Management Research On Tenant Virtual Network In Cloud Computing

Cloud Computing is the next generation Internet service and data center, and it is also used for public utilities and on-demand computing.Cloud computing is not a totally new technology, but rather a derived concept of application and service innovation in which, multi-tenancy is one of the important issues among the core technologies of cloud computing applicatios. Tenant virtual networks is very important in the research about tenant, and it is crucial to the effective management of its cloud resources. From the perspective of the efficient management of the tenant network in this paper, proposed and designed a Role-Based Multi-Tenancy Access Control(MT-RBAC), while re-enacted the tenant virtual network management scheme(TMNet) under this mechanism. Effectively improve the processing performance and security under the cloud tenant services.The main work of this paper includes the following aspects:1.Through the study of RBAC and the analysis of permissions management needs of tenants under a cloud environment, a multi-tenant role-based access control model has been designed.2.Think characteristics about tenant virtual network management need to meet the specific needs,a SDN network structure based on Open Flow protocols and routing algorithms is proposed.3.Throughout the analysist about current cloud platform development technology, selected for the suitable development of cloud technology, and process software development operations about the proposed model and management solutions.4.In the built OpenStack cloud environment, achieve control model and network management solutions, and tested lastly.Role-based access control mechanism and multi-tenant network management scheme are proposed in this paper, it is possible to meet tenants permission assignment and network management requirements in a certain scale cloud computing environment, while also hardening the security of cloud applications to a certain extent and privacy. In the future it has a strong reference to the tenant network management in large-scale cloud environments.
