A Multilevel Policy-Based Network Management System for Differentiated Services Network

Policy-based network management is a flexible, automatic and promising paradigm for network configuration management. The IETF has developed several specifications for policy-based configuration management. However, recent research seldom focus on a comprehensive solution for several core issues such as the rationality of the levels of the policies, the consistent relation between the policies and the architecture of the higher-level business management system, and the implementation of the multilevel policies. In this paper, a multilevel policy-based network management system for Differentiated ser-vices network is presented. The focus of the paper are the structure of the multi-level polices that is consistent with the architecture of the network management system, the policy storage and the policy processing that are independent of the individual devices, and Java implementation of the policy rules.
