RE: Working Group Last Call on draft-ietf-ccamp-gmpls-rsvp-te-call-00.txt



Hi,

 

I looked over this draft over the weekend and I have some comments and questions.

 

1)       It is hard to understand why a new feature (call control) is being designed as an extension to a notification message.  The resulting protocol design obscures the function of the protocol and creates special case processing that may lead to problems.  Is there a reason that new message types were not specified for call request and response?

2)       Given the stated intent of maintaining strict independence between call and connection control, were other (existing) call control protocols considered (rather than beginning a new call control protocol specification)?

3)       The network models being used in section 4.3 and section 7 are not clear.  In particular the relationships between the call controllers, network boundaries, ingress/egress nodes, and ingress/egress links are not clear.  Figures would be very helpful here.

4)       Simultaneous Call and connection establishment can be very handy in the common case of a call with a single connection.  This model should be supported (and in fact it is in the case of so called “connection setup without a call”).

5)       The call control mechanism defined appears to support only IPv4 or IPv6 addressed endpoints from a single address space.  Is this correct?

 

Regards,

Ben

Subject: Working Group Last Call on draft-ietf-ccamp-gmpls-rsvp-te-call-00.txt

 

All,

 

As discussed at the last CCAMP meeting, the authors of this draft would like the draft to be considered for WG Last Call. Although it appears to be a 00 draft, the material was previously in draft-ietf-ccamp-gmpls-te-ason-03.txt. At least one implementation exists.

 

This email begins a two week Working Group Last Call on the draft:

 

The last call will complete on June 19th at 9PM EST.

 

Comments should be addressed to the mailing list or, if anonymity is preferred, to me. On a point of procedure, as both Adrian and myself are co-authors, anyone who has an issue with this draft going to WG Last Call should contact one of our ADs, Ross (rcallon@juniper.net) or Bill (fenner@research.att.com).

 

Thanks,

Deborah
