Wide-area Group Communication Protocols : International Experiment

Description

In distributed applications like teleconferences, a group of multiple processes is first established and then the processes in the group are cooperated. Group communication protocols support a group of the processes with the reliable and ordered delivery of messages to multiple destinations. The group communication protocols discussed so far assume that every pair of processes support almost the same delay time and reliability. That is, only processes in a local area are cooperated. High-speed group communication among multiple processes distributed in a wide area is required to realize the world-wide multimedia applications. In the Internet, it takes about 60 msec to propagate a message in Japan while taking about 240 msec between Tokyo and Europe. Over than 10% of the messages are lost between Japan and Europe while less than 1% are lost in Japan. Thus, it is essential to consider a wide-area group of processes where the delay times and reliability levels between the processes are significantly different. In the wide-area group, the time for delivering messages to the destinations is dominated by the longest delay between the processes.
