RFC3916 - Requirements for Pseudo-Wire Emulation Edge-to-Edge (PWE3)

This document describes base requirements for the Pseudo-Wire Emulation Edge to Edge Working Group (PWE3 WG). It provides guidelines for other working group documents that will define mechanisms for providing pseudo-wire emulation of Ethernet, ATM, and Frame Relay. Requirements for pseudo-wire emulation of TDM (i.e., "synchronous bit streams at rates defined by ITU G.702") are defined in another document. It should be noted that the PWE3 WG standardizes mechanisms that can be used to provide PWE3 services, but not the services themselves. This memo provides information for the Internet community.

RFC4447 - Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)

Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, and Ethernet) can be "emulated" over an MPLS backbone by encapsulating the Layer 2 Protocol Data Units (PDU) and transmitting them over "pseudowires". It is also possible to use pseudowires to provide low-rate Time Division Multiplexed and a Synchronous Optical NETworking circuit emulation over an MPLS-enabled network. This document specifies a protocol for establishing and maintaining the pseudowires, using extensions to Label Distribution Protocol (LDP). Procedures for encapsulating Layer 2 PDUs are specified in a set of companion documents. [STANDARDS-TRACK]

RFC4863 - Wildcard Pseudowire Type

Pseudowire signaling requires that the Pseudowire Type (PW Type) be identical in both directions. For certain applications the configuration of the PW Type is most easily accomplished by configuring this information at just one PW endpoint. In any form of LDP-based signaling, each PW endpoint must initiate the creation of a unidirectional LSP. In order to allow the initiation of these two LSPs to remain independent, a means is needed for allowing the PW endpoint (lacking a priori knowledge of the PW Type) to initiate the creation of an LSP. This document defines a Wildcard PW Type to satisfy this need. [STANDARDS-TRACK]

RFC5003 - Attachment Individual Identifier (AII) Types for Aggregation

The signaling protocols used to establish point-to-point pseudowires include type-length-value (TLV) fields that identify pseudowire endpoints called attachment individual identifiers (AIIs). This document defines AII structures in the form of new AII TLV fields that support AII aggregation for improved scalability and Virtual Private Network (VPN) auto-discovery. It is envisioned that this would be useful in large inter-domain virtual private wire service networks where pseudowires are established between selected local and remote provider edge (PE) nodes based on customer need. [STANDARDS-TRACK]

VCCV applies to all supported access circuit and transport types currently defined for PWs. [STANDARDS-TRACK]

RFC5086 - Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation Service over Packet Switched Network (CESoPSN)

This document describes a method for encapsulating structured (NxDS0) Time Division Multiplexed (TDM) signals as pseudowires over packet-switching networks (PSNs). In this regard, it complements similar work for structure-agnostic emulation of TDM bit-streams (see RFC 4553). This memo provides information for the Internet community.

RFC5087 - Time Division Multiplexing over IP (TDMoIP)

Time Division Multiplexing over IP (TDMoIP) is a structure-aware method for transporting Time Division Multiplexed (TDM) signals using pseudowires (PWs). Being structure-aware, TDMoIP is able to ensure TDM structure integrity, and thus withstand network degradations better than structure-agnostic transport. Structure-aware methods can distinguish individual channels, enabling packet loss concealment and bandwidth conservation. Accessibility of TDM signaling facilitates mechanisms that exploit or manipulate signaling. This memo provides information for the Internet community.

RFC5254 - Requirements for Multi-Segment Pseudowire Emulation Edge-to-Edge (PWE3)

This document describes an architecture for extending pseudowire emulation across multiple packet switched network (PSN) segments. Scenarios are discussed where each segment of a given edge-to-edge emulated service spans a different provider's PSN, as are other scenarios where the emulated service originates and terminates on the same provider's PSN, but may pass through several PSN tunnel segments in that PSN. It presents an architectural framework for such multi-segment pseudowires, defines terminology, and specifies the various protocol elements and their functions. This memo provides information for the Internet community.

RFC5994 - Application of Ethernet Pseudowires to MPLS Transport Networks

Ethernet pseudowires are widely deployed to support packet transport of Ethernet services. These services in-turn provide transport for a variety of client networks, e.g., IP and MPLS. This document uses procedures defined in the existing IETF specifications of Ethernet pseudowires carried over MPLS networks.

Many of the requirements for the services provided by the mechanisms explained in this document are also recognized by the MPLS transport profile (MPLS-TP) design effort formed jointly by the IETF and ITU-T. The solution described here does not address all of the MPLS-TP requirements, but it provides a viable form of packet transport service using tools that are already available.

This document also serves as an indication that existing MPLS techniques form an appropriate basis for the design of a fully- featured packet transport solution addressing all of the requirements of MPLS-TP. This document is not an Internet Standards Track specification; it is published for informational purposes.

RFC6658 - Packet Pseudowire Encapsulation over an MPLS PSN

This document describes a pseudowire mechanism that is used to transport a packet service over an MPLS PSN in the case where the client Label Switching Router (LSR) and the server Provider Edge equipments are co-resident in the same equipment. This pseudowire mechanism may be used to carry all of the required layer 2 and layer 3 protocols between the pair of client LSRs. [STANDARDS-TRACK]
