Abstract: PROBLEM TO BE SOLVED: To provide a topology transmission mechanism that allows various nodes under a distributed computing environment for maintaining a common network topology database. SOLUTION: Transmission of a group connection relation message is stopped for a period, when no topology is changed in the distributed computing environment. When at least one group leader confirms a change in at least one topology in the distributed computing environment, the group leader restarts transmission of the group connection relation message. A node (node 2), which is common to both node groups on a 1st network and a 2nd network, is employed to transfer the group connection relation message, from the group of nodes on the 1st network to the group of other nodes over the 2nd network.
