摘　　要：在各种网络交换技术中,标签交换技术具有更快的速度,但受其自身因素的限制,标签交换过程中面临各种网络攻击的威胁。将来自不同源但有着相同目的的虚拟电路合并技术引入标签交换中,形成,标签交换路由的合并策略并给出了数学模型和实现方案。在仿真实验中,模拟了由恶意频繁阻塞和流量释放引起的路由与交换间的振荡这种网络攻击,通过对采用合并策略和不采用合并策略的交换机进行比较,证实了合并交换策略具有更高的安全性能。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.
