RFC6073 - Segmented Pseudowire
This document describes how to connect pseudowires (PWs) between different Packet Switched Network (PSN) domains or between two or more distinct PW control plane domains, where a control plane domain uses a common control plane protocol or instance of that protocol for a given PW. The different PW control plane domains may belong to independent autonomous systems, or the PSN technology is heterogeneous, or a PW might need to be aggregated at a specific PSN point. The PW packet data units are simply switched from one PW to another without changing the PW payload. [STANDARDS-TRACK]
RFC6240 - Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Circuit Emulation over Packet (CEP) MIB Using SMIv2
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) circuits over a Packet Switch Network (PSN). [STANDARDS-TRACK]
RFC6307 - Encapsulation Methods for Transport of Fibre Channel Traffic over MPLS Networks
A Fibre Channel pseudowire (PW) is used to carry Fibre Channel traffic over an MPLS network. This enables service providers to take advantage of MPLS to offer "emulated" Fibre Channel services. This document specifies the encapsulation of Fibre Channel traffic within a pseudowire. It also specifies the common procedures for using a PW to provide a Fibre Channel service. [STANDARDS-TRACK]
RFC6310 - Pseudowire (PW) Operations, Administration, and Maintenance (OAM) Message Mapping
This document specifies the mapping and notification of defect states between a pseudowire (PW) and the Attachment Circuits (ACs) of the end-to-end emulated service. It standardizes the behavior of Provider Edges (PEs) with respect to PW and AC defects. It addresses ATM, Frame Relay, Time Division Multiplexing (TDM), and Synchronous Optical Network / Synchronous Digital Hierarchy (SONET/SDH) PW services, carried over MPLS, MPLS/IP, and Layer 2 Tunneling Protocol version 3/IP (L2TPv3/IP) Packet Switched Networks (PSNs). [STANDARDS-TRACK]
RFC6391 - Flow-Aware Transport of Pseudowires over an MPLS Packet Switched Network
Where the payload of a pseudowire comprises a number of distinct flows, it can be desirable to carry those flows over the Equal Cost Multiple Paths (ECMPs) that exist in the packet switched network. Most forwarding engines are able to generate a hash of the MPLS label stack and use this mechanism to balance MPLS flows over ECMPs.
This document describes a method of identifying the flows, or flow groups, within pseudowires such that Label Switching Routers can balance flows at a finer granularity than individual pseudowires. The mechanism uses an additional label in the MPLS label stack. [STANDARDS-TRACK]
RFC6423 - Using the Generic Associated Channel Label for Pseudowire in the MPLS Transport Profile (MPLS-TP)
This document describes the requirements for using the Generic Associated Channel Label (GAL) in pseudowires (PWs) in MPLS Transport Profile (MPLS-TP) networks, and provides an update to the description of GAL usage in RFC 5586 by removing the restriction that is imposed on using GAL for PWs, especially in MPLS-TP environments. [STANDARDS-TRACK]
RFC6478 - Pseudowire Status for Static Pseudowires
This document specifies a mechanism to signal Pseudowire (PW) status messages using a PW associated channel (ACh). Such a mechanism is suitable for use where no PW dynamic control plane exits, known as static PWs, or where a Terminating Provider Edge (T-PE) needs to send a PW status message directly to a far-end T-PE. The mechanism allows PW Operations, Administration, and Maintenance (OAM) message mapping and PW redundancy to operate on static PWs. This document also updates RFC 5885 in the case when Bi-directional Forwarding Detection (BFD) is used to convey PW status-signaling information. [STANDARDS-TRACK]
RFC6667 - LDP 'Typed Wildcard' Forwarding Equivalence Class (FEC) for PWid and Generalized PWid FEC Elements
The "Typed Wildcard Forwarding Equivalence Class (FEC) Element" defines an extension to the Label Distribution Protocol (LDP) that can be used when requesting, withdrawing, or releasing all label bindings for a given FEC Element type is desired. However, a Typed Wildcard FEC Element must be individually defined for each FEC Element type. This specification defines the Typed Wildcard FEC Elements for the Pseudowire Identifier (PWid) (0x80) and Generalized PWid (0x81) FEC Element types. [STANDARDS-TRACK]
RFC6718 - Pseudowire Redundancy
This document describes a framework comprised of a number of scenarios and associated requirements for pseudowire (PW) redundancy. A set of redundant PWs is configured between provider edge (PE) nodes in single-segment PW applications or between terminating PE (T-PE) nodes in multi-segment PW applications. In order for the PE/T-PE nodes to indicate the preferred PW to use for forwarding PW packets to one another, a new PW status is required to indicate the preferential forwarding status of active or standby for each PW in the redundant set. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6723 - Update of the Pseudowire Control-Word Negotiation Mechanism
The control-word negotiation mechanism specified in RFC 4447 has a problem when a PE (Provider Edge) changes the preference for the use of the control word from NOT PREFERRED to PREFERRED. This document updates RFC 4447 and RFC 6073 by adding the Label Request message to resolve this control-word negotiation issue for single-segment and multi-segment pseudowires. [STANDARDS-TRACK]
RFC6870 - Pseudowire Preferential Forwarding Status Bit
This document describes a mechanism for signaling the active and standby status of redundant Pseudowires (PWs) between their termination points. A set of Redundant PWs is configured between Provider Edge (PE) nodes in single-segment pseudowire (SS-PW) applications or between Terminating Provider Edge (T-PE) nodes in Multi-Segment Pseudowire (MS-PW) applications.
