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

Hi Deborah,

You replied:


Shouldn't be a problem if the data plane is based on ITU - so it would
need to support (at minimum) ITU's G.707 minimum differential delay
requirements for VCAT.


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.

Dear Greg,
One additional problem with VCAT/LCAS is the amount of differential
delay
supported at the destination node. Can it be mentioned as a note that
co-routing or diversely routing is also based on the availability of
enough
sufficient differential delay buffer size at the destination node? 
Regards,
Jishnu A

Hi folks, I edited the VCAT/LCAS draft to use the CALL_ATTRIBUTES object

from the MLN extensions draft.
We define a new VCAT TLV for use in the aforementioned object. All procedures and encodings otherwise are the same as the previous draft. Note that the draft will now be contingent on the MLN extensions draft moving forward.
