A Research Of Network Virtualization Based On LISP Architecture

Network virtualization is a part of diversified Internet architecture,it supports multiple heterogeneous network architecture co-existence in the same underlying physical network,network virtualization provide independently between service providers and infrastructure providers, and making the evolution of the Internet more flexibility.This paper introduces several typical network virtualization technologies in terms of development. First, Virtual Router Redundancy Protocol(VRRP) belongs to virtual routing technologies, and techology like Multi-Protocol Label Switching(MPLS) or Layer2 Virtual Private Network(L2VPN) is popular in present virtual network. Second, OpenFlow technology has attracted much attention, it’s the research focus in current virtual network technology. Finally this paper gives the design of vitual network,and describes the development of this design.This paper mainly covers the following work:Designed a virtual network solution that support the mobile node based on Locator/Identifier Separation the Protocol(LISP), and give communication processes in a variety of network scenarios. Improved the LISP architecture,designed a solution that LISP node be able to use the private identity, and give the communication process of node that use the private identity access virtual network.Finally,this paper discussed the advantages and application prospects of this design.
