Abstract:
1. A packet transmission control device, comprising: a socket detecting system that detects addresses and ports of a first device and a second device, which perform a packet communication in a network by transmitting/receiving data packets; a socket storing system that stores addresses and ports detected by the socket detecting system; a session information detecting system that detects session information regarding the packet communication according to a communication protocol of the packet communication between the first device and the second device; a session information storing system that stores the session information detected by the session information detecting system; a terminal capability detecting system that detects terminal capability of each of the first device and the second device prior to the packet communication according to the communication protocol; a terminal capability storing system that stores the terminal capabilities detected by the terminal capability detecting system; a tentative connection system that executes a connecting proceeding with a third device when the first device and the second device is executing the packet communication according to the communication protocol, the connecting proceeding with the third device being performed according to the communication protocol, the session information stored in the session information storing system and the terminal capabilities stored in the terminal capability storing system; and an interruption system that realize a communication between the first device and the third device by transferring a packet, which is transmitted by the third device toward the tentative connection system, to the first device, and a packet, which is transmitted by the first device toward the second device, to the third device, in accordance with the addresses and ports stored in the socket storing system.
