Research On Resource Allocation And Management Mechanism Of Virtual Routers

Network virtualization technology is considered as an important technology to construct a new generation of Internet.The essence is to make the service provider to create a number of virtual networks on the same underlying physical network,so as to provide users with a variety of customized end-to-end services.Virtual router technology is an important research direction of network virtualization technology.The purpose is to divide the physical network resources into a number of virtual routers.Each virtual router has a customized routing protocol,packet forwarding capability and interface communication capability.The problem of resource allocation and management is the key technology of virtual router system.The main purpose is to map the virtual network resource request to the physical resources effectively,and improve the utilization rate of the physical network resource,as far as possible to meet the requirements of virtual network service.The mapping strategy and management method of virtual router resource requests to physical network resources determine the utilization rate of physical resources and virtual network system performance,which has important application value in the research of this problem.This thesis is based on the physical resources such as the control node,forwarding board and interface board and the virtual router instance creation and management requirements for virtual resource allocation algorithm.The virtual resource allocation and management system is studied.The paper designs a resource allocation and management system.Distribution and management of the original system,the system has the control node,forwarding board and interface board and other physical resources for registration,online testing and the creation and the delete of virtual routers,and other management functions.The research project of "virtual network resource allocation and management technology" research project has important reference value,which lays a good foundation for the design and implementation of resource mapping and management system.
