Research on the Policy-Based Satellite Network Management

In order to accomplish the self-management of the satellite network, policy is introduced into the network management and a new policy-based hierarchical distributed architecture is established in which two new policy layers called domain policy server and local policy server are added between policy enforcement point and global policy server to share the management tasks for the center management station. Furthermore, this paper defines the policy structure with XML schema and describes policy with XML. The simulation results show that the new architecture improves the efficiency of the network management.
