Frame Relay Service Type for L2TP
draft-vasavada-l2tpext-fr-svctype-00.txt
10 minutes
Presentation
Questions/Comments:
Mark - less overloading AVPs. Sub address types are used with ISDN so maybe we should use another AVP.
Nishit - agreed.
Mark - no way to insure data integrity - why it isn't turning on the UDP checksum. You can say MUST. Discusses PPP, UDP with L2TP and use of checksums. L2TP specific checksum mentioned may be a requirement of the PWOT.
Andrew Malis - MUST UDP checksum - issues with the header MTU issues?
Fragmentation and reassembly - go to the FRF.5 with regards functionality (for ATM but still applicable). T1.618 should be changed ITU Q.922 Q.923.
Kevin - CIR mentioned? Nishit - next version. With MPLS why? Mark - something for PWOT.

Danny
Presentation
Mentioned that Wei Luo did the update
Questions/Comments:
Q: PPP - multiple flows within a PPP session?
Danny: out of scope
David: problem with L2TP, sequence numbers, and flow based diffserv - be careful
Mark: do not turn on sequence numbers in this case
Mark: classification of flows and mapping - one method is pure mapping and doesn't use this. Text to talk about that case, another case, is this common knowledge?
Danny: welcome to the proposal
Mark: do you reflect?
Thomas: Possible to modify the existing PHBID? Is there a message to use?
Mark: SLI or create a new message type.
Mark: Why?
Thomas: Won't know until after authentication
Mark: should consider it.
None
