%X 利用SDN网络可编程特性和全局网络资源抽象性，提出了一种基于OpenFlow协议的软件定义MPLS流量工程TE和虚拟专用网VPN的实现方法. 该方法使用传统标准MPLS的数据面和基于OpenFlow协议的更加简单且可扩展的控制面，且在原型系统中验证了MPLS TE和VPN功能. 原型验证结果也进一步说明了软件定义网络技术对于简化传统TCP/IP协议体系网络控制面和现有网络设备软件的复杂性均很有效果.<br>Leveraging the device programmability and the abstraction of global infrastructure，this paper propose an openflow protocol based method to implementing the traffic engineering (TE) and virtual private network (VPN)，in which the control protocols (such as LDP，MP-BGP) is greatly simplified and the network data is also forwarded by MPLS labels. In the prototype，the paper verifies the method of proposed software defined MPLS control plane by the functionality of MPLS TE and VPN. The results of prototype verification further illustrates the method effectiveness to simplify the control plane in traditional TCP/IP protocol architecture and reducing the software complexity in implementing the device network control function
