SESSION RELAY DEVICE AND RELAY METHOD

摘要

A session identification unit (11) determines a session to which an arrived packet belongs, and session relay units (12-1 to 12-N) perform relay processing between a session with a sending terminal and a session with a receiving terminal. A packet scheduler (13) issues an instruction to control the output of packets from the session relay units (12-1 to12-N), and an output control unit (14) outputs packets from the session relay units (12-1 to 12-N) according to the instruction. In the session relay unit (12-1), a sending session processing unit (121-1) processes a session for sending data to the receiving terminal, and a sending buffer (122-1) stores received data until the sending of the data ends. A receiving session processing unit (123-1) process a session for receiving data from the sending terminal.
