The Decision Risk Analysis Of Typical Local Area Network By Fault Tree Analysis

The computer networks are being more and more large. But security of network is a latent problem. The Ethernet is one of most important member in computer networks. The computer networks including Ethernet are faced with tremendous security threaten now. The ingredients of security threaten are manifold. The net workers (Inc network erector and network maintenance man) always depend on their personal experience and phenomena they saw to judge the problem. Unfortunately, the judgment is not well and truly for sponging on personal capability of net workers.We refer FTA (Fault Tree Analysis) to analysis typical Ethernet LAN as Network Manager. FTA is an effective method for system reliability analysis. Mr. White of Bell Telephone Laboratories developed the concept in 1962 for U.S. Air Force using with the Minuteman system. This article will make use of FTA method to analysis the typical Ethernet. FTA is a good theory which will help us to be conscious of the network threaten and avoid the harm of network threaten in Ethernet.
