Integrated Network Service to Enhance Multicast Communication

One of the features of the Software Defined Network (SDN) is to integrate network service into the network layer to better support the application and alleviate the burden of client-server end. Multicast as an efficient communication method, it can be exploited to provide more meaningful network services to applications which involve one-to-many and many-to-many communication. Traditional multicast implementation mainly emphasizes on low network overhead and its function is kept as simple as possible. This makes multicast vulnerable to misuse. However, when network service is integrated into multicast based on the architecture of SDN, the robustness and security of multicast can be enhanced. This paper proposed a detailed implementation of secure network services to enhance the whole process of the multicast communication. Furthermore, the pricing policy is also discussed for different kinds of multicast application scenarios.
