Design And Implementation Of A Virtual Server-Based Cell Cloud Network

Since the era of mobile Internet access,for the limitation of hardware,single devicebased pattern for entertainment and work is grandually unable to meet the demond of residents nowadays.In recent years,with the emergence of multi-screen interaction techenic,household smart teminals could provide multiform of entertainment methods by combining as a whole.In addition,for the increasing popularity of cloud computing,using virtual machine on the cloud to replace the role of personal computer in the scene of multi-screen interation has become a novel trend of cloud service.Whereas as the consequence of growing quantity of household smart terminals,there is a conflict in bandwidth resource between common Internet service of residents and cloud service metioned above,which would have a negative influence on user experience for Internet service.Noted that there is an increasing trend that fiber optic network has become the first choice for residential access network recently,so the proposal of the network structure which could take advantage of fiber optic network and support the new form of the cloud service for mulit-screen interation has a certain market value.Faced the demand mentioned above,this article proposes a method which could balance the efficient of fiber optic access network and the functioning of inner-cell cloud service.Furthermore,to satisfy the demand for the dynamic management of the quality of service(QoS)for virtual machine of resident,this article proposes a software defined network(SDN)based flexible bandwidth strategy which focus on user level of inner-cell cloud service and provides a certain level of fairness.Besides,for the consideration of management and security of inner-cloud service,this article presents a simple access control policy to assist existing security method of cloud service.Firstly,this article introduces background and significance of the issue and makes a brief description of research status of SDN and QoS of fiber optic network.Secondly,this article makes a basic introduction of the technic related to main issue,and makes the decision to use Ryu controller and Mininet as tools for simulation implementation.Thirdly,the requirement analysis is presented and the functions which the system should provide are listed.Furthermore,a detailed design for lower network structure and virtual network management is presented according to requirement analysis.And then,the simulation implementation and functional test for strategies and function are processed.The consequence of test indicates that the simulation implement of virtual network management and the construction of lower network structure could meet the demond which mentioned in requirement analysis.Finally,a brief conclusion of the issue and prospect of further work is made.
