Information processing system, information processing apparatus, and non-transitory computer readable medium

An information processing apparatus comprising:

• a receiving unit that successively receives a plurality of packets that configure distribution data from an information distribution apparatus;
• a first judging unit that judges whether or not congestion occurs in communication with the information distribution apparatus, based on a change in time interval from transmission to reception of each of the packets successively received by the receiving unit;
• a second judging unit that judges whether or not a packet loss rate, which is a rate of a loss packet corresponding to a loss included in the packets transmitted from the information distribution apparatus and calculated based on the packets successively received by the receiving unit, is increased as compared with a value obtained by multiplying a packet loss rate before the packets that configure the distribution data are received, by a predetermined weight;
• and
• a requesting unit that requests the information distribution apparatus to change a bit rate of the packets that configure the distribution data, based on a judgment result by the first judging unit and a judgment result by the second judging unit.

A non-transitory computer readable medium storing a program causing a computer to function as:

• a receiving unit that successively receives a plurality of packets that configure distribution data from an information distribution apparatus;
• a first judging unit that judges whether or not congestion occurs in communication with the information distribution apparatus, based on a change in time interval from transmission to reception of each of the packets successively received by the receiving unit;
• a second judging unit that judges whether or not a packet loss rate, which is a rate of a loss packet corresponding to a loss included in the packets transmitted from the information distribution apparatus and calculated based on the packets successively received by the receiving unit, is increased as compared with a value obtained by multiplying a packet loss rate before the packets that configure the distribution data are received, by a predetermined weight;
• and
• a requesting unit that requests the information distribution apparatus to change a bit rate of the packets that configure the distribution data, based on a judgment result by the first judging unit and a judgment result by the second judging unit.
