>=With the rapid development of Internet, especially the amount of users and applications growing at a tremendous rate in recent years, network topology is becoming larger and more complicated and traffic is growing exponentially. This makes certain nodes work in a state of high load. If such nodes are attacked, such as virus, it will lead to be overloadable and incapable of working, forcing data packets to reroute, thereby causing other routers to overload successively, and resulting in the cascading failures. Once the large-scale cascading failures take place, they often engender the destructivity and influence powerfully. Therefore, it is necessary to systematically research on the occurred mechanisms and control technologies of cascading failures of Internet. Based on summarizing series of important research works of the complex network's cascading failures, analyzing the characteristics of Internet topology and traffic, in view of the characteristics of heterogeneous distribution of loads and learning from the worm early detection as well as the control technology of forest fire, this paper presents a "two-stage approach" control method for restraining the cascading failures of Internet by closing some nodes or links initiatively. Through the analysis of the propagational characteristics of the cascading failures, this method divides it into two phases: the slow start and the rapid propagation. Through effective control technologies we can detect the cascading failures at the slow-start phase, and then perform the fast response mechanism and take measures timely. The goal of the early detection phase is as early as possible to detect cascading failures occurred. A threshold of "target" is generally defined in traditional methods, such as the number of computers infected by worm virus or nodes and links of their load exceeding the capacity, and then the shortcoming of the methodology is high false alarm rate. Combining the ideas of Kalman filter in the worm early detection area, this paper proposes the detection thinking of "detecting the trend not the threshold" and filters the number of "target" in unit time with the discrete Kalman filter. The aim of effective and fast response mechanism is to slow and prevent cascading failures from the large-scale propagation. Traditional methods only just tolerate a small degree of traffic burst not completely avoid cascading failures, furthermore needing additional investment result in some waste of resources. This paper absorbs the ignition-help method which is widely used to control the forest fire. According to the loads of the various nodes and links in Internet when detecting the occurrence of cascading failures at the slow-start phase, premising not significantly reducing the efficiency of network, the method initiatively closes some of certain "flow generator" nodes or links with high load, mainly because from the perspective of traffic engineering, each node in Internet has two function

随着Internet的飞速发展,尤其是近几年用户数量和应用种类的急剧增加,使得Internet 中的某些节点处在高负荷工作状态。若对这些节点进行攻击,比如病毒攻击,会导致节点过载甚至无法正常工作,迫使数据包重新路由,从而引起其他路由器接连过载,产生相继故障。大规模的相继故障一旦发生,往往具有极强的破坏力和影响力。因此,有必要对Internet相继故障的发生机理和控制技术做深入研究。
