Embodiment 1

[0045] Embodiment 1 of the present invention provides an ACL matching method to describe the specific implementation process of the embodiment of the present invention in detail, see figure 2 , where the content to be matched is: time: 9:00-11:00, 13:00-17:00; IP address 1.1.1.1-1.1.1.10.

[0046] Step 201: Perform first-level matching on the data packet by using the maximum range matching method.

[0047] In this step, all matching content is converted to generate a range-type numerical value. If there is any matching content that is difficult to convert into a numerical value, it can be placed in subsequent discrete matching for matching. In Embodiment 1, the time can be set to the maximum range: 900-1700; the IP address is 1.1.1.1-1.1.1.10. The above-mentioned range values ​​are stored continuously, so that the data packet matches all the range value contents.

[0048] Step 202: judge the matching result, if all match, go to step 203; and if there is a mismatch, it means...

Abstract

The invention provides an ACL matching method and equipment. The method comprises the steps that first layer matching is conducted on a data package in a maximum range matching mode; when the data package undergoes first layer matching, one time or multiple times of scattering matching is further conducted on the data package, and a matching result is output. After first layer matching is conducted in the maximum range matching mode, scattering matching is further conducted, so that part of matching work is reduced, and certain expansibility is provided for the matching process. In the matching process, the matching mode enables matching to be conducted more easily after the used value range is switched, and matching time is shortened.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an ACL matching method and equipment. Background technique [0002] Access Control List (ACL) is a list of instructions on router and switch interfaces, which is used to control the incoming and outgoing data packets of ports. ACL applies to all routed protocols, such as IP, IPX, AppleTalk, etc., and includes matching relationships, conditions, and query statements, and its purpose is to control certain types of access. ACL is widely used in digital communication products such as routers, switches and firewalls. [0003] In the prior art, the matching content is generally only matched once, and the matching procedure is complex and takes a long time, and the matching content is single and restrictive. Contents of the invention [0004] (1) Technical problems to be solved [0005] The invention provides an ACL matching method and equipment to solve the technical...
