Resource allocation in the new fixed and mobile internet generation

In this paper we study the scalability issue in the design of a centralized policy server controlling resources in the future IP-based telecom network generation. The policy servers are in charge of controlling and managing QoS, security and mobility in a centralized way in future IP-based telecom networks. Our study demonstrates that the policy servers can be designed in such a manner that they scale with increase in network capacity. Copyright © 2003 John Wiley & Sons, Ltd.
