Abstract: The Cloud Computing calculate the duty to distribute on the resource pool which the massive computers constitute, enables each kind of application system according to need to gain the computation strength, the storage space and all kinds of software service. Cloud computing offers reduced capital expenditure, operational risks, complexity and maintenance, and increased scalability while providing services at different abstraction levels, namely Software-as-a-Service (SaaS), Platform-as-aService (PaaS), and Infrastructure-as-a-Service (IaaS). However, when networking aspects for distributed clouds are considered, there is little support and the effort is often underestimated. A new approach called cloud networking adds networking functionalities to cloud computing and enables dynamic and flexible placement of virtual resources crossing provider borders. This allows various kinds of optimization, e.g., reducing latency or network load. However, this approach introduces new security challenges. Cloud networking aims at providing on-demand elastic network services to connect existing data centre based cloud infrastructures across wide area networks. This paper presents new the cloud networking Architecture and presents a security architecture that enables a user of cloud networking to define security requirements and enforce them in the cloud networking infrastructure
