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

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,
