Re: MS-SPring [Was: Moving forward with the CCAMP charter]

Hi Diego, there is interest on my part on working with other protection schemes. In general I'm interested in the inter-operation and optimal selection of protection/restoration schemes at different layers. I'm busy this week but next week I expect to also get back to the VCAT draft and review the various notes and such from the other SDOs.

Subject:    MS-SPring [Was: Moving forward with the CCAMP charter]

Hi Diego,

I can well believe that this is something that should/could be of interest
to CCAMP.

It would be premature, however, to put explicit milestones on our charter
without first seeing some work on the subject and support from the
community.

At the very least we would need to scope the problem and understand
whether there is any work to be done. If anyone wants to write a draft on
this so that we can all understand the problem space, I am sure it would
be welcomed.

Cheers,
Adrian

Hi Adrian and all,
                 I've a question about GMPLS interworking with inherent
protection scheme.

With inherent protection scheme I mean e.g. MS-SPRing in transport


network.


MS-SPring is widely deployed and IMHO interworking between that


protection


scheme and GMPLS should be foreseen.
Unfortunately there are some constraints to be satisfied (timeslot
interchange and squelching table) when an LSP is created on a MS-SPRing.

And now the question is this kind of interworking something that should


be


covered in CCAMP (I know that there are some Study Point in ITU-T to


cover


this issues)?

IMHO I think the answer is yes but I like to know the feeling of the


other


guys here.

Regards

Diego
