Multi-destination communication in broadcast WDM networks: a survey

摘要

In this paper we survey protocols and scheduling algorithms designed to transport multi-destination traffic in broadcast WDM networks. The protocols are classified based on the underlying strategy used to transmit multicast packets, as well as on their assumptions regarding the network architecture. A number of approaches for scheduling both single- and multi-destination traffic are also described and discussed. We discuss the advantages and disadvantages of each scheme, and we also identify the regions of network operation for which each strategy is most appropriate.
