Design And Implementation Of IP Bearer Network System

IP bearer network is an exclusive network by using IP technology; BearerNetwork is usually used on the business which require higher transmissionquality.(For instances, soft switch, video, VIP VPN, etc.). Because Bearer network isdifferent from current IP Internet; therefore, we defined the network which carryingnext generation telecommunication service (ex, next generation network (NGN),3G,)as Bearer network.To adapt its network higher QoS, security, reliability, and failure to quicklyrestore the capacity requirements and the IP bearer network came into being. IP bearernetwork is a private network built by the various operators based on IP technology,used to carry the business of high transmission quality requirements, such assoftswitch, video, focusing on customer VPN different from the existing IP Internet,will host the next generation network (NGN),3G telecommunications business IPnetwork is defined as the IP bearer network. In simple terms, the IP bearer network=IP network technology+carrier-class operational needs.The paper first examines thebackground of the IP bearer network technology, the technical principles of the statusquo at home and abroad and the IP bearer network; focuses on MPLS technologies,MPLS/VPN formation of networks the way, the IP bearer network QoSimplementations. IP bearer network to achieve design based on the status quo ofdomestic and international IP bearer network analysis.1、The network hierarchy, routing scheme, node access solutions, networktopology program.2、Combination of demand, given the IP address planning, design and IP bearernetwork QoS solution implemented.3、IP bearer network applications and tested to verify the feasibility of thenetwork.With communication technology and the demand for services continues torepresentatives of the IP bearer network technology can solve the problems faced byIP bearer network architecture, reliability, QoS, security, and network management,the development of the societyvaluable.
