Embodiment Construction

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0013] see figure 1 , the method of adjusting the priority of the CPU queue based on the ACL, first retains the main process of sending the CPU based on the ACL in the traditional switch chip; secondly, through the ACL key type on the port to find the corresponding type of ACL key, Get the index of the associated data. According to the index of the associated data, the corresponding associated data is obtained. In this associated data, we will set the corresponding flag action to point to the upper CPU. The present invention generally has two situations: one is forwarding to the CPU; the other is indirect forwarding to the CPU.

[0014] The optimization method of the present invention supplements and strengthens the processing process of the upper CPU on the basis of the original t...

Abstract

The invention provides a method for adjusting message uploading CPU queue priority based on ACL. The method comprises a main body process of an uploading CPU based on the ACL in an interchanger chip, and comprises the following steps of: firstly, searching a corresponding type of ACL secret key through the type of an ACL secrete key on an ACL port to obtain an index of associated data; acquiring corresponding associated data according to the index of the associated data; and in the associated data, setting a corresponding mark action to point to the loading CPU. According to the method, different message uploading CPU queues can be realized based on the ACL, and velocity limiting strategies are carried out respectively.

Description

technical field [0001] The invention relates to the technical field of network information processing, in particular to a method for adjusting the priority of a CPU queue for sending messages to a CPU based on an ACL. Background technique [0002] In the traditional switch chip, the access control list ((Access Control List, ACL for short, which is the command list of the router and the switch interface, used to control the data packets entering and leaving the port) can establish various flexible forms for different types of messages. Match the rules and send the message to the CPU for processing, but there is no way to change the priority of the queue that is sent to the CPU. In this way, when doing some speed limit policies for the CPU, there is no way to perform targeted operations. Existing In technology, generally ACL can realize the function of sending different types of packets to the CPU, or send different types of packets to the CPU, but cannot control the priority...
