A policy based networking architecture for enterprise networks

We describe a new concept for policy based systems management (PSM) and propose its component functions. PSM aims to reduce the total cost of ownership (TCO) while providing highly functional enterprise systems that include enterprise networks. Conventional enterprise systems have been managed manually by humans, and are not able to provide a highly functional service with low TCO. For this reason, the policy based networking (PBN) approach is gaining attention. This paper describes the PSM that extends PBN for total systems management and shows the effectiveness of PSM functions with an example of dynamic QoS configuration.
