Research On Network Reconstruction Of Telecom Operators' Business Cloud Platform Based On SDN

As the "Internet +,made in China 2025,smart city" concept is put forward,such as intelligent terminals and cloud services a large number of popularization and application,prompted a rapid surge in network size and flow,it also makes the traditional data communication network faces many new challenges.At the same time,with SDN(Software Define Network)technology as the core of the emerging network technology constantly emerging,effectively promote the network infrastructure and information service to start a new round of change.At present,the cloud platform is already the mainstream construction mode for telecom operators,then the traditional network architecture of the telecom operators' business cloud platform has such problems as complex network and lack of flexibility,which has slowed down the progress of the business launch,so reconstructing the network architecture of business cloud platform is an important measure to ensure the rapid and normal development of new business for telecom operators.As a new technology that subverts the traditional network architecture,SDN is an important direction for future network evolution and has become a hot spot in the current industry.Through SDN,the automation and intelligence level of the network architecture of the telecom operators' business cloud platform can be effectively improved.It is also an important breakthrough direction for telecom operators to "Go to telecommunications",and finally achieve the goal of "cloud computing and network convergence".This paper adopts the research method of combining theory with practice,and the main contents and results are as follows:(1)Research on the core technology of SDN.On this basis,it's combined with the characteristics of telecom operators,proposed a technical solution for introduction of SDN into telecom operators' business cloud platform: VxLAN+NFV.(2)Analyze the pain points of the network architecture of telecom operators' business cloud platform,and the need to introduce SDN.On this basis,the network reconstruction of telecom operators' business cloud platform is planned in detail.The planning content includes the overall technical architecture,SDN and cloud computing management platform docking solution,network virtualization planning,intelligent flow scheduling and so on.(3)The laboratory simulation test of SDN products and solutions of different SDN manufacturers was carried out in 42 scenarios,and the test results are analyzed in depth.(4)Based on the planning scheme and the laboratory simulation test,combined with the current situation of telecom operators' business cloud platform network,the network reconfiguration deployment scheme based on SDN is designed,and put forward two-step evolution scheme.By the end of the article to summarize full text work,and for future work is prospected.
