摘　　要：MPLS(Multi-Protocol Label Switch)是一个简化了网络中数据转发的复杂度工业标准,实现了交换技术的转发特性且保留了网络层路由的灵活性与扩展性。MPLS并不是链路层和网络层的合并,而是在网络层和链路层之间定义了一个封装,但是MPLS的实现却是一个问题;IXA是为适应现代高速网络的产物。解决了如何将任务繁重的网络转发功能从通用CPU中解放出来,利用专有的网络处理器来提高转发性能。在IXA上实现MPLS是迎合现代网络发展趋势的一种思路。MPLS is an industrial standard, which simplifies the network forwarding complexity. MPLS does not only realize the characters of forwarding on link-layer, but also retains the flexibilities and extensibilities on network-layer. MPLS is not a combination of link-layer and network-layer. It defmes an encapsulation between link-layer and network-layer. But how to realize MPLS is a problem. IXA has been put forward by Intel for resolving high speed network＇s bottleneck. By making full use of special processors, people can improve network＇s performance can be improved markedly. It is a trend to realize MPLS based on IXA.
