Problems solved by technology

The test scenario of this method is not realistic enough to find possible problems in the real environment, because discrete traffic and regular traffic exert different pressures on the packet filtering device matching algorithm

Embodiment Construction

[0027] Below in conjunction with accompanying drawing, content of the present invention is set forth in more detail:

[0028] first as figure 1 Deployment network environment shown: Connect the network test instrument to the service port of the packet filtering device in series (the receiving end of the instrument is connected to the transmitting end of the device under test, and the transmitting end of the instrument is connected to the receiving end of the Test instrument client), the management port of the packet filtering device and the network test instrument management port are connected in the same network segment.

[0029] Then if figure 2 As shown, execute the random network quintuple generation script, the total number of quintuples input by the user num_list=1000000, the source IP start address sip_start=1.1.1.1, the destination IP start address dip_start=2.1.1.1, the packet filtering device The number of rules to be configured in num=600000, and then enter the i...

Abstract

The invention provides an automatic testing method for a large-capacity rule table of a packet filtering device, and relates to the field of testing the large-capacity rule table of a packet filtering device. The invention generates a large-scale random network quintuple as a resource pool through a script; and the packet filtering device is called. The API interface randomly selects a large number of quintuple from the resource pool for rule configuration, calls the automated interface of the network tester to randomly select a large number of quintuple from the resource pool for traffic configuration, and verifies that the packet filtering device is in the large-capacity rule table according to the filtering result. Therefore, the test scene is sufficiently discrete to be close to the actual scene, and at the same time, the rule matching situation of each package can be accurately obtained, which increases the credibility of the result.

Description

technical field [0001] The invention relates to a testing method for a large-capacity rule table of a packet filtering device, in particular to an automatic testing method for a large-capacity rule table of a packet filtering device. Background technique [0002] The general test method for the large-capacity rule table of the packet filter device is: create a continuous IP segment, fixed port and protocol simulation traffic on the network tester, configure the corresponding rule table on the packet filter device, and then send traffic to view the packet filter Condition. The test scenarios of this method are not realistic enough to detect possible problems in the real environment, because discrete traffic and regular traffic exert different pressures on the matching algorithm of the packet filtering device. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an automatic testing method for a large-capacity rule table of...
