| We discuss a new approach in Policy-Based Management (PBM), which can realize end-to-end Quality of Service (QoS) for all connections across the Internet. The design is based on a reference PBM standard and its supporting communications protocols. These protocols are Common Open Policy Service (COPS) and Lightweight Directory Access Protocol (LDAP). Our proposed model is designed to work with active networks technology. In contrast to the traditional network, an active network is able to manipulate data in the packets, and change the network functionalities on a per-user and application basis. Our proposed framework, the Active Bandwidth Broker (ABB), delivers an easily maintainable, mobile and load sharing architecture for policy control. Our goals are to achieve a distributed PBM framework to improve scalability, and to introduce a mobile mechanism to enhance the availability of the service. This results an intelligent network that is incorporated with QoS control to generate performance protection for voice, video and Internet business applications. |
