摘要： An electrical connector includes a housing and terminals made of a sheet metal, which are held by the housing. The plurality of terminals is arranged in a direction perpendicular to a contact surface of a contact section thereof, and is held by the housing. Each of the terminals has a held section to be held by the housing, a contact section to contact with a mating terminal, and a connecting section to be connected to a circuit board each forming a flat sheet surface. The contact section is formed to have a flat contact surface, which slidably contacts with the mating terminal and extends in a connector fitting direction.

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.

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.

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.
