniBand (IB). It describes the link-layer address to be used when resolving the IP addresses in IP over InfiniBand (IPoIB) subnets. The document also describes the mapping from IP multicast addresses to InfiniBand multicast addresses. In addition, this document defines the setup and configuration of IPoIB links. [STANDARDS-TRACK]
RFC4390 - Dynamic Host Configuration Protocol (DHCP) over InfiniBand
IP over Infiniband (IPoIB) link-layer address is 20 octets long. This is larger than the 16 octets reserved for the hardware address in a Dynamic Host Configuration Protocol/Bootstrap Protocol (DHCP/BOOTP) message. The above inequality imposes restrictions on the use of the DHCP message fields when used over an IPoIB network. This document describes the use of DHCP message fields when implementing DHCP over IPoIB. [STANDARDS-TRACK]
RFC4389 - Neighbor Discovery Proxies (ND Proxy)
Bridging multiple links into a single entity has several operational advantages. A single subnet prefix is sufficient to support multiple physical links. There is no need to allocate subnet numbers to the different networks, simplifying management. Bridging some types of media requires network-layer support, however. This document describes these cases and specifies the IP-layer support that enables bridging under these circumstances. This memo defines an Experimental Protocol for the Internet community.
RFC4388 - Dynamic Host Configuration Protocol (DHCP) Leasequery
A Dynamic Host Configuration Protocol version 4 (DHCPv4) server is the authoritative source of IP addresses that it has provided to DHCPv4 clients. Other processes and devices that already make use of DHCPv4 may need to access this information. The leasequery protocol provides these processes and devices a lightweight way to access IP address information. [STANDARDS-TRACK]
RFC4387 - Internet X.509 Public Key Infrastructure Operational Protocols: Certificate Store Access via HTTP
The protocol conventions described in this document satisfy some of the operational requirements of the Internet Public Key Infrastructure (PKI). This document specifies the conventions for using the Hypertext Transfer Protocol (HTTP/HTTPS) as an interface mechanism to obtain certificates and certificate revocation lists (CRLs) from PKI repositories. Additional mechanisms addressing PKIX operational requirements are specified in separate documents. [STANDARDS-TRACK]
RFC4386 - Internet X.509 Public Key Infrastructure Repository Locator Service

The service enables certificate-using systems to locate PKI repositories.This memo defines an Experimental Protocol for the Internet community.
RFC4385 - Pseudowire Emulation Edge-to-Edge (PWE3) Control Word for Use over an MPLS PSN
This document describes the preferred design of a Pseudowire Emulation Edge-to-Edge (PWE3) Control Word to be used over an MPLS packet switched network, and the Pseudowire Associated Channel Header. The design of these fields is chosen so that an MPLS Label Switching Router performing MPLS payload inspection will not confuse a PWE3 payload with an IP payload. [STANDARDS-TRACK]
RFC4384 - BGP Communities for Data Collection
BGP communities (RFC 1997) are used by service providers for many purposes, including tagging of customer, peer, and geographically originated routes. Such tagging is typically used to control the scope of redistribution of routes within a provider's network and to its peers and customers. With the advent of large-scale BGP data collection (and associated research), it has become clear that the information carried in such communities is essential for a deeper understanding of the global routing system. This memo defines standard (outbound) communities and their encodings for export to BGP route collectors. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC4383 - The Use of Timed Efficient Stream Loss-Tolerant Authentication (TESLA) in the Secure Real-time Transport Protocol (SRTP)

[STANDARDS-TRACK]
RFC4381 - Analysis of the Security of BGP/MPLS IP Virtual Private Networks (VPNs)
This document analyses the security of the BGP/MPLS IP virtual private network (VPN) architecture that is described in RFC 4364, for the benefit of service providers and VPN users.
RFC4380 - Teredo: Tunneling IPv6 over UDP through Network Address Translations (NATs)
We propose here a service that enables nodes located behind one or more IPv4 Network Address Translations (NATs) to obtain IPv6 connectivity by tunneling packets over UDP; we call this the Teredo service. Running the service requires the help of "Teredo servers" and "Teredo relays". The Teredo servers are stateless, and only have to manage a small fraction of the traffic between Teredo clients; the Teredo relays act as IPv6 routers between the Teredo service and the "native" IPv6 Internet. The relays can also provide interoperability with hosts using other transition mechanisms such as "6to4". [STANDARDS-TRACK]
RFC4379 - Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures
This document describes a simple and efficient mechanism that can be used to detect data plane failures in Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs). There are two parts to this document: information carried in an MPLS "echo request" and "echo reply" for the purposes of fault detection and isolation, and mechanisms for reliably sending the echo reply. [STANDARDS-TRACK]
RFC4378 - A Framework for Multi-Protocol Label Switching (MPLS) Operations and Management (OAM)
This document is a framework for how data plane protocols can be applied to operations and maintenance procedures for Multi-Protocol Label Switching (MPLS).

