摘要： A communication system includes a plurality of terminals and a server that relays packet data transmitted and received between a first terminal and a second terminal among the plurality of terminals. The server includes a connection establishment message processing unit configured to transmit a first SYN ACK message that is a response message to a first SYN message transmitted from the first terminal for establishing a TCP connection upon receiving the first SYN message from the first terminal, and an option information notifying unit configured to transmit a first TCP option information notifying message that includes first TCP option information included in the first SYN message from the first terminal and first communication destination information to indicate the second terminal as a destination of communication. The first terminal recognizes the second terminal as the destination of communication and notifies the second terminal of the first TCP option information included in the first TCP option information notifying message, upon receiving the first TCP option information notifying message from the option information notifying unit.

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.

摘要： A communication system comprises control devices, and forwarding nodes each includes packet processing unit that performs processing of a received packet based on a processing rule set in advance or received from control device associated with the node. 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 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.
