- Hello,
-
- I read with great interest your posting, "Hop-by-hop flow control
- (was: Re:clarifying the role of SSCOP?)" to the comp.dcom.cell-relay
- mailing list on Nov. 12, 1992.
-
- The hop-by-hop alternative to credit systems that you proposed
- (traffic class distinctions, separate buffers for traffic classes, "reverse
- bursty congestion experienced" backward indication) is remarkably
- similar to the ATS concept and its ramifications that has been propounded
- by Prof. Aurel A. Lazar and his group at the Center for Telecommunications
- Research (CTR) at Columbia University in New York City.
-
- ATS stands for Asychronous Time Sharing and is a variant of ATM.
- The aspects of ATS dealing with joint scheduling and admission control have
- been published recently by J. Hyman and A.A. Lazar in the 1992 Proceedings
- of the ACM SIGCOMM Conference. Other work has been done in the areas
- of integrated reference model, knowledge-based monitoring, single
- node/switch scheduling and distributed scheduling. For example, beyond
- using overload watermarks to initiate backward congestion indication,
- one could take advantage of the highly correlated nature of broadband
- traffic to do traffic prediction and send congestion indications well in
- advance of the actual congestion conditions. (See, for example,
- J.T. Amenyo, A.A. Lazar and G. Pacifici's paper in the Proceedings of the
- IEEE INFOCOM 1992 Conference.)
-
- If you are interested in learning more about results in the above areas, I
- suggest you contact Prof. A.A. Lazar or Dr. Giovanni Pacifici at CTR.
- I believe several of the documents are still online for you to access by
- anon. ftp.
-
- Cheers.
