Causally ordered delivery of multimedia objects
In distributed applications such as teleconferences, a group of multiple processes are cooperating, where messages exchanged among the processes are required to be causally delivered. The processes are exchanging kinds of multimedia objects in addition to traditional text data. Since the multimedia messages are longer than traditional messages and are structured, it takes such a longer time that a communication event cannot be considered to be atomic. In this paper, we discuss new types of causally precedent relations among multimedia objects transmitted in the network. We discuss a protocol to causally deliver multimedia objects in a group of multiple processes. We also show the evaluation of the protocol. (C) 2002 Elsevier Science B.V. All rights reserved.
