    摘要： A path control method includes a procedure for developing a path control message including regional information in transmission on the network. The regional information designates a path and/or a path length for transmitting the path control message. The path control message includes a regional property for instructing each node as to how to process the regional information either in a strict manner or in a flexible manner. With reference to the regional information and/or the regional property, each node is capable of selecting a destination node to which the path control message is to be transmitted, stopping the further transmission of the path control message, or discarding the path control message.

    摘要： The processing load of a path control message on a node due to a link fault is reduced, a normal routing operation is assured, and the stable continuity of a network is realized. The node having received the path control message transmits the path control message to the adjacent node having transmitted the path control message and at least one or more adjacent nodes on an alternate path.

    摘要： A wireless multi-hop network communication terminal 11 uses a Hello information suppression function 21 to suppress a part of information included in a Hello message for a given time after start-up or a new neighbor terminal is detected, thereby reducing message length. Further, the communication terminal 11 uses a Hello interval adjustment function 22 to adjust and shorten a Hello interval during the suppression of the Hello message length. After canceling the suppression of the Hello message length, the communication terminal 11 calculates and establishes a second Hello interval that is shorter than the usual one. Furthermore, after canceling the second Hello interval, the communication terminal 11 reestablishes the steady-state Hello interval. In this way, the time required for the route convergence among the communication terminals can be shortened when a large number of communication terminals, which are adjacent to one another in a narrow-band wireless network and existent within a wireless communication range, are started up at the same time or when a new communication terminal is added to the network.

    摘要： A data transmission system includes a plurality of dynamic route control units each disposed for one of a plurality of interfaces provided in the data transmission system. The route control data prepared by the dynamic route control units are combined by a specified dynamic route control unit to obtain in-system route control data, which is delivered to all the dynamic route control units. Each dynamic route control unit calculates costs for the routes between the own system and other data transmission systems based on the in-system route control data and new route control data received.

    摘要： A multicast packet transfer system includes a first packet transfer apparatus and a second packet transfer apparatus. The first packet transfer apparatus transmits transfer packet data relating to an IP header and a UDP header of a multicast packet when the multicast packet is received, rewrites a header section of the multicast packet to produce a unicast packet, and transmits the unicast packet. The second packet transfer apparatus receives the transfer packet data and the unicast packet, and reproduces the multicast packet based on the received unicast packet and the received transfer packet data.
