Based On The Mpls-vpn Network Research And Applications

Traditional IP data is transmitted on a case-by-jumping-1ike, Each transponder data IP router Baotou in accordance with the purpose of identifying addresses routing table to be under the dive of exports, This is a cumbersome and inefficient, The main reason is twofold : 1, routing some of the inquiries have conducted a number of routing table search. This is the so-called recursive search 2, follow Route matching the longest match, Therefore, forcing almost all the routers exchange engine must use software to achieve, use the software to exchange engines and ATM switches with hardware to achieve the efficient exchange of engines unable to match。Today's Internet applications increasing demand for bandwidth, delay of the increasingly high demands。How to improve the efficiency of transmitting various router manufacturers have done a lot of improvements, If Cisco router to provide the CEF (Cisco Express Forwarding) function revised routing table search algorithm, and so on. But these patch will not solve the current problems faced by。This paper from the process of transmitting data, VPN MPLS VPN Routing Protocol in respect of the principles of on the Lam, routing and routing address goals important to distinguish the concept of VPN topology routing goal in the control of the important role that summarizes the technical features of MPLS VPN. MPLS VPN based on the research work on the basis of principle and, BGP achieve given based on the expansion of a network of MPLS VPN model This model also describes the functions of the various equipment, MPLS VPN analysis of the technological advantages and application prospects. MPLS VPN technology and in accordance with the principle embodied in the practical application advantages project demand of the unit, from a practical example of an in-depth analysis of MPLS VPN. In this paper, based on MPLS VPN-building programs.
