The case of most immediate interest to me is TCP/IP over DDN Standard X.25 connections. As far as I know, there is no standard or published guideline which would stop me from multiplexing everything (to the same Network-level destination, of course) on a single X.25 connection; at the other extreme, I might open a new X.25 connection for each datagram. The same issue arises with ISO TP over X.25. Does it follow that the same algorithm is "best" for both cases? The case of ISO CLNP over X.25 seems to combine the two cases above. This is what I understand GOSIP to specify for the future, so this case is also interesting. I've heard that some problems in the ARPANET transition to PSN 7.0 had to do with this topic. So I imagine there are some interesting issues somewhere underlying the decisions an implementor might make, and perhaps some interoperation problems with some choices. I'd like to get a handle on this whole area. You're all invited to describe the behavior of existing implementations or your conception of the Right Thing To Do. Thanks in advance for all info, insights, comments, and suggestions... Bill Barns / MITRE-Washington / barns@gateway.mitre.org
