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.

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： When a failure occurs in a link or another relay device, a route control unit updates a routing table stored in a current routing table. Upon update, it acquires inhibit target route information indicating a route likely to cause a micro-loop in the updated routing table and registers it into an inhibit target table. If route update in an adjacent relay device is completed, an inhibit control unit deletes a route in which the adjacent relay device is set as a next transfer destination from the inhibit target table. A transfer processing unit determines a transfer route of a packet based on the current routing table and, if the determined transfer route is not registered in the inhibit target table, executes transfer of the packet. A micro-loop can be thereby reliably avoided when route switching in a network system where communication between plural networks is relayed by plural relay devices.
