NETWORK AVAILABLE BANDWIDTH HIGH-SPEED MEASUREMENT METHOD AND TRANSMISSION DELAY TREND MEASUREMENT APPARATUS

摘要

PURPOSE: A method for measuring a network available bandwidth in high speed and a device for measuring transmission delay tendency are provided to make measurement traffic not interfere an original media by using a duplicated packet of the original media as a measuring traffic. CONSTITUTION: A transmitting party transmits a media to a receiving party(510). The receiving party collects time interval between the packets of the transmitted media(520). The receiving party inspects one-way delay related to the packet based on the collected time interval(530). The receiving party reports the inspected one-way delay to the transmitting party(540). The transmitting party controls a bit rate of the media based on the reported one-way delay(550).
