Minutes of the Quality of Service Routing (QoSR) working group meeting at the 40th IETF in Washington, DC starting at 0900 on Thursday, December 11th, 1997. Minutes were recorded by Hal Sandick and Eric Crawley. Eric Crawley started the meeting off with a quick introduction and the the agenda. The slides are available in: ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/agenda.pdf ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/agenda.ps ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/agenda.ppt Hal Sandick gave a quick update on the QoSR framework document (draft-ietf-qosr-framework-02.txt). The slides are available in: ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/qosrfrwk.ps ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/qosrfrwk.pdf ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/qosrfrwk.ppt Hal went through the last round of changes to the document. They were minor and included additional background information and editorial changes. The Framework is being sent out for last call ending on 1/12/98. As part of the last call, changes to the framework document may include additional information on of Type of Service (TOS) routing which has been used in the past. Last, the authors feel that it is too early to focus on QoS routing to support the Differential Services work going on in the Integrated Services work group. The presentation went quickly and the comments that were made were requested to be replicated onto the mailing list. Mark Pullen next gave a update on the QoSIP models from George Mason University. The slides are available at: ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/pullenqosip.ps ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/pullenqosip.ppt ftp://ftp.networking.ibm.com/pub/standards/qosr/ietf1297/pullenqosip.pdf Several groups have already downloaded the models available at http://bacon.gmu.edu/qosip but there were some bugs in the initial version that made it difficult for others to run the models. A new version has been produced that should be much better. Mark's group plans to integrate a new OSPF model available from Optnet/Mil3 in January, 1998. They plan to update the documentation and resubmit the previous Internet Drafts they produced from the simulation data. They would like to expand the model using updated Internet Drafts and optimize the performance a bit. The current simulation takes about a week of computation time on a Sparc 20 for an 84 node network. Mark had a few graphs to show some results. One of the preliminary conclusions is that the demands placed on systems by additional Dijkstra calculations and LSA traffic are manageable. For more information, including Mark's graphs, see http://bacon.gmu.edu/qosip. The session ended with call for a discussion about the work group's future. There were no comments made. It seems that the work group will go dormant after the Framework document is completed. The meeting ended after 20 minutes. -------------------------------------------------------------------------------- Eric and Hal Hal Sandick IBM, NHD (919) 254-4614 sandickh@ibmusm20 (internal ibm) sandickh@us.ibm.com (external)
