  Although multicast communication, in interconnection networks has been a major avenue for a lot of research works found in literature, there are several key issues that should still be improved in order to meet the increasing demand for service quality in such systems. Apparently, most of the related works handle multicast communication within limited operating conditions such as low traffic load, specific network sizes and limited destination nodes. However, this paper investigates the multicast communication under different scenarios. It presents a comparison study of some well known multicast algorithms proposed for wormhole switched interconnection networks. Unlike the previous studies, this paper considers the multicast latency at both network and node levels. Performance evaluation results show that our proposed algorithm can greatly improve the performance of multicast operation.
