Communication system, communication apparatus, and communication quality test method

A communication apparatus comprising:

• a test data generation unit being configured to generate test data;
• a packet generation unit being configured to generate a test packet having a payload and an error check data in response to a test packet transfer request received from an opposing communication apparatus, the payload containing the test data generated by the test data generation unit, the error check data being used to detecting a digital error occurred in the payload;
• and
• a transmitter unit for sending the test packet to the opposing communication apparatus.

A method for examining communication quality between a first communication apparatus having a test data generation unit configured to generate test data and a second communication apparatus configured to send and receive data with the first communication apparatus, the method comprising:

• the second communication apparatus sending a test packet transfer request to the first communication apparatus;
• the first communication apparatus sending a test packet to the second communication apparatus according to the test packet transfer request, the test packet having a payload including the test data generated by the test data generation unit and the test packet having error check data detectable of a digital error occurred in the payload;
• and
• the second communication apparatus verifying whether a digital error exists in the received test packet according to the error check data.
