Re: VCAT/LCAS

Hello Dan,

You wrote:


When we consider the requirements in section 3, do we also need to
consider the scenario which the Ethernet service is supported by Xc
or by the combination of Xc and Xv?


Contiguous concatenation Xc and virtual concatenation Xv
cannot be combined (there is only one exception: an STS-3c can
be virual concatenated)


Another scenario is if we have the optional Xc and Xv flexible
adapatations at both ends, does the signaling need to support the
selection?


A selection is certainly needed to match the transport capability
with the required bandwidth. A selection can be:
- a single VC-n
- a single VC-n-Xc
- a VC-n-Xv which provides additional flexibility if LCAS
   is supported.

Cheers, Huub.
