Motivations of this draft Measuring LSP provisioning performance in the lab Requirements of dynamical provisioning capability in GMPLS Networks: interactive broadband multimedia services. Let the requirement of applications and the provisioning capability of the network be mapped to each other Measuring the provisioning performance in operational networks Monitor the control plane performance in real-time Helpful to the GMPLS network maintenance and optimization. Standardized metrics and the way to measure them precisely should be defined In scope of CCAMP charter: “Definition of MIB modules and other OAM techniques relevant to the protocols and extensions specified within the WG.” Maximize common understanding of LSP provisioning performance between the service providers and network users/applications

Changes with version 00 Explicit statements on applicability of including the defined metrics in GMPLS-TE-STD-MIB In abstract and introduction A couple of changes in the text Correct the errors in 7.6, 8.7 Revising 4.1, 4.7, 5.4, 6, 8.7, 9.1 Measurement time unit changed from ‘seconds’ to ‘milli-seconds’ In all effected sections

Topics discussed in the group Motivating the metrics The metrics themselves received no objections. They seem well motivated through the discussions in the group. Setup Ratio Will be added in the next update RSVP convergence and graceful restart Will be considered in the next update Including a set of metrics into GMPLS-TE-STD-MIB A reference to RFC 4802 will be added in the next update Discussions on harmonizing with Samir’s draft on RSVP-TE convergence (In BMWG) Rough consensus reached: retaining this draft in CCAMP Further work underway Rerouting performance It is still a pending problem, need more input from the group and WG

Next Steps Reach a consensus in CCAMP on the defined metrics Harmonization with RSVP-TE convergence draft More discussions on MIB inclusion of some of the metrics LSP rerouting performance P2MP performance metrics Authors need more feedback in the WG mailing list.
