I was not able to be at the CCAMP meeting today but do have some comments on draft-shiomoto-ccamp-gmpls-mrn-reqs-00.txt    

 

It seems that the goals of the draft could be accomplished more simply by adopting the layer architecture as defined in ITU-T Recommendations G.805 and G.809.  By doing this, the specific boundaries between TDM, LSC, etc. don't have to be articulated as they are just layer networks.  Also, the designation of TDM does not include the notions of the layers within that (e.g., DS3, STS-1, VC4, etc.) which are important to transport equipment.  Adopting the layer architecture also enables a client layer to be supported by an inverse multipling layer such as provided by Virtual Concatenation.  Here a layer of finer granularity is use to support a layer of coarser granularity.
