MPLS-VPN At Network Video Frequency Application Within System

On the ages in Internet high speed development, business enterprise inner part of information-based and the information exchanges of the business colleague's is more and more important, VPN network Be solve this need of efficiently one of the ways, drive more and more of customer use. MPLS-VPN because of it in QoS and the discharge engineering of be been one of the important techniques that builds up a VPN network by the industry efficiently.This thesis from pass the theory of the research MPLS-VPN of system to commence, the point introduces the principle of MPLS-VPN, how promote a data report through a label commutation the text delivers in the network of speed; Point out Quality of Service (QoS) is in the modern Internet importance, pass traditional network and the function contrast of QoS that MPLS-VPN can provide, the outstanding MPLS-VPN technique is in the special contribution in QoS. "VChina" is started by Hong Kong, cooperate with Bureau of Education in hinterland everyplace to create of international video frequency education engineering, the purpose is to make Hong Kong and the school of hinterland communicate through an Internet video frequency that carrying on educating is interactive, it old international Internet net because the network obstructs to wait various reason to effectively load, this text passes to make use of a MPLS-VPN technique to carry on an original VPN network reformation and gets stripe and makes use of MPLS-VPN special QoS function and connects into the QoS guarantee project that is different from the business router design use of network loading segment of customer's router of segment to the customer respectively, the customer network after making reformation at face various network environment under can stabilize credibility of provide communication service, display MPLS-VPN technique at to actually when sex request higher business compare traditional Internet special line to have very great advantage.
