APPARATUS AND METHOD FOR MEASURING A BANDWIDTH FOR DATA TRANSMISSION BETWEEN COMMUNICATION DEVICES

摘要

An apparatus acquires a packet transmitted between a transmission-terminal and a reception-terminal, and stores the acquired packet in association with a time at which the packet has been acquired. When a first bandwidth of data packets transmitted by the transmission-terminal during a time-period from acquisition of a first ACK-packet transmitted by the reception-terminal to acquisition of a second ACK-packet transmitted by the reception-terminal subsequently to the first ACK-packet, is smaller than a second bandwidth or greater than a third bandwidth, the apparatus determines the second ACK-packet to be a packet not desired to measure a bandwidth, where the second bandwidth is calculated using an acquisition interval between first and second data packets transmitted respectively after waiting for the first and second ACK-packets, and the third bandwidth is calculated using an acquisition interval between two adjacent data packets including a data packet transmitted without waiting for an ACK-packet.

1. A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:
acquiring a packet which is transmitted between a transmission terminal and a reception terminal, at any spot of a network between the transmission terminal and the reception terminal; storing the acquired packet in association with a time at which the packet has been acquired; and when a first bandwidth of data packets which are transmitted by the transmission terminal during a time-period from acquisition of a first acknowledgement (ACK)-packet transmitted by the reception terminal to acquisition of a second ACK-packet that is transmitted by the reception terminal subsequently to the first ACK-packet, is smaller than a second bandwidth or greater than a third bandwidth, determining the second ACK-packet to be a packet which is not desired to measure a bandwidth, the second bandwidth being calculated using an acquisition interval between first and second data packets that are transmitted respectively after waiting for the first ACK-packet and the second ACK-packet, the third bandwidth being calculated using an acquisition interval between two adjacent data packets that includes a data packet transmitted without waiting for an ACK-packet.
