Context & Problem Statement
Multiple switching capabilities exist in server LayerSwitching Cap, Adaptation & Switching Granularity Above info is required for E2E
TE path computationsSignaling also needs to carry server layer infoExisting RFCs do not cover all aspects of multi-layer . For e.g. OTN mux layer identificationSlide3
