Abstract
A communication system includes a transmitter configured to transmit a packet, a repeater configured to impose a bandwidth limit on the packet, a receiver configured to receive the packet on which the bandwidth limit is imposed, and a control device configured to set, when a reception interval of reception packets received by the receiver is longer than a transmission interval of packets transmitted to the repeater, a transmission rate in the transmitter in accordance with the reception interval.
Claims17
A communication system, comprising:
- a transmitter including a first hardware processor configured to:
- transmit a plurality of packets at specified transmission intervals;
- a relay device including a second hardware processor configured to:
- receive the plurality of packets from the transmitter;
- and
- forward the plurality of packets;
- a receiver including a third hardware processor configured to:
- receive the plurality of packets from the relay device;
- and
- a control device including a fourth hardware processor configured to:
- detect a second period in which a second plurality of packets from among the plurality of transmitted packets are received by the receiver at second reception intervals that are longer than the specified transmission intervals, the second period following after a first period in which a first plurality of packets from among the plurality of transmitted packets are received by the receiver at first reception intervals that are the same as the specified transmission intervals;
- and
- adjust a transmission rate in the transmitter based on a difference between a length of the second reception intervals and a length of the first reception intervals.

A communication controller connectable to a transmitter, the transmitter including a first hardware processor configured to transmit a plurality of packets at specified transmission intervals, the communication controller comprising:
- a memory;
- and
- a second hardware processor coupled to the memory and configured to execute a process, the process including:
- setting a transmission rate in the transmitter in accordance with a reception interval of reception packets received by a receiver, when the reception interval is longer than a transmission interval of packets transmitted to a relay device which imposes a bandwidth limit on a packet which is transmitted by the transmitter by:
- detecting a first period in which a second plurality of packets from among the plurality of transmitted packets are received by the receiver at first reception intervals that are longer than specified transmission intervals at which the transmitter transmits packets, the first period following after a second period in which a first plurality of packets from among the plurality of transmitted packets are received by the receiver at second reception intervals that are the same as the specified transmission intervals, and
- adjusting the transmission rate in the transmitter based on a difference between a length of the second reception intervals and a length of the first reception intervals.

A communication control method executed by a computer, comprising:
- setting a transmission rate in a transmitter in accordance with a reception interval of reception packets received by a receiver, when the reception interval is longer than a transmission interval of a plurality of packets transmitted to a relay device which imposes a bandwidth limit on a packet which is transmitted by the transmitter by:
- detecting a first period in which a second plurality of packets from among the plurality of transmitted packets are received by the receiver at first reception intervals that are longer than specified transmission intervals at which the transmitter transmits packets, the first period following after a second period in which a first plurality of packets from among the plurality of transmitted packets are received by the receiver at second reception intervals that are the same as the specified transmission intervals, and
- adjusting the transmission rate in the transmitter based on a difference between a length of the second reception intervals and a length of the first reception intervals.
A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a digital signature process, the digital signature process comprising:
- setting a transmission rate in a transmitter in accordance with a reception interval of reception packets received by a receiver, when the reception interval is longer than the transmission interval of a plurality of packets transmitted to a relay device which imposes a bandwidth limit on a packet which is transmitted by the transmitter by:
- detecting a first period in which a second plurality of packets from among the plurality of transmitted packets are received by the receiver at first reception intervals that are longer than specified transmission intervals at which the transmitter transmits packets, the first period following after a second period in which a first plurality of packets from among the plurality of transmitted packets are received by the receiver at second reception intervals that are the same as the specified transmission intervals, and
- adjusting the transmission rate in the transmitter based on a difference between a length of the second reception intervals and a length of the first reception intervals.
A communication control method executed by a computer, the method comprising:
- comparing a transmission interval and a reception interval of a relay device;
- and
- setting a transmission rate in a transmitter based on a reception interval of a receiver having a bandwidth limit responsive to the comparing by:
- detecting a first period in which a second plurality of packets from among a plurality of packets are received by the receiver at first reception intervals that are longer than specified transmission intervals at which the transmitter transmits packets, the first period following after a second period in which a first plurality of packets from among the plurality of packets are received by the receiver at second reception intervals that are the same as the specified transmission intervals, and
- adjusting the transmission rate in the transmitter based on a difference between a length of the second reception intervals and a length of the first reception intervals.
