摘要： A network environment capable of performing a smooth and comfortable TCP session operation is provided to a user. The session relay equipment includes a bridge portion which relays a session by which a sequence of packets are transmitted and received between terminals connected with each other via a network; a socket information table which has socket information containing (1) address information of the terminal and (2) protocol information used in the session, the socket information being associated with information on whether or not the session is to be terminated; and a service information table which has information on a communication service to be provided for each service provision unit, the communication service being identified based on predetermined information within a header of the packet. The bridge portion terminates the session and executes a communication service based on the information contained in the header of the packet and the socket information.

摘要： Bandwidth control unit (123-1) controls data transfer from reception buffer (122-1) to transmission buffer (124-1). Transmission resumption ACK generation unit (126-1) generates an ACK packet instructing a transmission terminal to resume transmission while duplicate ACK generation unit (127-1) generates a duplicate ACK instructing the transmission terminal to reduce the transmission rate. Packet discarding ratio calculation unit (128-1) obtains a packet discarding ratio in a session to a reception terminal. According to a data amount remaining in the transmission buffer and the packet discarding ratio, control parameter calculation unit (129-1) changes the control parameter of the session to the reception terminal.

In a pair of an active information processing device and a standby information processing device closest to a transmitting terminal in the information processing system, the standby information processing device is arranged closer to the transmitting terminal. In a pair of an active information processing device and a standby information processing device closest to a receiving terminal in the information processing system, the standby information processing device is arranged closer to the receiving terminal. In other pair, a standby information processing device can be arranged closer to either the transmitting terminal or the receiving terminal.

摘要： A session identification unit (11) determines a session to which an incoming packet belongs, while a session relay unit (12-1-12-N) relays between a session with a transmission terminal and a session with a reception terminal. A packet scheduler (13) instructs and controls the delivery of packets from each session relay unit (12-1-12-N), and a delivery control unit (14) delivers packets from each session relay unit (12-1-12-N) based on the instruction. In the session relay unit (12-1), a transmission session processing unit (121-1) processes a session for transmitting data to the reception terminal, and a transmission buffer (122-1) stores received data until the end of a transmission. A reception session processing unit (123-1) processes a session for receiving data from the transmission terminal.

摘要： A communication apparatus includes an arrival time estimation unit, connection selection unit, and network processing unit. The arrival time estimation unit estimates, for each block and each of a plurality of connections, an arrival time until a block generated by segmenting transmission data arrives from the apparatus at a final reception terminal or a merging apparatus through a network. The connection selection unit selects, for each block, a connection with the shortest arrival time from the plurality of connections on the basis of the estimation result. The network processing unit outputs each block to the network by using the selected connection. A data communication method and a data communication program are also disclosed.
