Research and Implementation of Distributed Access Control and Traffic Statistics Based on XORP

In high-speed network, access control and traffic statistics which are deploied on single node router cause a sharp decline in router forwarding performance. Using extensible architecture and inter-process communication mechanism of XORP,we integrate access control and traffic statistics module into the original structure, in order to achieve a distributed access control and traffic statistics.This can reduce the load of router on access node of high-speed network.
