摘要： A session relay apparatus includes a packet relay unit, session relay unit, storage unit, session state registration unit, and session state updating unit. Upon receiving a session initiation packet or an acknowledge packet to acknowledge the session initiation packet, the packet relay unit directly transmits the received packet to a transmission destination without rewriting the packet. The session relay unit terminates the session and relays data. The storage unit stores information of the session terminated by the session relay unit. The session state registration unit temporarily registers, in the storage unit, session information corresponding to the session whose establishment is requested upon receiving the session initiation packet. The session state updating unit defines the temporarily registered session information upon receiving the acknowledge packet. When the packet of the session with the defined session information is received, the session relay unit terminates the session and relays the data. A session relay method and a session relay program are also disclosed.

摘要： Communication allowance determination means determines, using information of a packet received by a packet relay unit and based on a policy which is information associating a match condition with communicability information, whether to allow or not to allow communication to a destination unit for the packet that meets the match condition, the match condition being information identifying the packet, and the communicability information indicating whether to allow or not to allow the communication to the destination unit for the packet that meets the match condition. Rule setting means sets, at least in the packet relay unit receiving the packet, a rule of executing a process for suppressing forwarding of the packet to the destination unit, on condition that the communication allowance determination means determines not to allow the communication to the destination unit for the packet that meets the match condition.

First control device among the control devices, in response to a predetermined trigger, refers to correspondence between forwarding nodes and control devices, and transmits, among forwarding path information, at least forwarding path information that includes a forwarding node associated with the first control device, to second control device associated with a forwarding node that is not associated with first control device, among forwarding nodes on a forwarding path of the received packet. Second control device generates and sends the processing rule to a forwarding node on the forwarding path, among forwarding nodes associated with the second control device, based on the forwarding path information.

摘要： A communication system includes a plurality of nodes and a control device. Each node includes a packet processor that processes a packet in accordance with a processing rule when the packet is received. The processing rule correlates the processing applied to the packet with a matching rule that identifies the packet the processing is to be applied to. The control device calculates a packet forwarding path in response to a request for setting processing rules from any node, sets processing rules that implement the packet forwarding path on the node on the packet forwarding path and records the processing rules in a manner coordinated with one another. The control device inquires at the node on the packet forwarding path about state of setting of processing rule and, upon detecting failure in the processing rule set in at least one node, executes rollback operation on the correlated processing rules set in other node.
