Abstract
A communication system is provided which includes a first communication device for transmitting a plurality of packets in different packet sizes, and a second communication device having a reception unit for receiving over one or more links packets transmitted from the first communication device, and a calculation unit for calculating a packet loss rate for each packet size based on reception result of the reception unit. The communication system estimates a bit error rate during link transmission of the packets from a difference of the packet sizes of the packets transmitted from the first communication device as well as from the packet loss rate for each packet size calculated by the calculation unit.
