Method and system for obtaining maximum concurrent connection number of firewall

Abstract

The invention discloses a method and system for obtaining the maximum concurrent connection number of a firewall, capable of accurately testing the maximum concurrent connection number of the firewall, simplifying a step of testing the maximum concurrent connection number of the firewall, increasing the performance testing efficiency of the firewall and reducing the cost. The method comprises the following steps: S1, obtaining the current total connection number n1 of the firewall and the size c1 of a used memory; S2, obtaining the total connection number n2 of the firewall and the size c2 of the used memory after a pre-set time; S3, judging whether n1=n2 is workable or not, if so, returning to the step S1, and or else, performing a step S4; and S4, calculating the maximum concurrent connection number N of the firewall, wherein the calculation formula is N=n2+(c-c2)*(n2-n1) / (c2-c1); and c is the memory capacity of the firewall.

Description

technical field [0001] The invention relates to the technical field of firewall performance, in particular to a method and system for obtaining the maximum number of concurrent connections of a firewall. Background technique [0002] The number of concurrent connections in the firewall connection table refers to the maximum number of connections that the firewall device can establish, and the number of concurrent connections is one of the important parameters to measure the performance of the firewall device. The higher the number of concurrency, the higher the performance of the firewall device. Therefore, people often need to obtain the firewall concurrent number when evaluating the performance level of the firewall. However, the process of obtaining the firewall concurrent number is very complicated, and it is necessary to use a high-performance tester to test the acquisition. This kind of tester is expensive, and generally small companies cannot buy it. From the beginni...

Therefore, people often need to obtain the firewall concurrent number when evaluating the performance level of the firewall. However, the process of obtaining the firewall concurrent number is very complicated, and it is necessary to use a high-performance tester to test the acquisition. This kind of tester is expensive, and generally small companies cannot buy it. From the beginning, even if a large company buys the device, due to the limited number of physical boards of the tester, testers from multiple departments need to queue up to use it. At the same time, it is necessary to build a test network environment and configure the tester (the configuration process is more complicated), which makes it difficult to use existing The test steps of some testers to test the maximum number of concurrent connections of the firewall are too cumbersome, which seriously affects the efficiency of firewall performance testing
