Research On The Interaction Of A Smart City Network Construction Across Multiple Bearing Planes

With the development of communication technology,especially the transmission technology of basic pipeline,the solution of government-enterprise customer service that can be supported by operators' basic network is changing constantly.From the point of view of the actual demand of government-enterprise customer information networking,it will certainly develop with it,but the trend of existing stock technology and incremental business demand is also changing.In terms of business,the demand of customers has gradually surpassed the physical network performance of actual operators.For China Unicom,the deployment of new networks must take full account of investment and maintenance costs.During this period,the gradual evolution of speech work at the infrastructure level is particularly important.At the same time,most of the basic transport plane networks in the existing network stock of operators are composed of a variety of equipment manufacturer systems.In some business cases,some interoperability work has been achieved.In response to the increasingly complex needs of government and enterprise business networking,but as far as the overall speech trend is concerned,the decoupling problem of multi-vendor equipment has become a painful point in the future.This topic originates from the construction of the test environment of a smart city project which is planned to be built by a district government and a company recently.Starting from the contradiction between the demand of the project and the actual network carrying capacity,and based on the company's basic network capacity,on the basis of the existing technology,especially on the basis of the stock access layer technology.Taking practical engineering samples such as difficult testing and project implementation involved in deploying test environment in actual work as an example,the comprehensive solution design and verification work across multiple bearing plane problems are completed by simulating and constructing customer demand scenarios.At the same time,the basic network test environment built in this paper is similar to 5G maturity.After the deployment of network effect,this study explores the impact of complex networking environment on the whole government-enterprise customer networking technology on the basis of setting up the test work.Meanwhile,it combs the related response process within the company through the relevant test work,and makes a good technical reserve for the low-cost construction of some application scenarios.The main body discusses the following aspects:(1)Analysis of the actual situation of the project,starting from the business needs of the project.Based on the requirement of networking test in a smart city recently involved,this paper analyses the problems of data interaction in the process of project implementation from the point of view of resource requirement of transmission pipeline side in actual project demand,and puts forward some problems.Based on the analysis of the common business solutions and related technical characteristics provided by the author in an operator in Kunming,the contradiction between the existing basic network and the new business needs is analyzed,and the necessity of interactive research is emphasized.(2)Demonstrate the necessity of the study of the whole interaction problem,initially put forward the solution of the whole interaction problem,and then analyze and demonstrate the work according to the design plan.(3)The solution of practical interactive problems and the research of technical characteristics are analyzed in detail according to the bearing plane dimension,and the existing stock bearing plane technology,equipment characteristics,combination selection and other aspects are comprehensively demonstrated to complete the carding work according to the common characteristics of existing plane application schemes.The interaction problems of SDH transmission layer,IPRan transmission layer,Internet line layer,VPDN wireless side layer and cloud layer are discussed respectively,and the design of test environment is simulated and built.(4)Designing interworking schemes across multiple bearing planes,verifying and testing them by modules.(5)Found that the testing work and problems in the research process.This research also completes the construction of complex networking requirements testing environment for actual government-enterprise projects.This paper extracts and analyses the new complex project requirement difficulties,then complete the design work of different requirement points,and finally complete the related test work according to different plane characteristics.It solves the problem that the complex networking requirement of the company does not match the carrying capacity of the basic network,and completes the new scheme of using the stock basic network to realize the complex networking before the deployment of the new technology network is completed.At present,the scheme is applied normally and has good response.
