Abstract

The MPLS Generic Associated Channel (G-ACh) is defined and described in [RFC5586]. It provides an auxiliary logical data channel over which a variety of protocols may flow. Each such data channel is associated with an MPLS Label Switched Path (LSP), a pseudowire, or a section (link). An important use of the G-ACh and the protocols it supports is to provide Operations, Administration, and Maintenance (OAM) [RFC6291] capabilities for the associated LSP, pseudowire, or section. Examples of such capabilities include Pseudowire Virtual Circuit Connectivity Verification (VCCV) [RFC5085]; Bidirectional Forwarding Detection (BFD) for MPLS [RFC5884]; and MPLS packet loss, delay, and throughput measurement [RFC6374]; as well as OAM functions developed for the MPLS Transport Profile (MPLS-TP) [RFC5921].

Abstract

   The MPLS Generic Associated Channel (G-ACh) provides an auxiliary    logical data channel associated with a Label Switched Path (LSP), a    pseudowire, or a section (link) over which a variety of protocols may    flow.  These protocols are commonly used to provide Operations,    Administration, and Maintenance (OAM) mechanisms associated with the    primary data channel.  This document specifies simple procedures by    which an endpoint of an LSP, pseudowire, or section may inform the    other endpoints of its capabilities and configuration parameters, or    other application-specific information.  This information may then be    used by the receiver to validate or adjust its local configuration,    and by the network operator for diagnostic purposes.
