Title : Link Management Protocol (LMP) extensions for G.709 Optical Transport Networks Author(s) : Fatai Zhang Dan Li Daniele Ceccarelli Diego Caviglia Guoying Zhang Pietro Grandi Sergio Belotti Filename : draft-zhang-ccamp-gmpls-g709-lmp-discovery-05.txt Pages : 16 Date : 2011-10-13 Recent progress of the Optical Transport Network (OTN) has introduced new signal types (i.e., ODU0, ODU4, ODU2e and ODUflex) and new Tributary Slot granularity (1.25Gbps). Since equipments deployed prior to recently defined ITU-T recommendations only support 2.5 Gbps Tributary Slot granularity and ODU1, ODU2 and ODU3 containers, the compatibility problem should be considered. In addition, a Higher Order ODU (HO ODU) link may not support all the types of Lower Order ODU (LO ODU) signals defined by the new OTN standard because of the limitation of the devices at the two ends of a link. In these cases, the control plane is required to run the capability discovering functions for the evolutive OTN. This document describes the extensions to the Link Management Protocol (LMP) needed to discover the capability of HO ODU link, including the granularity of Tributary Slot to be used and the LO ODU signal types that the link can support.
