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 aiming at a large-capacity rule table of a packet filtering device, and relates to the test field of the large-capacity rule table of the packet filtering device. In the method, large-scale random network quintuples are generated as a resource pool through script; a packet filtering device API interface is called to randomly select a lot of quintuples from the resource pool to execute rule configuration, an automatic interface of a network tester is called to randomly select a lot of quintuples from the resource pool to execute traffic configuration, and validity condition of the packet filtering device under the large-capacity rule table is verified according to the filtering result; thus, a test scene is fully discretized so as to be similar to an actual scene, meanwhile, rule matching condition of each packet can be obtained accurately, and confidence level of the result is increased.

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...
