RE: [BULK] VCAT/LCAS draft update...

[<julien.meuric@orange-ftgroup.com>]

Hi all.

I would even add that the diversely routing scenario is not different in GMPLS from configuration-based provisioning: from the data plane point of view, nothing is new.

Regards,

Julien

Hi Deborah,

You replied:

Minimum delay in G.707 is 125 usec (micro-seconds)...

Maximum differential delay depends on implementation.
Differential is the difference between the largest
propagation delay of one of the members and the
smallest propagation delay of one of the members.
The sink VCAT/LCAS function is capable of detecting
and reporting whether one or more members does not fit
the differential delay capability.

Cheers, Huub.
