摘要： An active router and standby routers share routing information used for dynamic routing while in normal operation. Further, the active router and the standby routers share routing information obtained after route computation is performed according to a routing protocol. Thus, efficient operation can be achieved. Protocol engines (31a to 31d) communicate with routers (41 and 42) to compute a route to be selected for routing with respect to a corresponding protocol. When the routing information has changed, a shared routing information transmitter (33) transmits the routing information and the like to the standby routers. Each of the protocol engines in a router operating as an active router communicates with the routers (41 and 42) to compute a route to be selected for routing with respect to a corresponding protocol. When the routing information has changed, a shared routing information receiver (34) receives the routing information and the like transmitted from the protocol engine.

摘要： Distribution processing control unit determines a main processing range and a sub-processing range whose charges are taken by a cluster member to which the unit belongs. Among packets multicast to a cluster system, a filter hands over packets matching with the main processing range and the sub-processing range to a session processing unit. The session processing unit conducts session processing (including processing of updating session information stored in a holding unit). Thereafter, when the packet matches with the main processing range, the session processing unit hands the packet over to a packet forwarding unit and when the packet matches with the sub-processing range, abandons the packet. When a cluster member in charge of main processing of a packet whose sub-processing is taken charge of by the cluster member in question develops a failure, a failure recovery unit changes the sub-processing range to the main processing range.

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： A router (1) introduces virtual interfaces (3-1-3-n) between network interfaces (2-1-2-n) and a routing processing unit (4). The virtual interfaces (3-1-3-n) function to conceal a state such as a hit of the network interfaces (2-1-2-n) from the routing processing unit (4). One virtual interface is provided for each of the network interfaces (2-1-2-n). In the virtual interfaces (3-1-3-n), an up state, a down state, and a hit state are prepared as the states which the link takes. In the case of the hit state, the virtual interfaces (3-1-3-n) do not notify the routing processing unit (4) of a change in link state.
