Protocol for synchronizing multimedia objects exchanged in a group of processes

In distributed applications, a group of multiple processes are cooperating where multimedia messages are exchanged among the processes. The multimedia objects are longer than traditional messages and are structured. If messages transmitted in a network are causally delivered by using traditional group protocols, computation and communication overheads are increased due to the large size of multimedia data. In this paper, we discuss new types of causally precedent relations among multimedia objects transmitted in a group of multiple processes. We discuss a protocol to causally deliver multimedia objects in a group of processes.
