Step 101, selects link to be measured, and link head and the tail to be measured are connected to form test closed loop link in turn;
In message repeating network or equipment, select the link to be measured needing test, then the head and the tail of link to be measured are coupled together in turn, the test closed loop link that formation one is airtight thus.The head and the tail of link to be measured connect in turn can craft or automatic ring winding, travels through the link to be measured that will test, makes it end to end, form test closed loop link.
Step 102, injects test packet in test closed loop link;
In above-mentioned airtight test closed loop link, the test packet of transmission network or equipment self-generating is injected in timing, and the type of message can define arbitrarily.
Step 103, the velocity maximum of test closed loop link test transmission message is the throughput of link to be measured; And the velocity maximum of test transmission message is specially, in the continuous several times unit interval, when test packet number, byte number or transmission rate are constant, the actual speed rate that test closed loop link carries.
Optionally, the throughput can carrying out link to be measured carries out ratio setting, namely obtains any percentage throughput required for test by link speed limit mode.
The method of testing of the link performance of the present embodiment, by the path of solderless wrapped connection link to be tested, forms the test closed loop link of closed loop, and or else disconnected injection test packet, is raised speed by message cycle, then realizes the test of high-rate packets equipment performance.
Due to the two ends solderless wrapped connection of two-way service link, link just becomes a closed test loop, the message injected this time can not run off from airtight test loop, therefore by constantly injecting message, data bandwidth in final link reaches the actual saturated bandwidth that can carry of this link, i.e. throughput bandwidth.So do not need external testing tool test, also do not need externally hung software, just can realize remote controlled link performance test that is real-time and low cost.
Above-described embodiment is the process describing the test throughput of link to be measured and the speed of test transmission message, and the packet loss of the time delay and link to be measured that can also treat surveyor's chain road is tested.Fig. 2 is the flow chart of the method for testing of another link performance of the embodiment of the present invention, and as shown in Figure 2, the present embodiment specifically comprises the steps:
