Performance Comparison and Analysis of Manycast QoS Routing Algorithm Over Optical Burst Switched Networks

In network communications, there are many methods to deliver data from sources to destinations. During the past few years, the authors have observed the emergence of new applications that use multicast transmission. In many distributed applications require a group of destinations to be coordinated with a single source. Multicasting is a communication paradigm to implement these distributed applications. However in multicasting, if at least one of the members in the group cannot satisfy the service requirement of the application, the multicast request is said to be blocked. On the contrary in many-casting, destinations can join or leave the group, depending on whether it satisfies the service requirement or not.
