Research And Development On BGP Simulator With Automatic Test Function

BGP(Border Gateway Protocal), which is one of the three most famous route protocols, is a different kind of border gateway protocol that communicate among different autonomy systems routers, is a superior distance vector protocol. Dynamics and strong routes are very important to Internet network, so every network engineer who is beginner of this field no only need to understand the conception of route, but also they must have the ability to control it in real condition. Under this precondition, we exigent need a BGP simulate software which face to GER router,to help the user to finish a majority of work as complex configuring and testing.The software should be useable both in IPV4 nerwork and IPV6 network, also it must have roboticized testing function that be controled by Tcl script.This is a challenge topic in BGP testing area.The main work of this topic is as follow:1.Develop BGP4 protocol simulator,under the BGP4 protocol simulator Developped by Prehominid, Continue to develop new function of the implement. Among them,sending 200 Thousand routes in short time,and creativeness add some new functions,such as flap route and reading routes from files.2.Develop BGP4+ protocol simulator,and Aggregate BGP4 simulator and BGP4+ simulator into the same system. BGP4+ is a verson of BGP that base of IPv6,although in present IPv4 is still in main position.But IPv6 will replace IPv4 in the future. Developing BGP4+ protocol simulator make the Implement more Timeliness.3. Creativeness develop Tcl roboticized testing function.For the reason of better Improving the efficiency of testers,we need to come true a test method which is difference whit hand movement testing.The thesis suggest and come true a scheme that Tcl script control the protol simulator to test.From the result of using the software, it well satisfies the need of testing and R&D worker in daily work., effectlly improve the efficiency of work. Compare with the same sofeware in competitive companies, it have excellences as complete function,well stability etc, in the highest flight of internal congener software.
