A Novel Network Management Architecture for Self-organizing Network

In this paper we presented novel distributed network management architecture for self-organizing network to overcome disadvantages that come along with central management approach, like lack of reliability and scalability. By introducing the distributed network agents (DNA), the proposed framework self-organizes and maintains an overly which can fulfill the autonomic communication, and achieve diverse service of management application. Under the proposed architecture, we design and put forward an effective flow-based intelligent system for traffic identification and classification, which provides sound foundation for traffic shaping and control, and for further reasonable accounting as well. So far, little attention has been paid to user-perceived quality of service (QoS). Our self-organizing management overlay addresses the issue and provides a reliable and scalable basis for end-user QoS monitoring and the performance management. Furthermore, performance analysis and modeling in terms of overall waiting time from users' viewpoint are presented. Incidentally, the model can be used to evaluate the self-organizing DNA overlay performance as well.
