COMMUNICATION PATH CONTROL SYSTEM, PATH CONTROL DEVICE, COMMUNICATION PATH CONTROL METHOD, AND PATH CONTROL PROGRAM

摘要

A communication path control system that can reduce the number of packets used for communication path control is provided. Process querying means in a packet transmitting device queries a path control device about a process for a received packet. When receiving the query about the process for the packet from the packet transmitting device, packet transmitting device determining means in the path control device determines a packet transmitting device that is applied a packet transmission rule determined according to the packet, based on whether or not the query about the process for the packet is a first-time query.
