    摘要: A datagram relaying apparatus includes a plurality of protocol terminating units, and a destination determining processor. The destination determining processor includes a path selecting section which determines a transfer destination route for a stream of packets received from any of the protocol terminating units. The path selecting section determines whether or not transfer of the received stream of packets to the transfer destination route is in an inhibition state, and selects another transfer destination route when the transfer of the packet to the transfer destination route is in the inhibition state.

    摘要: A communication control apparatus includes an input and output unit responsive to reception of a packet, for generating a search request and a destination address of the packet to receive a resultant route data, and for transmitting the packet based on the resultant route data. A memory stores a route tree table having a tree structure of a plurality of nodes, each of which has a node data. A route searching circuit refers to the route tree table in response to the search request to determine a route data of a final node data as the resultant route data from the destination address, and outputs the resultant route to the input and output unit.

    摘要: A layer 1 frame, capable of accommodating data of any protocol selected from an STM (Synchronous Transfer Mode) signal, ATM (Asynchronous Transfer Mode) cells, a primary IP (Internet Protocol) packet and a best effort IP packet in a common frame format, is constructed by an edge node and transmitted to a data transfer system composed of edge nodes, core nodes, etc. The layer 1 frame includes a layer 1 frame header, a layer 1 frame payload and a payload CRC (Cyclic Redundancy Check) field. The layer 1 frame header includes a “Packet Length” identifier, a “Priority” identifier, a “Protocol” identifier indicating the type of the data, a “Frame Mode” identifier, a “Stuff” identifier indicating whether or not stuff data is contained in the layer 1 frame, and a “Header CRC” identifier. The layer 1 frame payload contains a layer 2 frame having a layer 2 frame header and a layer 2 frame payload in which the data is packed. STM layer 1 frames containing the STM signals are transferred with the highest priority at fixed intervals (125 μsec). Best effort IP layer 1 frames containing the best effort IP packets are transferred with the lowest priority. Partitioning of the best effort IP layer 1 frame, stuffing, dummy frames, etc. are employed for implementing the periodical transmission of the STM layer 1 frames.

    摘要: A caching method for caching network contents of a packet transfer network including a packet relay for relaying accesses of clients to servers supplying contents, and a network contents cache device are disclosed. Accesses from the clients to the servers are monitored by the said packet relay to determine a cache priority on the basis of a product of relaying path lengths from the packet relay to the server and frequency of access from the client to the servers and the network contents cache device preferentially caches a response to the access to the server having higher cache priority.
