MPLS-TP - 78th 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

Some comments already received Received comments via ITU-T Liaison• Actual comments missing from liaison (presumably
by mistake)
A few themes in the commentsMissing references to recent drafts• Notably identifiers and data-plane
General editorial comments• Nits and inconsistencies (thank you!)
Needed clarifications Control of OAM vs Control Plane based OAMPWs and ASON (ITU-T)
