    摘要: A communications network control system includes a packet judging circuit 412 for judging whether a variable-length packet inputted via a network 12 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 512 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 413 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 414 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 13 the transfer packet judged to be the transfer packet by the judging circuit.

    摘要: When service is allocated to a server of the other network on the basis of load information, a packet from a client is transferred as a transfer packet to the other wide area load distribution apparatus. The other wide area load distribution apparatus fetches the client packet from the transfer packet and converts its destination from a transferor address Lx to a server address S and its sender from a client address C to a self address Ly for sending to a server. Upon a reception of a response server packet from the server, the destination is converted from the self address Ly to the client address C and the sender is converted from the server address S to the transferor address Lx for the relay to the client.

    摘要: This invention provides highly thermally stable trehalose phosphorylases. The trehalose phosphorylases of the present invention can be obtained from cultured mixture of microorganisms and are highly thermally stable, and produce .alpha.-D-glucose 1-phosphate and D-glucose by an action on trehalose and an inorganic phosphoric acid or salt thereof, or trehalose by an action on .alpha.-D-glucose 1-phosphate and D-glucose. This invention also relates to the process for the preparation of trehalose phosphorylase, and trehalose or .alpha.-D-glucose 1-phosphate with said trehalose phosphorylase.
