Network performance test method

The invention provides a network performance testing method, and its kernel: setting IPv6 test extension head in IPv6 data message to carry test information and testing network performance for IPv6 data message transmission in network according the extension head. And it can complete network performance test on the condition of setting no added test monitoring equipment and needing not to construct special test messages, extremely convenient to network performance test. And it can meet various network test requirements, thus simplifying the testing method and reducing the testing cost.
