Abstract :
A two-node asynchronous transfer mode (ATM) network is considered. Several video sources are assumed multiplexed at the source node. Five alternative algorithms for bandwidth allocation to video sources are considered using: static-slot assignment, buffer-population-based dynamic slot assignment, first-come-first-serve slot assignment and rate-based dynamic slot assignment. The average cell delay and the coefficient of variation of the delay for the five algorithms are determined by computer simulation and compared. It is concluded that the adaptive slot assignment algorithm and the buffer-population-based dynamic slot assignment algorithm are suitable for packet video in ATM networks
