Research And Implementation Of Collaborative Communication Distribution Technology In Mobile Cloud Computing Environment

With the maturity of 5G communication technology,the technology of mobile cloud computing is changing with each passing day.The core of mobile cloud computing is the mobile Internet to obtain the computing,memory,and application delivery of the underlying platform on-demand.By delivering data processing services and storage services that require physical hardware support to the server,the computational requirements of the CPU and the storage capacity in the client are alleviated.Due to the obvious advantages of mobile cloud computing,a variety of mobile cloud computing applications have sprung up,greatly enriching the service types of terminals and expanding the application scenarios of terminal.This change makes static shunting of a small number of services by using routers or firewalls in the traditional network model,which is already inconvenient in the existing mobile cloud computing environment.There is an urgent need for a dynamic and flexible management of the ”cooperative communication distribution” technology solution to achieve a large number of multi-service type traffic access requirements to ensure the quality of service when the mobile terminal side gets to the cloud server side during service access.In response to the above requirements,this thesis develops a ”cooperative communication distribution” system,which dynamically divides the available bandwidth by acquiring the available bandwidth from the terminal to the server to meet the communication service quality requirements of different services of different terminals.The whole system consists of three modules,namely management module,controller module and soft switch module.The management module is used to interact with the administrator and measure the available bandwidth and pass these configuration information to the controller module.The controller module performs secondary development on the basis of in-depth study of the open source FloodLight controller.By receiving configuration information from the management module,the classification,marking and enqueueing functions are implemented,and the flow table information is completed according to the controller.For the monitoring function of the service flow,the monitored service flow data is used as a reference measure for allocating bandwidth of each service flow.The soft-switch module is implemented based on the open source Click software platform.It uses the token allocator proposed in the CCAR layered CAR model in this thesis to redistribute the overflow token to implement dynamic bandwidth allocation of different service flows,and uses queue management and queue scheduling to implement traffic differentiation on the outbound port.The collaborative communication distribution system implemented in this thesis reduces the degree of coupling between business layers,which makes administrators more flexible in managing network devices.And through the improvement of the tiered traffic rate limit,the dynamic allocation of bandwidth is realized,thereby greatly improving the bandwidth utilization in the network.