In order for the PE/T-PE nodes to indicate the preferred PW to use for forwarding PW packets to one another, a new status bit is defined. This bit indicates a Preferential Forwarding status with a value of active or standby for each PW in a redundant set.
In addition, a second status bit is defined to allow peer PE nodes to coordinate a switchover operation of the PW.
Finally, this document updates RFC 4447 by adding details to the handling of the PW status code bits in the PW Status TLV.
RFC7023 - MPLS and Ethernet Operations, Administration, and Maintenance (OAM) Interworking
This document specifies the mapping of defect states between Ethernet Attachment Circuits (ACs) and associated Ethernet pseudowires (PWs) connected in accordance with the Pseudowire Emulation Edge-to-Edge (PWE3) architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects.
RFC7079 - The Pseudowire (PW) and Virtual Circuit Connectivity Verification (VCCV) Implementation Survey Results
The IETF Pseudowire Emulation Edge-to-Edge (PWE3) working group has defined many encapsulations of various layer 1 and layer 2 service- specific PDUs and circuit data. In most of these encapsulations, use of the Pseudowire (PW) Control Word is required. However, there are several encapsulations for which the Control Word is optional, and this optionality has been seen in practice to possibly introduce interoperability concerns between multiple implementations of those encapsulations. This survey of the Pseudowire / Virtual Circuit Connectivity Verification (VCCV) user community was conducted to determine implementation trends and the possibility of always mandating the Control Word.
RFC7189 - Virtual Circuit Connectivity Verification (VCCV) Capability Advertisement for MPLS Transport Profile (MPLS-TP)
This document specifies how signaling and selection processes for Pseudowire (PW) Virtual Circuit Connectivity Verification (VCCV) are modified to ensure backward compatibility and allow use of proactive Connectivity Verification (CV), Continuity Check (CC), and Remote Defect Indication (RDI) over MPLS Transport Profile (MPLS-TP) PWs. This document introduces four new CV types and, to accommodate them, a new VCCV Extended CV parameter for PW Interface Parameters Sub-TLV is defined.
RFC7267 - Dynamic Placement of Multi-Segment Pseudowires
RFC 5254 describes the service provider requirements for extending the reach of pseudowires (PWs) across multiple Packet Switched Network domains. A multi-segment PW is defined as a set of two or more contiguous PW segments that behave and function as a single point-to-point PW. This document describes extensions to the PW control protocol to dynamically place the segments of the multi-segment pseudowire among a set of Provider Edge (PE) routers. This document also updates RFC 6073 by updating the value of the Length field of the PW Switching Point PE Sub-TLV Type 0x06 to 14.
RFC7275 - Inter-Chassis Communication Protocol for Layer 2 Virtual Private Network (L2VPN) Provider Edge (PE) Redundancy
This document specifies an Inter-Chassis Communication Protocol (ICCP) that enables Provider Edge (PE) device redundancy for Virtual Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS) applications. The protocol runs within a set of two or more PEs, forming a Redundancy Group, for the purpose of synchronizing data among the systems. It accommodates multi-chassis attachment circuit redundancy mechanisms as well as pseudowire redundancy mechanisms.
RFC7338 - Requirements and Framework for Point-to-Multipoint Pseudowires over MPLS Packet Switched Networks
This document presents a set of requirements and a framework for providing a point-to-multipoint pseudowire (PW) over MPLS Packet Switched Networks. The requirements identified in this document are related to architecture, signaling, and maintenance aspects of point-to-multipoint PW operation. They are proposed as guidelines for the standardization of such mechanisms. Among other potential applications, point-to-multipoint PWs can be used to optimize the support of multicast Layer 2 services (Virtual Private LAN Service and Virtual Private Multicast Service).
RFC7392 - Explicit Path Routing for Dynamic Multi-Segment Pseudowires
When set up through an explicit path, dynamic Multi-Segment Pseudowires (MS-PWs) may be required to provide a simple solution for 1:1 protection with diverse primary and backup MS-PWs for a service, or to enable controlled signaling (strict or loose) for special MS-PWs. This document specifies the extensions and procedures required to enable dynamic MS-PWs to be established along explicit paths.
