Research On Key Technologies Of Large-scale Target Network Construction In Cloud Edge Architecture

The network communication technology is constantly evolving and developing with the changes in the network space.The number of access devices in the network space has increased dramatically,resulting in the continuous expansion and complexity of its scale and structure.Various network technologies for new network environment,such as communication protocol,algorithm,network architecture,etc.,must be strictly tested before being put into application.The expansion of network scale and the complexity of network structure promote the emergence of edge cloud computing,which provides a new experimental platform for network simulation.Based on the cloud edge architecture platform,this paper studies the key technologies of large-scale target network construction.The key technologies of large-scale target network construction under cloud edge architecture mainly include two parts: one is the automatic deployment technology of virtual network topology,the other is the simulation technology of virtual network link characteristics.Based on the cloud edge architecture platform,the virtual network topology automatic deployment technology has designed the virtual network automatic deployment framework,it has implemented the simulation of virtual network in three simulation layers: full virtualization,lightweight virtualization and simulation layer,which achieve a high degree simulation of the target network in terms of network topology,network scale,and node simulation degree,and achieves a balance in simulation effect,deployment scale,and deployment performance.Then,for thedifferent levels of simulation networks,a user-defined virtual routing node is designed to achieve the connection between different levels of network and integrate all parts of the target network.According to the three characteristics of network delay,packet loss rate and bandwidth,the simulation technology of link characteristics analyzes the influence of the original error of the link on the simulation effect,and then puts forward the corresponding simulation accuracy improvement algorithm,which is used to reduce the error in the link simulation,so that the simulation result can reach the target value more accurately,and the characteristics of the virtual link can be closer to the real physical link The situation.The above key technologies combine with each other to form a network simulation platform of cloud edge architecture,which can support target network deployment of various structures and scales,and simulate the link characteristics according to the needs to be close to the real physical link,with high abstract ability.The platform can provide experimental environment for various application scenarios and research fields,and has broad application scenarios and research value.
