Claim Text:
1. A communication system, comprising: a transmitting device that measures a number of data frames to be transmitted, and then allocates the data frames to be transmitted to a plurality of transmitting links, and then writes a total number of data frames to be transmitted in a data frame loss measurement frame, and then duplicates the written data frame loss measurement frame a same number of times as a number of the plurality of transmitting links to provide duplicated data frame loss measurement frames, and then transmits sets which are made up of the data frames which are allocated and the duplicated data frame loss measurement frames to each of the plurality of transmitting links; a receiving device that receives by a plurality of receiving links which correspond to each of the plurality of transmitting links the sets which are made up of the data frames which are allocated and the duplicated data frame loss measurement frames, and then measures a total number of received data frames, and then writes a total number of received data frames in at least one of the received data frame loss measurement frames; and a measuring device that acquires the at least one data frame loss measurement frame in which the total number of data frames transmitted by the transmitting device and the total number of data frames received by the receiving device have been written, and then measures a data frame loss between the transmitting device and the receiving device by subtracting the total number of data frames received by the receiving device from the total number of data frames transmitted by the transmitting device.
