Group Communication Protocol for Autonomic Computing

We discuss a group communication protocol, which supports applications in change of QoS supported by networks and required by applications. An autonomic group protocol is realized by cooperation of multiple autonomous agents. Each agent autonomously takes a class of each protocol function. Classes taken by an agent are required to be consistent with but might be different from the others. We make clear what combination of classes can be autonomously taken by agents. We also present how to change retransmission ways
