Abstract

A system for scheduling multicast packets through an interconnection network, comprising r1 input ports (110) with each input port having r2 input queues (171), r2 output ports (120) with each output port having r1 output queues (181), and the interconnection network having a speedup of at least s = 2 x r1+ r2-1/MAX (r1, r2) 3 with s subnetworks, each subnetwork comprising at least one first internal link connected to each input port for a total of at least r1 first internal link, each subnetwork further comprising at least one second internal link connected to each output port for a total of at least r2 second internal links is operated in strictly nonblocking manner in accordance with the invention by scheduling, at most r1 packets in each switching time be switched in at most r2 switching times when r1 r2, and at most r2 packets in each switching time to be switched in at most r1 switching times when r2 r1, in deterministic manner, and without the requirement of segmentation and reassembly of packets.
