Traffic control system and method

Abstract

The invention provides a traffic control system and a traffic control method. The system comprises an application information storage module, a scenario configuration module, a traffic control optimization module, a traffic identification module and a traffic control strategy implementation module, wherein the application information storage module is used for storing corresponding relationships among application types, application attribute information and application traffic control modes; the scenario configuration module is used for receiving a scenario configuration parameter input by a user, wherein the scenario configuration parameter carries an application type related to a current scenario; the traffic control optimization module is used for acquiring the scenario configuration parameter and application attribute information and an application traffic control mode corresponding to the application type related to the current scenario, and generating a traffic control strategy for the current scenario according to the acquired scenario configuration parameter, the application attribute information and the application traffic control mode; the traffic identification module is used for identifying the application type of a data packet in a network; and the traffic control strategy implementation module is used for finishing traffic control according to the traffic control strategy for the current scenario and the identified application type of the data packet in the network.

Description

technical field [0001] The invention relates to network security technology, in particular to a flow control system and method, and belongs to the field of network technology. Background technique [0002] With the development of the network, more and more new applications appear in the network environment, and these applications often occupy a large amount of network bandwidth or other resources, making some normal network services unavailable. For example, various types of peer-to-peer (Peer-to-Peer, P2P) downloads, Internet TV streaming media playback, and the like are currently emerging in large numbers. Due to the characteristics of the protocol itself, these applications abuse network resources during use, making services such as HyperText Transfer Protocol (HTTP), File Transfer Protocol (FTP), and mail unavailable. This has seriously affected the use of other normal businesses. How to ensure the bandwidth of key services at network egress, such as HTTP and mail serv...

Problems solved by technology

[0003] The two currently widely used flow control technologies mainly include the following two types: one is the flow control technology based on TCP window shaping, which controls the flow by adjusting the size of the TCP sliding window. The advantage of this technology is that the control scale is more accurate, but Flow control products using this technology have limited performance and generally cannot support traffic exceeding 1G. Once the limit is approached, large errors will occur; the other is queue-based flow control technology, which corresponds to different users, time, and application protocols respectively. , websites, file types and other objects to establish different channels to achieve the corresponding flow control

Although this queue-based flow control technology can control large traffic well, it still has the following defects: because the configuration of flow control parameters for network applications depends entirely on the configuration experience of the administrator, the subjectivity is too strong, and the flow control Low reliability, frequent side effects from misconfiguration
