Abstract: A communication system couples a first communication network including a data transfer apparatus and a second communication network including a router to each other. The first communication network is constructed by centralized control by the network control computer. The second communication network is constructed by autonomous distributed control by using a protocol on an IP layer of the router. The router transmits protocol data requiring protocol processing on the IP layer to the data transfer apparatus. The data transfer apparatus transfers the protocol data from the router to the protocol processing computer. The protocol processing computer being configured to: carry out, when receiving the protocol data, the protocol processing on the IP layer for the received protocol data; and hold identification information on an interface included in the data transfer apparatus for transferring the protocol data to the protocol processing computer.
