The virtualization of the Router’s Main Control unit function based on the x86 platform can provide support for several technologies including virtualization

Software Defined Network（SDN）and cloud computing for further applications.Traditional router code is developed on private network processor.In order to achieve traditional function of a router in a virtualized environment

we recompile the virtual network interface card’s board support package

drive and protocol stacks based on traditional router code.This method realizes the router’s code mirror running normally in Vmware virtual machines based on normal Windows platform.The feasibility is also verified by the sending and receiving packet test.Compared with the traditional method of programmable router virtualization

this method utilizes a pure software virtualization technology and it is based on VxWorks router protocol stack

which shows much better versatility and flexibility.
