Merging Strategy and Its Security Analysis for Label Switching Routers

In all of network switching technologies,the label switching technology has a faster speed.But limited by its own factors,label switching faced with a variety of network attacks.Virtual circuits merging was introduced into label switching that it is from different sources but has the same destination.Then merging scheme of label switching and mathematical model was also built.In simulation,network attack was simulated which is oscillation between routing and switching as a result of a malicious frequent suspension and releasing of flows.By comparing common switch and switch on a merging strategy,the method was testified to have a higher level of safety performance.
