Embodiment Construction

[0064] The invention provides a method for providing different quality of service policies for data streams. The core of the invention is: on the premise of not increasing the length of TCAM key, by providing users with some common ACL rule templates, users can realize fine-grained flow classification when configuring ACL without affecting forwarding performance.

[0065] Describe the present invention in detail below in conjunction with accompanying drawing, the specific processing flow of the method of the present invention is as follows Figure 7 shown, including the following steps:

[0066] Step 7-1. Customize some ACL templates according to user requirements.

[0067] In the present invention, firstly, some ACL templates need to be customized according to user's requirements, and the ACL templates may include part of Layer 2 ACL information, part of Layer 3 ACL information and part of Layer 4 ACL information, and may also include some other information. The length of t...

Abstract

The invention provides a method for providing different quality of service (QoS) policies for data flow, mainly comprising: customizing ACL (access control list) template containing partial field information of each layer; using the ACL template to classify data flow and providing different QoS policies for the data flow. And it can implement flexible ACL type selection according to user requirements, implementing more fine grained data flow classification and providing corresponding different QoS policies for the data flow.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for providing different QoS (quality of service) strategies for data streams. Background technique [0002] In the network, it is necessary to classify the data flow, that is, to identify and classify the data flow. Then, according to the result of flow classification, different QoS (Quality of Service) policies are adopted for different data flows. QoS policies are also called "actions", including operations such as discarding, changing priority, and bandwidth limitation. [0003] The traditional flow classification method is to classify the data flow according to the standard quintuple of the data flow message, which is the five fields of the data flow IP message: source IP address, destination IP address, Protocol number, TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) source port number, TCP or UDP destination port number. This method first needs to ex...
