Hi,
The draft "draft-ietf-ccamp-gmpls-sonet-sdh-04.txt"
specifies as follows for the traffic parameters -
"Each transform is optional and must be ignored if
zero, except MT that cannot be zero and is ignored if equal to
one"
Is'nt it that the transform should be "mandatory" applied
and not optionally as mentioned above. Consider for example, a request is
received from an upstream peer with Signal Type as 6 indicating STS-3c SPE and
NVC as 4 indicating a final signal which comprises of 4 virtually concatenated
STS-3c SPEs. This would mean a bandwidth of (155.5*4)Mbps requested by the
upstream. Now if the LSR decides not to apply virtual concatenation,
as inferred from the draft and gives back a mapping corresponding to STS-3c
SPE, it would result in net bandwidth allocation of 155.5 Mbps only. Instead the
LSR should reject the LSP request.
The same argument holds good for other traffic parameters
also.
Kindly reqly back if I am missing something....
Thanks in advance.
Regards
Vinay
