Abstract: A group communication system is designed for meeting requirement of large-scale computation task. After describing system framework, it brings forward to the reliable message-passing protocol and membership management protocol. The message-passing protocol can guarantee the reliability of message-passing, even if an agent is mobile, the message will arrive destination. The membership management protocol guarantees the flexibility and expansibility of membership management. What’s more, it can meet the need of the integrity and accuracy of fault detecting and low net load.

Key words: mobile Agent, group communication, reliability
