Research on a New Architecture of Satellite Network Management

The characteristics of the nodes´ high-dynamic and long transmission delay between the satellites and terrestrial station lead to the difficulty in managing the satellite network. So this paper proposes a new dynamic-layered management architecture based on the researches of the traditional policy-based network management architecture. In the new architecture, domain policy decision point (Domain PDP) and local policy decision point (local PDP) are added between policy enforcement point (PEP) and traditional policy decision point (PDP). Domain PDP and local PDP are dynamically deployed in the sub-management stations and the satellite agents with management functions. Simulation results show that the new architecture reduces the amounts of the communication between terrestrial station and satellite agent which makes the network management efficiently.
