Design And Implementation Of Multi-service Bearer Network For Regional Enterprises

With the continuous integration and progress of Internet technology and information service and the increase of the number of network nodes,the data networks are increasingly complicated since the regional enterprise networks are needed to serve major production operations.Meanwhile,the current communication networks also have higher technical requirements,no longer as the previous transmission of a single data,but to transmit multiple data such as production information,voice,data,and video to provide high-speed,safe and multi-service concurrent network platforms to meet the diverse needs of network users.Therefore,only when regional enterprises combine their own needs,build multi-service bearer networks,improve the security and flexibility of networks,meet the needs of emerging businesses and promote the quality of network services,can they seize the initiative in the increasingly competitive communication service market and achieve the comprehensive and sustainable development of the enterprises.For the purpose of solving the problem of aging optical transmission equipment,unreasonable network structure and low network stability of a professional communication operator affiliated to the oilfield,the study carried out the design and function realization test of multi-service bearer network for regional enterprises.In this thesis,the problems existing in the current network of the enterprise were firstly analyzed on the basis of the current operating status of the network structure and the services that the enterprises had contracted,and then the construction of a multi-service bearer network based on RRPP and MPLS VPN technologies was proposed.In this thesis,we designed the overall networking scheme from transmission ring,MPLS VPN and network flattening such three aspects,and planned the basic environment of network,route and MPLS VPN according to the requirements of oilfield management and the services that the enterprises had contracted,and discussed the realization and test of RRPP ring and MPLS VPN by taking the key configuration and service test of typical communication station equipment as examples.At present,the multi-service bearer network established by the enterprise has been successfully put into use and provided users with services of high reliability,high flexibility and high quality.The result of use is good.In this thesis,by combining with the work in the construction of enterprise multi-service bearer network,the author summarizes the multi-service bearer network based on RRPP/MPLS VPN and expresses the expectation of the future.The work in this thesis provides reference and guidance for other regional enterprises to construct the multi-service bearer work.
