RE: Doubt in draft ccamp-gmpls-sonet-sdh-00.txt

Hello Manoj,

The virtual concatenation is indicated in a separate field (NVC). The reason
is to allow to code the virtual concatenation of contiguously concatenated
signals (like the virtual concatenation of several STS-3c's.

Kind regards,

Eric

Hi,

     I have a doubt in draft ietf-ccamp-gmpls-sonet-sdh-00.txt :

  The CCT field can have values no concatenation, standard
concatenation, arbitrary, vendor specific.
But why can't virtual concatenation ? It was there in original draft.
But in the exmaples section for SDH/SONET signals, it is shown that a
virtually concatenated signal can be built using NVC field with CCT
value as 0. Please clarify the reason in doing so.

Regards,
manoj.
