Policy-based network management

Abstract

Policy-base network management is a new solution set that enables business-critical applications to perform at specific levels for specific users. It implements a set of rules and policies that further an organization's business objectives by dictating how users, applications, and organizations can access and use network resources. At first, this paper describes a variety of difficulties for today's network managers. Then the policy model and a kind of policy server architecture are presented. The benefits and drawbacks of this paradigm are also concluded. Some related standards and products are introduced, and the future trend is estimated in the end.
