Research On QoS For Space-Ground Networks

摘要：

This paper proposes the complete QoS(Quality of Service) architecture for integration of space network with infrastructure networks. The technology, service differentiation mechanisms, network control mechanisms and user-to-networks mechanisms are discussed. The modules required in the network elements and its integration to provide end-to-end QoS in Space networks are presented. The proposed solution is based on the Diffserv architecture with some extensions to provide L2 differentiation for four traffic classes and supports the integration with infrastructure networks. The deployed hierarchical architecture guarantees scalability and make possible per-flow resource management in satellite access where scarce radio resources should be managed effectively, and per-aggregate traffic management using a DiffServ model in the core.
