| Full-service operation refers to a cross-industry and cross-regional operation mode covering multiple business fields such as telecommunications,Internet,multimedia,entertainment,consumer electronics,finance and health,which comprehensively meets users' living and working needs and provides communication,content,application and services.Among them,data service is an important part of the whole business operation,so the growth of data service has new requirements for the existing transmission network.It is necessary to improve the network structure of transmission network and improve the efficiency of transmission network.Firstly,this thesis introduces the characteristics and main technologies of the transmission network in the context of the whole business operation.Due to the pressure brought by the explosive growth of data traffic in the whole business to the traditional transmission network,this thesis proposes to alleviate the pressure of the whole business by adjusting and optimizing the existing network structure and networking mode.This thesis takes wuxi local transmission network and jiangsu dry transmission network as engineering cases and gives detailed implementation details.Firstly,combined with the carrying capacity required by the whole business operation,demand analysis was conducted to explore the optimization of resource allocation.Secondly,the existing transmission network structure is optimized by optimizing the hierarchical networks of the transmission network,such as the single and double connection of the backbone layer and aggregation layer,cross-networking,micro-grid adjustment of access layer and layering of the provincial dry PTN network to improve the carrying capacity of the network.Finally,this thesis presents the optimization and adjustment schemes of OTN,PTN,PON and other important systems in local and provincial transmission networks,and achieves the effect of optimizing the structure of the existing transmission network transmission system. |
