Network configuration investigating device, network configuration investigating program, network configuration management method, and network configuration management system

摘要

A network configuration management method has a step of sequentially propagating a network ticket that a network configuration monitoring node has issued to each of a predetermined number of nodes (predetermined number of nodesnumber of all nodes) from the node to the node so as to cover all nodes of a P2P network, a step in which each of the nodes having received the network ticket plays a role to investigate the node adjacent to its own node, creates information on a network configuration around its own node, and transmits the information on the network configuration created by each of the nodes to the network configuration monitoring node. Furthermore, in the network configuration management method, the network configuration monitoring node grasps the configuration of the entire P2P network from the collected information on the network configuration.
