Internet Engineering Task Force Distributed File Systems Working Group DFS-WG dfs-wg@citi.umich.edu is a mailing list for ongoing discussions of the WG; administrative matters, such as requests to be added or dropped from the list, should be addressed to dfs-wg-request@citi.umich.edu. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= MEETING NOTES The DFS-WG met on 3 December 1990 at the Boulder IETF. The meeting was attended by Gregory Bruell gob@shiva.com Lida Carrier lida@apple.com Karen Frisa karen.frisa@andrew.cmu.edu Ken Hibbard hibbard@xylogics.com Russell Hobby rdhobby@ucdavis.edu Peter Honeyman honey@citi.umich.edu Ole Jacobsen ole@csli.stanford.edu Stev Knowles stev@ftp.com Carl Malamud carl@malamud.com Tony Mason mason+@transarc.com Matt Mathis mathis@pele.psc.edu Donald Morris morris@ucar.edu Chris Myers chris@wugate.wustl.edu Andy Nicholson droid@cray.com David O'Leary oleary@noc.sura.net Mark Stein marks@eng.sun.com John Veizades veizades@apple.com David Waitzman djw@bbn.com Carol Ward cward@spot.colorado.edu Attendees were added to the working group mailing list. The focal point of the WG continues to be wide-area NFS, i.e., NFS-across-the-Internet. Particular concerns fall into two areas: congestion control and authentication/authorization. Regarding the former, the consensus is that real progress on congestion control for NFS lies in the hands of vendors, not in those of Internet researchers and engineers. Furthermore, many attendees doubt whether the WG can do much to influence vendors to address problems that are long-standing and well-known. Along these lines, the following questions were raised: Can NFS' congestion handling be fixed? Could Sun fix it? Could the IETF fix it without Sun's cooperation? Is it legitimate to focus solely on Sun/RPC? Would Sun work with the IETF? Should we care? What role does AFS play? Or the Guelph NFS on TCP? The answers to these questions are not entirely obvious. Nevertheless, the WG is proceeding to document the shortcomings in NFS/RPC/UDP as they affect good Internet-citizenship. The WG urges backbone and regional network administrators to monitor the ports used by NFS (principally UDP/2049) when gathering network usage statistics; in this way, the IETF can gauge the severity of the wide-area NFS problem. Regarding authentication and authorization, the DFS-WG deems it appropriate to delegate such issues to the WGs dedicated to these areas. The DFS-WG will enumerate its special concerns and bring them to the attention of the appropriate security WGs at the next IETF meeting.
