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 MPLS-TP - 79th IETF
1st Last Call • -02 version last called • Received comments from WG and ITU-T (liaison) • A few themes in the comments • Missing references to / updates based on recent documents • General editorial comments • Nits and inconsistencies (thank you!) • Needed clarifications • Control of OAM vs Control Plane based OAM • PWs and ASON (ITU-T) MPLS-TP - 79th IETF
Draft -03 • -03 Version issued • Addressed all LC comments • Updated OAM Requirements section (2.3) to match current versions of [RFC5860] and [TP-OAM], and updated LSP/PW tables to match • Added Section 2.5, Identifier Requirement based on [TP-IDENTIFIERS], and updated LSP/PW tables to match • Addressed minor and editorial feedback • Revised editors list • Addressed Liaison comments • As described in mail to lists and in Liaison, see http://www.ietf.org/mail-archive/web/ccamp/current/msg11587.html • Note that only comments were responded to, other text changes were viewed as editorial suggestions/comments MPLS-TP - 79th IETF
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 clarifications • Some 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 MPLS-TP - 79th IETF
Next Steps • Address LC comments • Follow normal IETF process MPLS-TP - 79th IETF
