SESSION RELAY DEVICE AND RELAY METHOD

摘要

A band control section (123-1) controls data transfer from a reception buffer (122-1) to a transmission buffer (124-1). A transmission resumption ACK generation section (126-1) generates an ACK packet instructing a transmission terminal to resume transmission while a duplicate ACK generation section (127-1) generates a duplicate ACK instructing the transmission terminal to reduce the transmission rate. A packet discarding ratio calculation section (128-1) calculates a packet discarding ratio in a session to a reception terminal. According to a data amount remaining in a transmission buffer and the packet discarding ratio, a control parameter calculation section (129-1) modifies the control parameter of the session to the reception terminal.
