"ATM Signalling UNI 4.0 Support for IP over ATM" draft

Folks,

A new version of "ATM Signalling UNI 4.0 Support for IP over ATM"
has been submitted (see draft-ietf-ion-sig-uni4.0-00.txt). This 
draft applies to support of best effort IP service over ATM. The
main points emphasized in this memo are:

  - the default signalling message format SHOULD follow the "allowable
    combinations of ATM traffic related parameters" for the UBR service 
    category (detailed in UNI 4.0 and this memo)

  - PCR = link rate SHOULD be negotiated (down to minimum of PCR = 0)

  - frame discard capability MUST be supported

  - no recommendations are made about the use of the ABR service category
  
As an aside, you may have noticed that the draft, 
draft-borden-intserv-atm-mapping-00.txt, also touches upon ATM signalling
for best effort IP service for completeness. We are currently discussing how 
to aling/merge the two memos.

see you,

Maryann Maher
