Design And Realization Of Automatic Test System For Layer-3Switch

Layer-3switch is primarily designed for telecom operators and network equipmentmanufacturers software testing department. It’s very suitable for LAN routing andswitching equipment for functional and performance testing.In order to speed up data exchange within the large LAN for security and easymanagement considerations must be by function or geographical factors such as largeLAN into a small local area network in order to reduce hazards broadcast storms.Routing and switching equipment in various network plays this role. In the aggregationlevel of small and medium-scale, layer-3switch is increasingly replaced the role of therouter, because of its unique advantages become more and more considered important.Layer-3switch both have route functions, and has layer-2exchange networkspeeds.It can realize the division broadcast area, the isolation broadcast storm; Enhancesthe data packet repeater the efficiency.Has one time the route, retransmits many timesfunction.Realizes data packet high speed repeater and so on regular the by the hardwareprocesses, realizes the route information by the software to renew, the routing listmaintenance, the route computation, the route grades the function firmly.In this thesis, layer-3switch automated test system development and operation ofthe software and hardware environment, studied the layer-3switch automated testsystem uses a key technology, the development environment and operating platforms. Alayer-3switch automated test system architecture and design, overall solution to thethree-layer switch automated test system functions and functions between the variousmodules, and so on. Part of the layer-3switch automated test system design to achieve alayer-3switch automated test system design of layer-3functional automated testmodules. With a network environment for conformance testing, functional testing,performance testing and passive testing capabilities.
