  2. Requirements NNI • Policy in server network may require information in RRO be edited, summarized or removed. E.g., GMPLS UNI, inter-domain, etc. • Client nodes need to know how RRO contents has been manipulated. • RRO reduction to avoid packet fragmentation. UNI-C UNI-N NNI UNI-N UNI-C

  3. Requirements – Cont. • The requirement was identified in the following WG drafts: • SRLG Recording - draft-ietf-ccamp-rsvp-te-srlg-collect. • TE Metric Recording - draft-ietf-ccamp-te-metric-recording. • Working group feedback was to define a generic RRO-edit mechanism, which is extendable to all RRO sub-objects.

  4. RRO-edit RRO sub-object • Insert a new RRO-edit sub-object for each subobjectbeen edited. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | Edited type |E|P|S|R|reserve| +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • Edited type: The type of the sub-object being manipulated. • E : Edited bit – subobject(s) of edited typehas been edited in some way. • P : Partial bit – subobject(s) of edited type is known to have incomplete info. • S: Summary bit – subobject(s) of edited type has been summarized. • R: Removed bit – subobject(s) of edited typehas been removed.

  6. Next Steps • Work on a couple of working group documents depends on this draft. • Authors would like to request a quick call for WG adoption.
