Abstract

The invention aims to provide a communication device, a communication system, a communication method, and a communication program which enable appropriate calculation of an available band. A receptionunit 11 receives transmitted packets. A first available band calculation unit 12 and a second available band calculation unit 13 calculate an available band for a transmission source of the packets.A calculation means determination unit 14 determines, on the basis of the reception states of the packets transmitted at predetermined time intervals in the reception unit 11, whether the first available band calculation unit 12 calculates the available band or the second available band calculation unit 13 calculates the available band. The first available band calculation unit 12 calculates the available band on the basis of a reception interval between the packets. The second available band calculation unit 13 calculates the available band on the basis of a time required for the reception ofthe transmitted series of packets and the sizes of the series of the packets.

Description

Technical field [0001] The present invention relates to a communication device, a communication system, a communication method, and a communication program that send and receive packets. Background technique [0002] In order to measure an available frequency band as a frequency band that can be used for communication between one communication device and another communication device, there are cases where each of a plurality of packets is transmitted and received at predetermined time intervals. Note that a series of packets sent at predetermined time intervals is also called a packet column. [0003] In this case, one communication device sends a packet sequence to another communication device. Then, the other communication device calculates the available frequency band based on the transmission interval and the reception interval of a series of packets transmitted by one communication device. [0004] PTL 1 discloses a system for calculating the packet loss rate based on the numb...
