The test parameters at least comprise throughput, packet loss rate, back-to-back value and time delay; wherein the time delay is the difference of the receiving time minus the transmitting time; and
The receiving time and the sending time are acquired by a timer in the network card driving assembly;
The timer is respectively preset in a data message receiving function when receiving the return data message and a data message transmitting function when transmitting the test data message; the method comprises the steps that a timer is respectively added to a data message sending function and a data message receiving function of a virtual network card driving assembly, when a time delay test is carried out, a time stamp T1 when one data message is sent and a time stamp T2 when the one message is received are obtained, the time stamp T1 and the time stamp T2 are recorded in pairs and written into a shared memory, and a network message simulation test program calculates a time delay value by using the value of T2-T1;
If the line speed of the virtual switch to be tested exceeds the line speed of the 10G network card, the virtual switch to be tested is connected with at least a first test virtual network card and a second test virtual network card of two virtual test instruments to obtain test parameters generated by each virtual test instrument;
And taking the average value of the test parameters generated by each virtual test instrument as the final test parameter of the virtual switch to be tested, and forming a test report of the virtual switch to be tested according to the final test parameter.
8. The virtual switch testing system of claim 7, wherein the network message emulation test software further comprises a subscriber management unit;
the user management unit is used for being connected with the control network card so as to provide a web management interface for a user, execute a control command for the user and send the test parameters and the test report to the user.
