Space network are now become a very important and necessary complementary to the ground networks, it will extend the terrestrial Internet networks to space. However, there are still many challenges exist before the space-ground integrated networks come true, and how to transport data reliably in space networks is the very difficult one among these challenges. TCP has been a robust and efficient transport...
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...
TCP has been a robust and efficient protocol for terrestrial networks, but it does not fare very well in the space environment because of the long-link delay, high bit-error-rate, asymmetric bandwidth, intermittent links compare with the terrestrial networks. However, it does provide an excellent base for extension. The Space Communications Protocol Standards (SCPS) has proposed Transport Protocol...
Space wideband information network technology is one of the hot technologies in studying of space technology, there are many difficult technologies need to be solved, for example, technologies of the connection and communication between space and ground heterogeneous network, algorithm of mobile routing, etc. The paper does research on these problems based on IP technology of the ground network and...
