2. 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

3. 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

4. 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

5. 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.
