LMP Behavior Negotiation CCAMP WG, IETF 76th, Hiroshima, Japan draft-li-ccamp-lmp-behavior-negotiation-00.txt Dan Li

Problem Statement New LMP behaviors and protocol extensions are being introduced –RFC 4204: Standard LMP Messages (Msg Type 1-20) –RFC 4207: TRACE behavior for SDH/SONET (Msg Type 21-31) –RFC 4209: DWDM behavior (C-type 2 in CONFIG Object) –DCSC draft (under IESG review): Data Channel Consistency Check behavior (Msg Type 32-34) Unfortunately, no procedure to discover the LMP capabilities of peer LSRs is defined so far

Enhanced Behavior Config Config Message (Msg Type = 1) ::= CONFIG Class = 6 o C-Type = 1, HelloConfig, defined in [RFC4204] o C-Type = 2, LMP_WDM_CONFIG, defined in [RFC4209] o C-Type = 3, ENHANCED_BEHAVIOR_CONFIG Newly defined!

New C-Type (3) for CONFIG Object |S|D| (Reserved) | S: 1 bit This bit indicates support for the SONET/SDH TRACE messages defined in [RFC4207]. D: 1 bit This bit indicates support for the Data Channel Status Confirmation messages defined in [DCSC]. Note: The Reserved field MUST be sent as zero and MUST NOT be ignored on receipt. This allows the detection of supported/unsupported LMP behaviors.

Next Steps Adopt as a WG document –Very simple draft Update with LMP extensions of G.709 (OTN) control –draft-ceccarelli-ccamp-gmpls-g709-lmp-test-01.txt Comments?
