Summary:
|
Amendment 1 to Recommendation ITU-T G.8032/Y.1344 adds two informative appendices. Appendix X (Minimizing segmentation in interconnected rings) addresses a possible case of multiple faults that could cause segmentation in a network of interconnected rings. This appendix suggests an optimization that uses additional management information and configuration of MEPs in order to minimize the effects of similar multiple fault conditions. Appendix XI (End-to-end service resilience) addresses the situation where an Ethernet service that traverses a protected ring may start and end outside the ring. In order to provide full service protection, there is a need for the ring protection to interact with the full service protection that may be supplied by the mechanism described in Recommendation ITU-T G.8031/Y.1342.
