Hi, Dear CCAMPers,

    We have posted a updated version of OTN LMP extension draft (with URL provided as follows). The changes are minor, mainly removing the part overlapping with OTN GMPLS control framework draft and minor grammatical tidy-ups. 

    We would like to request a review of this draft and comments/suggestions are more than welcome. 

Best Regards,

Xian ZHANG

Abstract:
   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.
