MPLS-TP - 79th IETF 2
Draft ObjectivesProvide 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 requirementsDerived from other requirements, but stated in the context of control planeAll 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 mechanismsIdentifies gaps
Does define any protocol extensionsExtensions to be covered in other drafts as needed
Reminder: TP does not require a control planeDrives which functions are in OAM and which are in Control Plane

MPLS-TP - 79th IETF 5
Current Status
Draft in joint CCAMP, PWE, MPLS last call
Completes November 9th
Document also sent to ITU-T via liaison• Response sent Nov. 5
Some comments already received Editorial and minor clarificationsSome relate to document scope• Requirements come from other documents,
those documents need to be changed to impact CP requirements
• Document scope is limited to CP considerations
– Non-CP considerations are out-of-scope
