The Network Access Control Research Based on Distributed Router

This paper based on a distributed router studies Access Control and Traffic Statistics, and gives the specific implementation method. Based on primary platform expand an Access Control Module (ACM), and implement access control and flow statistics, using rule-based matching filtering table and “Data Cube” store and optimize rules. Using its network number, host number and time-range determine whether the data packets can be transmitted through the route forwarding. It takes NetFlow technology for traffic statistics and collects the data packet of same network number to the data stream. Each data stream can be individually tracked and accurately measured, recorded the transmission attributes such as direction, destination and so on.
