Abstract
A communications network control system includes a packet judging circuit for judging whether a variable-length packet inputted via a network is a control packet CPKT self-addressed and containing control information for network control, or a transfer packet TPKT that should be transferred to other addresses, and a control information management circuit for receiving the control packet judged to be the control packet by the judging circuit via the network, and managing and processing the control information, based on the received control packet. This system further includes a routing table management circuit for storing the control information transmitted to the network from the management circuit in such a way that the control information can be updated as well as for controlling a transfer of the transfer packet, and a packet rewriting circuit for executing a process of rewriting contents of the transfer packet in accordance with the control information stored in the table management circuit in parallel with a process of the control packet by the information management circuit in order to transfer to another network the transfer packet judged to be the transfer packet by the judging circuit.
