On adaptive bandwidth sharing with rate guarantees Conference Paper uri icon

abstract

  • This paper questions the notion that queueing systems should closely emulate a GPS system. Instead of emulating GPS, it proposes three modified scheduling schemes which preserve the rate guarantees of fair queueing (and hence preserve deterministic delay bounds) but adaptively redistribute the excess bandwidth such that either losses are reduced or delays equalized. It compares the performance of the proposed schemes to that of fair queueing using different traffic sources such as voice and video, as well as sources which have aggregate long-range dependent behavior. It is found that the proposed schemes, in comparison to packet GPS (PGPS), reduce packet losses and curtail the tails of delay distributions for real-time traffic and hence permit the use of significantly smaller playout buffers for the same network load.
