Construction Of Security Domain System Based On SDN In Cloud Computing Environment

In recent years,the leap development of Internet technology and business,cloud computing,virtualization,big data technology has become the field of information art,on this classic network also brings forward many challenges.Mobile cloud computing security resource pool in the continuous development of cloud technology and virtualization,but also thinking of cloud based security construction,this paper focuses on cloud resource pool as a platform to study the construction of new security system.This paper first proposed the cloud resource pool construction safety principle and key construction planning.On the plan,etc.,to the end of credible,5 principles of maximum security and scalability,security domain system construction to support the construction of the new data center network(SDN network architecture),increase the application of virtualization technology with automatic operation and management.To implement the detailed construction plan,issued detailed planning of cloud resource pool construction network,including core domain,resource pool,Internet interface sub three parts,at the same time,according to the theoretical research and feasibility assessment,according to the characteristics of the three domains were carried out to implement innovative landing.In the process of virtualization,SDN(Software Defined Network),NFV(Network Function virtualization)development of three hot technologies were described,the construction of the security domain system based on these three technologies,profound description of supporting technology of new cloud resource pool security domain construction,and puts forward the cloud data center north-south traffic protection and realization method of flow protection to things.Through the above ideas to guide the project in the concrete realization of the concrete floor construction of cloud security domain system based on SDN computing environment.Finally realized the resource pool of cloud computing environment and the separation at the technical level,the general function of hardware,software,network flat,new functions can be quickly deployed based resource virtualization,resources can be dynamic and smooth expansion functions;in the operation and maintenance level is to achieve a full access,management mode,improve the operation mode,saves the cost.
