Abstract

This thesis aims to study and present network management policies. As a network management, we consider the IT process that deals with the operation, management and monitoring of data. Policy-based management is a technology that can simplify the complex task of managing networks and distributed systems. According to this example, an administrator can manage different aspects of a network or distributed system in a flexible and simplified way by developing a set of policies that govern its behavior. Policies are technology-independent rules designed to enhance the encoding of managed device functions by introducing interpreted logic that can dynamically change without modifying the underlying implementation. The work is divided into 3 chapters. In the Introduction, a brief description of the very basic concepts, which are necessary for a better understanding of how different management policies work, is made. Basic concepts such as Network, Network Management, and Policy Based Network Management are outlined. The first chapter presents and analyzes the components of political network management. Initially, the reasons for the need to implement management policies in the networks are discussed and then basic concepts such as policy conflict, wrong policy and policy analysis are analyzed. The second chapter presents existing network management models, based on policies such as the IETF (Internet Engineering Task Force) PEP model, Ponder2, and Kaos. Also presented are the issues of security and quality of service of the networks they manage on the basis of policies. The third chapter is a description of a case study on the implementation of networks based on policy, by Hare and others. The case study describes the problem of allocating limited data volume to bus passengers and how this could be shared on the basis of needs and applied management policies. The last chapter is the summary and future developments of network management policies.
