Policy-based 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 mentioned. Some related standards and products are introduced, and the future trend is estimated.

Data mining is a new hot research subject in the database field. However, in general, data mining acquires knowledge from large quantities of data. In this paper, we discuss a new knowledge discovery from database algorithm based on genetic algorithm, called GAKDK (genetic algorithm based knowledge discovery from knowledge). This algorithm is based on the crossover and mutation between knowledge trees. It can retrieve undiscovered knowledge from raw rules.
