Abstract :
A model for the analysis of ATM switches based on shared buffer switching for broadband ISDN networks is developed, and the results are compared with simulation. Switches constructed from shared buffer switching elements (SE) no longer suffer from the head of line blocking which is a common problem in simple input buffering. The analysis models the state of the entire switch and extends the model introduced by Turner (see International Teletraffic Congress, Copenhagen, Denmark, p.35-40, June 1991) to global flow control with a backpressure mechanism. It is shown that the buffer utilization is better and the throughput improves significantly compared with the same network using a local flow control policy
