54th IETF - Resource Allocation Protocol WG RAP Minutes Tuesday July 16th 2002 1pm Co-chairs: Scott Hahn, Mark Stevens (absent) Notes submitted by Diana Rawlins and Ravi Sahita Agenda (Agenda was posted on mailing list) ------ 1) Agenda bashing. 2) Chair reviewed current drafts- 3) Diana Rawlins - RSVP PCC PIB, acct feedback drafts 4) Kwok Chan - cops framework 5) Yacine El Mghazli - COPS usage for SLS- complements RSVP auth session that has passed last call 6) Christian Jacquenet - Enforcing an IP TE policy: early implementation results Current Status -Framework PIB - RFC editor queue RFC 3318 v09 -IESG discussion since first PIBs coming out - hence made informational -mgmt proposals are being reviewed, IAB meeting was held same time DiffServ PIB has gone thru the IESG, is in editors queue with RFC # 3317 - also informational. -framework for session setup has gone thru the IESG - Louis Hamer has made changes and the draft is back with the IESG and will through pretty shortly -Diana will talk about two drafts that are in the closing end the acct feedback framework and the associated PIB. -COPS TLS asked for a particular port - IESG doesn't want to give out specific ports for TLS - new draft uses the redirect command to transfer a clear connection to a secure connection. Bert to get some feedback from security experts. -Access Bind PIB is work in progress. COPS Framework - Kwok will talk about that shortly. Diana Rawlins presented the update on the Feedback Framework and Feedback PIB. There were no changes since IETF 53 on the framework and she briefly went over the editorial and table changes in the revised Feedback PIB draft. She recommended, on behalf of the other co-authors, that the Feedback Framework and Feedback PIB be submitted for working group last call. Kwok Ho Chan came to microphone to clarify that the DPE policies that were removed from the Feedback PIB were not needed because of later revisions to the Policy Framework PIB. Diana Rawlins presented the update on the RSVP Policy Control Criteria PIB. No changes were made since IETF 53. The draft is ready for working group last call. But the draft includes feedback usage tables and is dependent on Feedback Framework and Feedback PIB. The RSVP Policy Control Criteria PIB draft is waiting on the feedback framework drafts go through working group last call before being submitted for working group last call. Kwok Ho Chan gave an update on the working group item Architecture for COPS Based Policy Control Management Framework He went over the common COPS models, COPS-PR usage, inter-working RSVP outsourcing with provisioning and next steps. Bert Wijnen questioned that the Management Framework appeared to be introducing new COPS models and non-chartered work. Kwok Chan and Scott Hahn clarified that the scope of the Management Framework is to describe existing COPS mechanisms only. It does not contain any new COPS functionality. Bert raised a question that the Management Framework was not addressing the fundamental usage of COPS-PR and PIB definitions that were needed in an architecture management framework document. David Durham pointed out the while the COPS Management Framework was bounded to describing existing mechanisms such as inter-working between RSVP outsourcing and provisioning, it may stimulate examination of the RSVP Policy Control Criteria PIB and propose changes it. Yacine El Mghazli presented a non-working group item titled " COPS-PR Usage for SLS" This provides Service Level Specification policies using a combination of the outsourcing and provisioning policy model. Scott Hahn asked about the SLSTable being defined with a pib-access of INSTALL/ NOTIFY. The NOTIFY access mechanism in the SLSTable was to provide PDP with IP flow information from the PEP. Bert Wijnen also questioned the using the pib-access NOTIFY to gain flow information. Thi Mai Trang Nguyen, a co-author of the draft, explained that SLS needed to obtain IP flow information from the device. Diana Rawlins suggested that the authors consider using the feedback mechanism to obtain flow information rather than using the pib-access NOTIFY mechanism. Christian Jacquenet presented performance test results of an implementation of an IP Traffic Engineering Policy Information Base. A base measurement of the time required to use command language interface to configure 12 Linux routers platforms was compared to the provisioning time required when using the IP Traffic Engineering Policy Base. The cli mechanism took approximately 1 hour and the TE PIB approach required approximately 5 minutes. This test did not have a full PEP implementation of the COPS-PR protocol and TE PIB. David Durham offered the opinion that it would have very likely taken less time if a full COPS PR implementation in the PEP had been tested. David Perkins asked if another protocol such as SNMP had been used to benchmark against the COPS. Glen Waters also asked this. Christian responded that he had not included SNMP in his testing since he didn't think SNMP would provide the configuration solution that he desired.
