A Framing Strategy for Congestion Management

S.J. Golestani, Bellcore

One-line summary: Admission based congestion control on multiple streams with varying real-time constraints. Group packets with similar delay requirements into "time frames", multiplex the frames onto each link, and at each switch/router, minimize the "phase difference" (delay between extracting packet from arriving frame and placing it in next departing frame of the same class).

Overview/Main Points


Nice statistical multiplexing argument with some mathematically developed bounds on queueing delay and buffering---provided you can do strict admission control and that your traffic fits well into these constant-frame-size, constant-bit-rate classes. (Seems like you could dynamically change the class of a connection if needed, but this is a whole new layer of scheduling and is not even mentioned in the paper.)