RFC4373 - Lightweight Directory Access Protocol (LDAP) Bulk Update/Replication Protocol (LBURP)
The Lightweight Directory Access Protocol (LDAP) Bulk Update/Replication Protocol (LBURP) allows an LDAP client to perform a bulk update to an LDAP server. The protocol frames a sequenced set of update operations within a pair of LDAP extended operations to notify the server that the update operations in the framed set are related in such a way that the ordering of all operations can be preserved during processing even when they are sent asynchronously by the client. Update operations can be grouped within a single protocol message to maximize the efficiency of client-server communication.
RFC4372 - Chargeable User Identity
This document describes a new Remote Authentication Dial-In User Service (RADIUS) attribute, Chargeable-User-Identity. This attribute can be used by a home network to identify a user for the purpose of roaming transactions that occur outside of the home network. [STANDARDS-TRACK]
RFC4371 - BCP 101 Update for IPR Trust
This document updates BCP 101 to take account of the new IETF Intellectual Property Trust. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC4370 - Lightweight Directory Access Protocol (LDAP) Proxied Authorization Control
This document defines the Lightweight Directory Access Protocol (LDAP) Proxy Authorization Control. The Proxy Authorization Control allows a client to request that an operation be processed under a provided authorization identity instead of under the current authorization identity associated with the connection. [STANDARDS-TRACK]
RFC4369 - Definitions of Managed Objects for Internet Fibre Channel Protocol (iFCP)
The iFCP protocol (RFC 4172) provides Fibre Channel fabric functionality on an IP network in which TCP/IP switching and routing elements replace Fibre Channel components. The iFCP protocol is used between iFCP Gateways. This document provides a mechanism to monitor and control iFCP Gateway instances, and their associated sessions, using SNMP. [STANDARDS-TRACK]
RFC4368 - Multiprotocol Label Switching (MPLS) Label-Controlled Asynchronous Transfer Mode (ATM) and Frame-Relay Management Interface Definition
This memo defines two MIB modules and corresponding MIB Object Definitions that describe how label-switching-controlled Frame-Relay and Asynchronous Transfer Mode (ATM) interfaces can be managed given the interface stacking as defined in the MPLS-LSR-STD-MIB and MPLS-TE-STD-MIB. [STANDARDS-TRACK]
RFC4367 - What's in a Name: False Assumptions about DNS Names
The Domain Name System (DNS) provides an essential service on the Internet, mapping structured names to a variety of data, usually IP addresses. These names appear in email addresses, Uniform Resource Identifiers (URIs), and other application-layer identifiers that are often rendered to human users. Because of this, there has been a strong demand to acquire names that have significance to people, through equivalence to registered trademarks, company names, types of services, and so on. There is a danger in this trend; the humans and automata that consume and use such names will associate specific semantics with some names and thereby make assumptions about the services that are, or should be, provided by the hosts associated with the names. Those assumptions can often be false, resulting in a variety of failure conditions. This document discusses this problem in more detail and makes recommendations on how it can be avoided. This memo provides information for the Internet community.
RFC4366 - Transport Layer Security (TLS) Extensions
This document describes extensions that may be used to add functionality to Transport Layer Security (TLS). It provides both generic extension mechanisms for the TLS handshake client and server hellos, and specific extensions using these generic mechanisms.
RFC4365 - Applicability Statement for BGP/MPLS IP Virtual Private Networks (VPNs)
This document provides an Applicability Statement for the Virtual Private Network (VPN) solution described in RFC 4364 and other documents listed in the References section. This memo provides information for the Internet community.
RFC4364 - BGP/MPLS IP Virtual Private Networks (VPNs)
This document describes a method by which a Service Provider may use an IP backbone to provide IP Virtual Private Networks (VPNs) for its customers. This method uses a "peer model", in which the customers' edge routers (CE routers) send their routes to the Service Provider's edge routers (PE routers); there is no "overlay" visible to the customer's routing algorithm, and CE routers at different sites do not peer with each other. Data packets are tunneled through the backbone, so that the core routers do not need to know the VPN routes. [STANDARDS-TRACK]
RFC4363 - Definitions of Managed Objects for Bridges with Traffic Classes, Multicast Filtering, and Virtual LAN Extensions
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines two MIB modules for managing the capabilities of MAC bridges defined by the IEEE 802.1D-1998 (TM) MAC Bridges and the IEEE 802.1Q-2003 (TM) Virtual LAN (VLAN) standards for bridging between Local Area Network (LAN) segments. One MIB module defines objects for managing the 'Traffic Classes' and 'Enhanced Multicast Filtering' components of IEEE 802.1D-1998 and P802.1t-2001 (TM). The other MIB module defines objects for managing VLANs, as specified in IEEE 802.1Q-2003, P802.1u (TM), and P802.1v (TM).
RFC4362 - RObust Header Compression (ROHC): A Link-Layer Assisted Profile for IP/UDP/RTP
This document defines a ROHC (Robust Header Compression) profile for compression of IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) packets, utilizing functionality provided by the lower layers to increase compression efficiency by completely eliminating the header for most packets during optimal operation. The profile is built as an extension to the ROHC RTP profile. It defines additional mechanisms needed in ROHC, states requirements on the assisting layer to guarantee transparency, and specifies general logic for compression and decompression related to the usage of the header-free packet format. This document is a replacement for RFC 3242, which it obsoletes. [STANDARDS-TRACK]
