Study Of Traffic Control Based On Linux's Model And Application On The Campus Network

As the fast development and the prevalence of the computer networks technique is going on, there is a great progress in the development of the campus and area network. In recent years, some of the universities, hospitals, corporations etc have established their own local area network(LAN). Especially, the campus network is just the case of them, for its new types of multifarious business, video education, Video-On-Demand, far-distance education, the use of multimedia, and so on. The networking transmission is experiencing a great change, which is from simplex data to multimedia including voice, image and so forth. It gradually becomes a pop trend. Then the problems are put forword, that the network congestion happens easily for the limited bandwidth. And it turns into the bottle-neck of the network development. How should we like to solve it? It is a right way for us to study on the quality of service (QoS) on network and the management and control of the bandwidth. In another hand, in the use of network colleges are a special colony because usually it must protect some departments from the network congestion or interruption by special channel of the bandwidth. It is also an important reason why the traffic control(TC) should be increased.Recently the kernel of Linux is being more and more perfect and its network function turns to be stronger. For an instance, the TC packet expert in traffic control is just the new added item in the kernel of Linux. The numerous and powerful qdisc arithmetics and classifiers offer us to set the bandwidth in our pleasure. Aiming at the characteristics of the campus and area network such as campus network, in this article a set of feasible methods about the bandwidth distribution and traffic control is carried out based on the studies about the traffic control. The design is accomplished with the use of the TC model of the Linux system. Firstly, it is mainly about the parse and study on the kernel of traffic control and the queue arithmetic. But what is more worthy is the design strategy and the implemented methods brought forword in the following. Also, the prevention and cure of the virus about the traffic control is discussed.
