Summary:
|
Recommendation ITU-T G.8131/Y.1382 provides architecture and mechanisms for subnetwork connection (SNC) protection switching for MPLS transport profile (MPLS-TP) networks. It describes the SNC protection architectures type, the uni- and bidirectional switching types and the revertive/non-revertive operation types. It defines an automatic protection coordination protocol used to coordinate both ends of the protected domain.
Amendment 1 provided the format of APC specific information, and descriptions about management (MI) signals and trail protection architecture.
Amendment 2 to Recommendation ITU-T G.8131/Y.1382 (2014) provided:
- Support for pseudowire (PW) protection.
- Modifications to the references of terms related to new Recommendation ITU-T G.808
Amendment 3 provides updates on the following:
- Initialization behaviour,
- State transition modification, and
- Operation related to state transition table lookup.
