Problems solved by technology
This shows that the proportion of system resources used by firewall B to tear down and create new TCP connections at this stage is much larger than that of firewall A, which also greatly affects the test comparison results of the two concurrency performance
[0014] (2) It is difficult to guarantee that the preset Ts value is applicable to all devices under test
When there are many devices under test and the tests are not performed at the same time, according to the requirements of formula 2-2, the maximum TCP new rate Vm of some devices under test may be less than Vs, resulting in the need to re-determine the value of Ts. Circumstances affecting already completed test items
[0015] From the above analysis, it can be seen that the setting of the ramp time Ts value is an important part of the entire TCP concurrent connection test, and the test method of fixing the Ts value is difficult to solve the above two problems

Embodiment Construction
[0025] The attached picture is a schematic diagram of an example of the TCP maximum concurrent test configuration of the Spirent Avalanche tester.
[0026] The embodiment of the method for testing the number of TCP concurrent connections based on the maximum new rate of the present invention is a method of demolishing and building while including the climbing stage. Among them, based on the maximum TCP establishment rate of the device under test, different Ts values are taken for different devices under test, so that the TCP establishment rate Vs in the climbing phase is a fixed ratio N of the maximum TCP establishment rate Vm of the equipment; combined with formula 2 -1, Ts value can be obtained by formula 2-3;
[0027] Ts=Cm / (Vm*N) Formula 2-3;
[0028] Among them, N can be determined by the test unit itself, and it will not affect the fairness of the test.

A firewall TCP concurrent connection testing method based on the maximum new connection rate is a method of clearing while building in the climbing stage. The method is characterized in that in a climbing stage test, on the basis of the TCP maximum new connection rate of devices to be tested and according to different devices to be tested, different Ts values are obtained, so that a TCP new connection rate Vs of the climbing stage is the fixed ratio N of the TCP maximum new connection rate Vm of the devices; with the combination of a formula 2-1, the Ts values can be obtained through a formula 2-3 that Ts=Cm / (Vm*N), and N can be determined by a testing unit. According to the firewall TCP concurrent connection testing method, influence of TCP new connection performance of the devices on the TCP maximum concurrent connection performance test result is little, in the maintain stage of the testing process, and the devices to be tested can reflect concurrent performance more objectively on the condition that the devices to be tested work on the same resource load proportion condition; the fact that all the devices to be tested operate on the same testing condition standard is guaranteed.
Description
technical field [0001] The invention relates to a method for testing the number of concurrent TCP connections of a firewall, in particular to a method for testing the number of concurrent TCP connections of a firewall based on the maximum new rate. Background technique [0002] The main goal of the maximum concurrent test is to evaluate the ability of the device under test to manage and maintain TCP connections. Generally speaking, the larger the memory of the device, the more session table space, and the stronger the ability to manage sessions, the higher the TCP concurrency capability of the device. [0003] Generally speaking, there are two test methods for the number of concurrent TCP connections, one is the "build but not tear down" method, and the other is the "build while tearing down" method. The test method of "only building but not tearing down" means that after the TCP connection is established and the specified page is obtained, the connection is kept until the ...
