RFC 6718 PW Redundancy August 2012

چکیده
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 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) mes...
متن کاملRedundancy Mechanism for Inter-domain VPLS Service
In many existing Virtual Private LAN Service (VPLS) inter-domain deployments (based on RFC 4762), pseudowire (PW) connectivity offers no Provider Edge (PE) node redundancy, or offers PE node redundancy with only a single domain. This deployment approach incurs a high risk of service interruption, since at least one domain will not offer PE node redundancy. This document describes an inter-domai...
متن کاملRFC 6870 PW 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 t...
متن کاملVirtual 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 accommoda...

The MPLS Transport Profile (MPLS-TP) is based on a profile of the MPLS and Pseudowire (PW) procedures as specified in the MPLS Traffic Engineering (MPLS-TE), PW, and Multi-Segment Pseudowire (MS-PW) architectures developed by the Internet Engineering Task Force (IETF). The International Telecommunication Union Telecommunication Standardization Sector (ITU-T) has specified a Transport Network ar...
