Campus Network Fault Analysis And Positioning Technology Research

Network management is to ensure a reliable and efficient operation of the network fault management is an important process, the main function of network management, network fault fault location is the core content of management. The traditional network expert in manual mode on the fault location already cannot satisfy the needs of contemporary network, intelligent fault location technology called, in order to realize the automation network fault location. Intelligent network fault location technology research, development and adaptive information security system, establish effective fault orientation concept and promote network fault diagnosis precision, has become the urgent needs of informatization construction. From the characteristics of campus development present situation, and to improve the accuracy of the network fault location and time of campus network, the fault analysis and positioning technology were studied.On the basis of previous work, the main research work and innovation are as follows:(1) analysis of the current problems existing in the campus network, and summarizes the characteristics, structure and development prospect are discussed, and the simple network management protocol to the basic principle of network application in the feasibility and superiority of fault location.(2) based on the existing research results of existing network fault location technology is studied and analyzed carefully studied their advantages and disadvantages, core algorithm was proposed based on asynchronous alarm and graph method combining for fault location.(3) is presented in the campus network fault location into similar patterns of thought, TSP in front of the theoretical analysis and the topological structure of the campus network into a special kind of abstraction, using the network optimization to solve this problem. Abstract a network model of the fault location with the fault location for campus network, and laid a theoretical foundation.(4) according to the theory of ideological front, a method based on ant colony algorithm of network fault location technology, based on ant colony algorithm of positive feedback and fault-tolerance characteristics of local and global optimization, and further puts forward the thoughts and grading of the algorithm is improved, the campus network as the branch and into several independent area, stratified solution to the whole region and a global optimization. To improve the fault location of global optimization ability and network fault location accuracy.For the fault location algorithm of campus network, and its validity and performance need validation. Finally the programming of ant colony algorithm based on the campus network fault location algorithm, and the algorithm was tested. The ant colony algorithm is proved superior to the average fault location algorithm thoughts in positioning accuracy, have a certain improvement.
