Scope and Objectives n Provide a framework for MPLS-TP-based survivability, introducing the functional architecture n The general description of the functional architecture is applicable for both LSPs and PWs. n Detailed consideration for the protection of PWs in MPLS-TP networks will be covered in a separate document. We expect that this draft will probably be worked on within the PWE 3 working group. n n Highlight areas where new work is required. Use the recovery terminology defined in RFC 4427 as normative. Note that RFC 4427 draws on G. 808. 1. n Refer to the requirements specified in RFC 5654. n Use similar principles of the recovery schemes as those defined analyzed in RFC 4427 and RFC 4428.

Status and Next Steps n Additional conference call was held to review the document. n The document is in a good shape and is progressing rapidly at the moment n Version 2 is currently with SG 15 for early review n Good reviews from a number of individuals.
