The provider network that interconnects user networks includes a plurality of edge routers. At least one of the plurality of edge routers includes an obtaining unit for obtaining information of a packet transferred by the edge router itself, a creating unit for creating a flow list in which flow information of packets transferred from the user network side to the provider network side is registered based on the packet information, a monitoring unit for monitoring a traffic state of a flow of each packet registered in the flow list based on information of packets transferred from the provider network to the user network, and a notifying unit for notifying the traffic state of the flow registered in the flow list to a maintenance engineer.

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.

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.

In the presence information management method of the present invention, the e-mail address of the user and the terminal address of a terminal are extracted upon receipt of an e-mail transmission request, the e-mail address and terminal address correspondence table is retrieved by using the extracted e-mail address, and the extracted terminal address is registered in the e-mail address and terminal address correspondence table if the retrieved terminal address does not correspond to the extracted terminal address. Thus, the user can automatically update presence information with his/her e-mail transmission request.

A portable terminal apparatus includes a first enclosure, a second enclosure, and a control unit. The second enclosure takes modified forms including a first form and a second form. The second enclosure is closed over the first enclosure in the case of the first form. The second enclosure is separated from the first enclosure in the case of the second form. In the case of the first form, the control unit controls communication to be performed between the first enclosure and the second enclosure via a contact between the first enclosure and the second enclosure. In the case of the second form, the control unit controls communication to be performed between the first enclosure and the second enclosure by a radio communication unit.

摘要:
A terminal infected by an e-mail with a new virus is identified by storing information of e-mails as mail archive information, storing a distribution request history in which each distribution request of an email is associated with a terminal identification information which serves as a terminal information for identifying the terminal that has issued the distribution request, checking the mail archive and identifying an e-mail with a new virus, when definitions of new viruses have been added in a virus definition file, obtaining account information of the identified e-mail with the new virus, and extracting the terminal identification information of the terminal that issued the distribution request of the e-mail with the new virus, based upon both the obtained account information and the distribution request history.
