INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

An information terminal 10B receives plural UDP packets each having a predetermined data size and sequentially transmitted at a predetermined time interval in a predetermined order; extracts pairs of the UDP packets, in which each of a transmission order and a reception order is continuous and the transmission order and the reception order match with each other, from among the received UDP packets; calculates an evaluation value for evaluation of a delay state of a communication path between an information terminal 10A and the information terminal 10B based on comparison between a reception time interval of the packets in each of the extracted pairs of the UDP packets and the predetermined time interval; and judges whether a bit rate of the UDP packets is available or unavailable based on comparison between the calculated evaluation value and a threshold.

主权项

1. An information processing system comprising:
a first apparatus and a second apparatus, wherein the first apparatus includes
a transmitting unit that sequentially transmits a plurality of UDP packets each having a predetermined data size to the second apparatus at a predetermined time interval in a predetermined order, and wherein the second apparatus includes
a receiving unit that receives the UDP packets sequentially transmitted by the transmitting unit,an extracting unit that extracts pairs of the UDP packets, in which each of a transmission order and a reception order is continuous and the transmission order and the reception order match with each other, from among the UDP packets received by the receiving unit,a calculating unit that calculates an evaluation value for evaluation of a delay state of a communication path between the first apparatus and the second apparatus based on comparison between a reception time interval of the packets in each of the pairs of the UDP packets extracted by the extracting unit and the predetermined time interval, anda judging unit that judges whether a bandwidth of a bit rate, which is calculated in accordance with the predetermined data size and the predetermined time interval based on comparison between the evaluation value calculated by the calculating unit and a threshold, is available or unavailable for communication between the first apparatus and the second apparatus.
