Network Fault Location System Research And Design Of The Enterprise

This article selected topic origin of Hubei province natural science fund project(no.2009 chb008)-congestion control of stream control transmission protocol new calculation model for research.The objects include networking equipment of the physical layer and data link layer,such as security equipment,storage devices,servers and other hardware equipment.The traditional network management is monitoring fault phenomena of the managed object,or receiving failure report of the management object,and creating and maintain fault logging libraries.Then the implement network fault location is by artificial analysis of the fault log.However,the current business complex network in large networks.Because of all kinds of business application is varied,so a lot of uncertainty is led to the network failure.At the same time,this uncertainty makes artificial positioning network failure brought more severe challenges.Ant colony algorithm that Similar to the TSP、VRP model is one of the many uncertainties technology.It involves the Internet search problem that have a good positive feedback and fault tolerance.Meanwhile,it has a good balance in two aspects of complexity and accuracy,and suitable for large-scale network environment.So the paper takes precision,convergence and efficiency of locate fault of ant colony algorithm as the goal.To achieve the in-depth research and analysis of fault location technology in the large enterprise network.At first,this paper further summarizes the commonly used network fault location technology,then analyzes the advantages and disadvantages of certainty and uncertainty.This paper proposes a network fault location method based on ant colony algorithm.In order to adapt to changes in the large-scale enterprise network environment,we introduce network analyzer and probe;For the convenience of analyzer and probe the communication between the network,we improve the communication protocol between them;In order to adapt to the fault dynamics,we introduce time information;In order to solve the problem of network fault upstream and downstream,we introduce pheromone concentration.This paper verified the accuracy of this algorithm by experimental simulation on the more network nodes,the less deployment of the network probe and the smallest search failure time.Finally,we based on the large companies(Hubei radio and television fire phoenix TV advertising medium resource library(BeiBo)system)in the network environment,for example.Through the enterprise network security needs to carry on the comprehensive analysis and design.Setting up within the enterprise network on the GNS3 simulation platform.We realized the communication of enterprise network interconnection with basic network technology such as VLAN,HSRP,STP,TRUNK,Link Aggregation,Firewall,Redundancy,and VPN,etc.On this basis,we implemented the enterprise network fault location system based on ant colony algorithm by programming.Positioning network fault based on ant colony algorithm is proved to be superior to other common algorithms through the analysis of the test system and fault case analysis in a large enterprise.
