CURRENT_MEETING_REPORT_ Reported by Steve DeJarnett/IBM Minutes of the Internet Stream Protocol V2 BOF (ST2) The ST2 BOF met during the 1930-2200 session, opposite the Networking Multimedia Applications BOF (MULTIAPP) and the Open IAB Meeting (among others). The overlap with MULTIAPP in particular, and the multiple reschedulings of the BOF, may have limited the attendance, but in spite of those problems there were still 27 attendees. Presentations and Discussion The BOF started with presentations on existing ST-II implementations. Frank Hoffmann presented a description of the IBM ST-II implementation in the Heidelberg Transport System (HeiTS). Lou Berger presented information on BBN's work with ST-II in their T/20 router which is used in the backbone of the ARPA Defense Simulation Internet (DSI). Lou also spoke briefly about other work BBN was doing with ST-II. Luca Delgrossi discussed work going on in the BERKOM project in Germany, which has chosen ST-II as their network layer protocol for use in a multimedia teleservices pilot. After the presentations, discussion about interest in a working group to revise and clarify the ST specification was started. There was a great deal of discussion during the BOF about the problems that are known with ST-II as currently specified, including, but not limited to, the lack of a formal definition of ST-II states and the problems associated with efficiently supporting very large numbers of destinations in a single connection. Additional discussion focused around whether standardization of ST was warranted at this time. No clear consensus was reached on this issue. The discussion centered on whether now was an appropriate time to standardize given work in other areas and the possible emergence of other protocols which will deal with resource reservation. During the presentations on the various implementations, questions were raised which mostly dealt with implementation details. Those details have been left out of this summary except as they relate to the proposed mission of the working group. Results In the end, consensus was achieved on having a working group whose purpose was to clarify the current ST protocol in order to correct errors in the specification, and to make it easier to implement ST-II in a manner which is likely to be interoperable with other ST-II 1 implementations. The future of that protocol, whether continuing as an Experimental Protocol or moving forward as a Proposed Standard is still open for discussion. That discussion should be held at a later date when the results of the working group are demonstrable.
