Patent ID: 7436776

Claim:
A communication test device for conducting a communication test on a repeater connected to networks, comprising: data frame generating means for randomly generating first data frames conformable to a first communication protocol and second data frames conformable to a second communication protocol; sequential number attaching means for attaching sequential numbers to the first and second data frames consecutively; test data attaching means for attaching test data to the first and second data frames; transmitting means for transmitting the first and second data frames to the repeater in order of the attached numbers; receiving means for receiving the first and second data frames from the repeater; sequential number judging means for determining whether or not the first and second data frames have been received in order of the numbers; and test data comparing means for comparing the test data attached to the received first and second data frames with the test data attached by said test data attaching means, wherein said data frame generating means controls a ratio of generation of the first data frames to the second data frames in accordance with an externally input instruction.
