  1. LMP extensions for G.709 Optical Transport Networks CCAMP WG, IETF 85th, Atlanta, GA, USA draft-cecczhang-ccamp-gmpls-g709v3-lmp-00 Fatai Zhang, Xian Zhang, Dan Li (Huawei) D. Ceccarelli, D. Caviglia, Francesco Fondelli( Ericsson) Guoying Zhang ( CATR ) D. Beller, S.Belotti, PietroGrandi(Alcatel-Lucent )

  2. Overview of the Draft This. draft (LMP extension for OTN) Merged (Suggested in last IETF meeting) draft-zhang-ccamp-gmpls-g709-lmp-discovery draft-ceccarelli-ccamp-gmpls-g709-lmp-test Link Property Correlation: Discovering the capabilities of an ODU link Link Connectivity Verification: Verifying the connectivity of an ODU link

  3. Main Content of the Draft Link Property Correlation Link Connectivity Verification TEST behavior extension ODU link capability discovery Specify the Verify Transport Mechanism B A B A TEST TRACE monitoring extension • LMP discovery: • Supported TSG type (2.5G or 1.25G or both) • Supported signal types (LO ODUj) Specify the Trace Type & Trace Massages B A TRACE LMP behavior updates Indicate whether support of OTN-specific behavior +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |S|D|C|O| Must Be Zero (MBZ) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

  4. Next Steps • Since routing and signaling drafts become stable, We need to continue the work on LMP extension for OTN • Ready for WG adoption? We believe the extensions to LMP are necessary • Comments are always appreciated
