A simple theory of traffic and resource allocation in ATM
Steven H. Low, Pravin P. Varaiya · 2002
The authors propose a simple framework to study the tradeoffs between bandwidth and buffer in an asynchronous transfer mode (ATM) network. Traffic is modeled as a deterministic fluid. The key concept is the burstiness curve b( mu ) which gives, for a connection, the maximum number b( mu ) of cells that must be buffered if the connection is served at a fixed rate of mu cells per second. Two popular service disciplines, the fixed rate discipline and the leaky bucket discipline, are shown to be burst reducing. The characterization of a class of practical service disciplines that are burst reducing is obtained. The tradeoffs between buffer and bandwidth along a connection and the options for resource allocation among simultaneous connections are considered.>
