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.
A session relay apparatus for implementing communication between a transmission terminal and a reception terminal by relaying data between a first session established with respect to the transmission terminal and a second session established with respect to the reception terminal, comprising:
A session relay method of implementing communication between a transmission terminal and a reception terminal by relaying data between a first session established with respect to the transmission terminal and a second session established with respect to the reception terminal, comprising:
A session relay program which causes a computer to function as a session relay apparatus for implementing communication between a transmission terminal and a reception terminal by relaying data between a first session established with respect to the transmission terminal and a second session established with respect to the reception terminal, the program causing the computer to execute:
