    摘要: A packet transfer scheme in a network system capable of realizing a high speed, large capacity inter-network communication under an internet environment. A network interconnection apparatus (router) has a memory for storing a correspondence relationship between a virtual connection used in receiving a packet from one logical network and a virtual connection used in transmitting a packet to another logical network, and a transfer at a datalink layer is carried out according to the registered correspondence relationship, to effectively form a bypass pipe capable of transferring a packet by an datalink layer level processing alone over a plurality of networks from the transmission terminal to the destination terminal, so that a high speed packet transfer between networks can be realized.

    摘要: An acquiring unit acquires a first search criterion from outside. A first searching unit extracts a first search result that satisfies the first search criterion from a storing unit that stores information to be searched. A first output unit outputs the first search result to a first output device. A changing unit changes the first search criterion to a second search criterion based on a predetermined condition. A second searching unit extracts a second search result that satisfies the second search criterion from the storing unit. A second output unit outputs the second search result to a second output device that is different from the first output device.

    摘要: A packet transfer scheme for transferring packets at a boundary of a plurality networks is disclosed. A network interconnection apparatus (router) communicates with a previous hop node in one of the plurality of networks by a first control message including a first identification information for identifying an upstream path from the previous hop node and a specification information for specifying a group of packets to be transferred on the upstream path, and with a next hop node in another of the plurality of networks by a second control message including a second identification information for identifying a downstream path to the next hop node and a specification information for specifying a group of packets to be transferred on the downstream path. Then, the network interconnection apparatus stores a first identifier at a layer lower than layer 3 of the upstream path and a second identifier at a layer lower than layer 3 of the downstream path corresponding to the upstream path, according to the first and second control messages, and transfers a packet from the upstream path to the corresponding downstream path, referring to the memory.
