Group Communication

Within each member process, the group library connects to the group server. While connected, the member and the group server exchange periodic protocol messages. When disconnected, the member initiates reconnection.

To reduce the cost and complexity of this required communication, resulting in best performance, run the group server and all group members in nearby geographical proximity to one another.

Group protocol communication depends on application definitions that define endpoints, on transports that connect members to the group server, and on the formats of group protocol messages.
