Design, implementation and optimization of network access control system based on routing diffusion

Traditional network access control approaches are inflexible and low efficient, so they cannot be deployed in large-scale network. This paper presents a new network access control system (NACS) based on routing diffusion. Then this system has been designed and implemented. Then two key optimization programs-parallel router and tunnel technology-are proposed to improve the performance of NACS. At last, a large number of experiments are given to verify its high efficiency.
