Abstract :
A multicast switching architecture called a duplex multicast switch is proposed, and several switch control algorithms are developed. A duplex multicast switch, with two point-to-point routing nets, has potential to provide significantly better performance than a simplex multicast switch by reducing the output loadings of routing nets. To fully realize its potential, two call distribution algorithms, cluster distribution and spread distribution, are developed. Cluster distribution is partitioned into partial search cluster distribution and exhaustive search cluster distribution based on search policies, and the performance of the three algorithms is analyzed by the arrival modulation technique. The results show that a spread distribution eliminates most slot contention blocking and achieves near-optimal performance
