The Investigation On Fusion Scheme And Key Technology Of Fibre Optical Communication Private Network And Public Network

With the advent of the information age,the promotion of network convergence is of great significance to the adjustment of industrial structure and the development of electronic information industry.Network convergence has risen to the height of our national strategy.Private networks such as electric power,transportation and aerospace are of considerable scale nowadays,having many similarities with traditional network information platforms such as telecommunication network,computer network and radio and television network in information infrastructure.This makes the integration of private networks such as electric power,transportation,aerospace and Telecommunications public network in infrastructure field become the best combination point of integration and development.However,network convergence is still in its infancy,and the diversification of network element devices also affects the convergence process between private networks and public networks.In this paper,aiming at the more effective and rapid construction of network convergence,the research on the scheme of network convergence between Hainan Telecom Network and Power Communication Private Network is carried out.The simulation of the scheme is realized through OPNET,the convergence scheme and verification results are obtained.In this paper,the scheme and key technologies of integration between private optical fiber communication network and public network in Hainan Province are studied.The main research work and achievements are as follows:1.The three-tier architecture model of SDN software definition network is studied,so is the significance of SDN to solve the bottleneck problem of traditional network.The programmable features brought by Openflow protocol for the network are discussed.The above works provide a theoretical basis for network convergence scheme design.2.Based on IP bearer network technology and SDN technology,through the connection of two network SDN switches,a scheme of integration and complementarity between Hainan telecommunication network and power communication private network is designed.It conforms to the principle of reducing duplication of construction,reusing existing network element equipment as much as possible,and uses SDN to efficiently manage different types of network elements,realizing flexible and effective network management.3.The network convergence model of OPNET simulation software based on discrete simulation mechanism and three-tier architecture model is designed.The three-tier architecture of process model,node model and network model is built.Five convergence scenarios are set up,and the corresponding network services and user behavior are configured.The simulation experiment of the convergence scheme is carried out.Finally,the test results are compared and analyzed to verify the feasibility and efficiency of the proposed network convergence scheme.
