Information processing apparatus and information processing system

An information processing system comprising:

• a first communication apparatus including a first memory and a first processor coupled to the first memory;
• a second communication apparatus including a second memory and a second processor coupled to the second memory;
• and
• a packet processing device including a third memory and a third processor coupled to the third memory, the third memory includes a plurality of queues each of which stores a part of a plurality of packets and sequentially outputs a stored part of the plurality of packets,
• the first processor is configured to transmit a packet destined to the second communication apparatus via the packet processing device,
• the second processor is configured to receive the packet transmitted from the first communication apparatus via the packet processing device, and
• the third processor is configured to:
• identify a flow composed of a plurality of packets transmitted from the first communication apparatus to the second communication apparatus;
• acquire a feature amount related to the identified flow;
• and
• control a transmission of the plurality of packets to the second communication apparatus based on the acquired feature amount,
• control a transmission rate of the plurality of packets to be equal to or less than a predetermined value,
• suppress congestion of the plurality of packets,
• determine an output queue to which one of the plurality of packets is to be transmitted based on a retention amount of the plurality of packets in addition to the feature amount, and
• transmit the one of the plurality of packets to the output queue.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a process, the process comprising:

• identifying a flow composed of a plurality of packets;
• acquiring a feature amount related to the flow;
• and
• controlling a transmission of the plurality of packets based on the acquired feature amount,
• controlling a transmission rate of the plurality of packets to be equal to or less than a predetermined value,
• suppressing congestion of the plurality of packets,
• determining an output queue to which one of the plurality of packets is to be transmitted based on a retention amount of the plurality of packets in addition to the feature amount, and
• transmitting the one of the plurality of packets to the output queue, and
• the output queue is one of a plurality of queues included in a memory each of which stores a part of the plurality of packets and sequentially outputs a stored part of the plurality of packets.
