摘要： To eliminate interruption of a service used by a user and reset of communication caused by switching of an operating server such as a process migration or the like. On receiving a session migration start request, server/network cooperation control means 2 issues an operating server-switching control start notification to an operating server switching control means 3 (step S702). On receiving the operating server switching control start notification, the operating server switching control means 3 switches an operating server. Next, on receiving an operating server switching control completion notification, the server/network cooperation control means 2 sends a connection destination target network-switching request to a connection control means 4 (step S707). The connection control means 4 switches the connection destination target network of the user corresponding to a user name whose connection destination target network is to be switched, from a target network including a main server to a switch destination target network including a backup server (step S708).

摘要： A DNS Proxy unit (A12a) holds the domain name of an encrypted communication target node in a CUG setting table (A125a), intercepts a name resolution request for a communication partner node output from an application (A11x) to a DNS server (B1a), determines by looking up the CUG setting table (A125a) whether the communication partner is an encrypted communication target node, and if the communication partner is an encrypted communication target node, registers the IP address of the name-resolved communication partner in an encrypted communication path setting table (A142a). A data packet sent from the application (A11x) to the IP address is intercepted by a data transmission/reception unit (A14a). A data packet to an IP address registered in the encrypted communication path setting table (A142a) is encrypted by a communication encryption unit (A141a) and transmitted to the communication partner. In this way, in executing encrypted communication with a plurality of communication partners by using a communication encryption function provided by an OS, setting of the encrypted communication target node can be done by using a domain name.

摘要： When a packet transfer equipment receives a packet, it extracts several types of information contained in the received packet such as the destination IP address and the destination port number and, using the extracted information as the key, inquires of a packet transfer method resolution server about the information related to the packet transfer method. The server keeps the correspondences between several types of information contained in the packet and one or more type of information related to the packet transfer method in the database and, in response to the inquiry from the packet transfer equipment, replies one or more type of information related to the packet transfer method. The packet transfer equipment rewrites several types of information such as the destination IP address and the destination port number according to one or more type of information obtained and transfers the received packet.

摘要： A VPN gateway (A11) includes a WAN interface (A111) for exchanging packets with client nodes (C1, C2, D1, D2) via IPsec tunnels (B11-B14) set on the WAN side, a LAN interface (A112) for exchanging packets with server nodes (A131-A136) connected to the LAN side, a session relay unit (A114) for temporarily terminating a first communication session to be set for a sever node from a client node, and setting a second communication session that relays the first communication session to the server node, and an SSL processor (A116) for making the second communication session into an SSL. This arrangement makes it possible to dynamically allocate the servers in a data center (A1) to a VPN, permit only an authenticated server to communicate with another node in the VPN, and prevent wiretapping and tampering of communication performed by the server.

摘要： A router has a network topology table and a number of resource tables corresponding to network areas. In response to a user's request, one of entries of the topology table and one of the resource tables are referenced and a traversable area along the route to the destination and links of the area which satisfy a user-specified QoS value are selected. A calculation is performed on the selected links according to the Dijkstra algorithm to find a shortest path to the destination if the referenced entry indicates that the destination is in the local area of the router. If the entry indicates otherwise, the calculation is continued until a shortest path tree is found for all area border routers of the traversable area or until the calculation terminates if that tree is not found for all such routers, and a route having an optimum QoS value is determined from the shortest path tree.

摘要： There is provided a communication delay time derivation method for calculating a communication delay time depending on a combination of channels set between communication terminals on a communication path in the MCH/IF environment. When selecting a channel to be used for communication in each section on the communication path per section between communication terminals on the communication path, a calculation target section specification means 82 detects an inter-terminal selected channel repetitive pattern as a pattern of the selected channels cyclically appearing on the communication path, and defines a section corresponding to the inter-terminal selected channel repetitive pattern as a communication delay time calculation target section. A communication delay time derivation means 83 derives a communication delay time in the calculation target section based on the inter-terminal selected channel repetitive pattern.
