    摘要： A router includes a label-mapping-message receiving unit, a passing-node managing unit, and a passing-node selecting unit. The label-mapping-message receiving unit receives a label-mapping message including label information and PV TLV information from all adjacent nodes. The passing-node managing unit registers received label information and PV TLV information to manage the information. When a line fault occurs in a network, the passing-node selecting unit selects PV TLV information that does not include an identifier of the router itself from among registered PV TLV information. Thus, an optimal path is determined based on selected PV TLV information so that a loop does not occur in the network.

    摘要： A secure data communications system with an enhanced function of preventing information leakage. The system includes a user terminal and a router. The router has a security condition definition unit and a storage unit to receive and store a set of security conditions. A packet parser identifies and parses a packet produced by a file transfer application protocol and extracts from that packet a destination address and a security condition ID that the sending user has specified for a file in the packet. The packet parser discards the packet to prevent information leakage if the extracted destination address does not satisfy the security condition corresponding to the user-specified security condition ID. The user terminal has a security condition user interface that requests the router to provide information about security conditions and gives a security condition ID to each file to indicate which security condition the sending user has specified.

    摘要： A filter-information transmitting/receiving unit transmits path information with the filter information when the filter information is set by a filter setting unit, and receives the path information when the filter information is set in other network device. A filter-combining determining unit determines whether redundant filter information with the other network device is to be combined or deleted, based on the filter information and the path information. A filter control unit issues a filter-setting request or a filter release request based on a result of determination by the filter-combining determining unit.
