specific Embodiment approach

[0055] For the convenience of description, assume the following network environment: Hosts A and B access the Internet through a LAN switch and an exit router. The server of the flow control system is set up between the LAN switch and the exit router. The server has two network cards responsible for uploading and Download traffic control, the network card eth1 is responsible for managing the download traffic of the internal network, and the network card eth0 is responsible for managing the upload traffic of the internal network. Run the Web browser, FTP, and eMule client programs on the intranet client of user group A to access the Internet. The specific implementation is as follows:

[0056] 1. Host A opens the Web browser, FTP and eMule clients respectively, and initiates a login request to the Internet server.

[0057] 2. The three types of traffic data packets sent by host A pass through the switch and reach the flow control system. The system uses regular expressions to ...

Abstract

The invention relates to a flow control method based on application layer detection .The flow control method based on the application layer detection is a systematic method of identification and control for the flow of a variety of web services. Bandwidth management is carried out for different user groups. Different bandwidths are distributed to different user groups according to difference of businesses of departments in enterprises. The bandwidths of some users are limited. Each group of users can obtain the minimum guaranteed bandwidth whenever the users surf the internet and network congestion can be avoided. Maximum bandwidth which can be borrowed and borrowing priority of each group are set at the same time. Therefore, waste of resources caused by excess bandwidths of sub-networks can be avoided and users of high priority can borrow more remaining bandwidths. Bandwidth management is carried out for different application protocols. Different bandwidths are distributed to different application protocols according to criticality of businesses. Different priority levels are set, and non-critical business flow of peer-to-peer (P2P) and the like are restrained. Therefore, service quality of critical businesses is guaranteed.

Description

technical field [0001] The invention is a flow identification and control system method for various network services. It is mainly used to solve the network congestion caused by various applications competing for network bandwidth resources, ensure users' basic guaranteed bandwidth, suppress non-critical business traffic, and improve network service quality. It belongs to the field of traffic identification and control. Background technique [0002] In recent years, with the rapid development of computer network technology and multimedia technology, various comprehensive services have become more and more widely used. The traditional packet switching network is designed for non-real-time data communication such as FTP and E-mail, but now various distributed multimedia applications include not only text data, but also multimedia information such as images, voice and video. Some key applications have high requirements on network bandwidth, delay, and jitter, but some non-key ...
