Research On New High Definition Integrated Video Networking Scheme For Guangdong Section Of Wuhan-Guangzhou High-speed Railway

Based on the actual needs of the new high-definition integrated video service and the existing communication resources in Guangdong section of Wuhan-Guangzhou high-speed railway,and the needs of users and economic benefits,this paper proposes a new integrated scheme of high-definition integrated video networking in Guangdong section of Wuhan-Guangzhou high-speed railway.Higher update requirements of the new scheme include network bandwidth requirement,video QOS guarantee requirement,network maintenance management,service protection and network security requirement.The factors that need to be considered in the new scheme include cost,business end requirement,partition planning,system interconnection,etc.Firstly,this paper summarizes the high-speed railway integrated video logical structure,and takes the transmission network networking technology as the research object,compares and analyses the mainstream transmission network technology,focusing on the advantages and disadvantages of each transmission network technology,network structure and existing problems.Secondly,this paper analyses the four requirements of network bandwidth,video QOS guarantee,network maintenance and management,service protection and network security,and comprehensively analyses the cost,service bandwidth requirement,reasonable planning of different regions and system interconnection that should be considered in the construction of transport network.Then,this paper integrates all kinds of technologies,puts forward four networking schemes,and puts forward three key elements,objectives,weights and attributes of scheme selection decision-making,establishes the analysis system of target selection,completes the weights' investigation assignment,attribute analysis assignment and comparison of total attributes,and finally obtains scheme 4 MSTP and OTN combined networking according to the formula of total attribute score calculation of scheme.For the best conclusion,the implementation plan of the scheme is summarized.Finally,this paper briefly describes the implementation effect test of the scheme,and draws a conclusion through the joint debugging test results that the MSTP and OTN joint networking scheme meets the needs of the business side,taking into account the cost,demand,efficiency and security,and is a mature scheme with rationality and generalization.
