Access control capable integrated network management system for TCP/IP networks

This paper is on the functional architecture for the access control capable policy based network management system for TCP/IP enterprise networks. The network management system structures proposed in this paper works in parallel with the policy based real-time access control function to make the utmost use of the network resources and to provide a high-quality service to the user which is distinguishable to the network management policy for simple network infrastructure. This paper illustrates an effective interface and interworking functions among the policy server, the access control server, and the network management server. With the proposed policy based network management system, the network operator can recognize network problems in real-time and can effectively figure out how the network infrastructure should be reconfigured in order to resolve the problems.
