MPLS-TP - 79th IETF2 Draft Objectives Provide a context for the MPLS-TP control plane Based on MPLS-TP RFCs and drafts Notably requirements, framework and survivability Based on existing IETF control plane – LSPs and PWs Apply GMPLS/MPLS, PW control planes wherever possible Reviews control plane requirements Derived from other requirements, but stated in the context of control plane All requirements must be satisfied By the LSP control plane alone for Network Layer Adaptation (FW Section 3.4.3) By the combination of PW and LSP control planes for Pseudowire Adaptation (FW Section 3.4.2) Provides a mapping of requirements to existing IETF mechanisms Identifies gaps Does define any protocol extensions Extensions to be covered in other drafts as needed Reminder: TP does not require a control plane Drives which functions are in OAM and which are in Control Plane
