To integrate the space network with the ground network is the uptrend of the future communications, and geostationary satellites are very important nodes in the hybrid networks in which the reliable data transportation is critical. Based on this point, the paper designs the GEO satellite network topology that integrate the LEO network, MEO networks and GEO networks with the terrestrial networks. Because...
This paper proposes the complete QoS (quality of service) architecture for integration of LEO satellite 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 LEO satellite networks are presented. The proposed...
The aim of this work is to introduce a new way of transparently securing multicast services, optimized for satellite networks. Security of multicast data is becoming an important issue to operators and users of satellite networks. This paper presents a secure multicast architecture that fits well into the satellite areas. Multicast service scenarios with detailed security architecture are presented...
The aim of this work is to introduce a new way of transparently securing multicast services, optimized for space networks. This paper presents a secure multicast architecture that fits well into the space network. Detailed security architecture are presented here. This architecture accommodates link and network layer security (Internet) security systems and interworking with ground segment entities...
