| At present,the market competition of operators is extremely fierce,and the dedicated line business of key customer networking has become an important pillar of operators’ revenue,especially in recent years,the proportion of the overall revenue has been rising,which has become an important breakthrough for operators to develop the key customer market and achieve value growth.With the full-service operation and competition,the pure bandwidth-driven development model inevitably leads to the homogenization of dedicated line products and intensifies the competition in the same industry.Perhaps only by enhancing the security and reliability of the bearer network and implementing differentiated development strategies can we have a future.IPRAN is the fastest growing in the evolution of operator intelligence,and it has always been a research hotspot in the field of transport networks.RAN is Radio Access Network,and IP is IP interconnection protocol.Therefore,IPRAN actually refers to "IP-based wireless access network".This thesis studies the networking based on the current mainstream transmission technology,summarizes the current situation of Jiangsu Telecom transmission network from the networks of ZQOTN,SDH and DWDM,and analyzes the demand of IPRAN for carrying customers’ business and the carrying capacity of traditional networking line.It is pointed out that there are some problems in the traditional special line,such as insufficient low-order crossing ability,low flexibility and insufficient protection ability.In view of the constantly changing load bearing requirements of VIP customers,Through the research on the key technologies of IPRAN dedicated line,the IPRAN key customer networking scheme design is put forward,and compared with the traditional networking mode,it is analyzed that the IPRAN based key customer networking dedicated line has the advantages of high bandwidth utilization,flexible networking and scalability.In this thesis,the feasibility of this scheme as a future intelligent bearer scheme is discussed,and a test platform is constructed and the capability test is carried out.Finally,the thesis analyzes the scheme in detail with the actual application of the existing network,verifies the availability of IPRAN networking and achieves the goal of flexible,safe,reliable and low-cost dedicated line for key customers. |
