There are several different features of satellites network compared to ground networks, such as long time delay, large bandwidth delay production (BDP), high error rate, intermittent and asymmetric links, etc. There are abundant research results indicated that it will reduce its performance and waste precious network resource if apply the traditional TCP in the satellites network directly. Transfer...
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...
The focus of this paper is dynamic link allocation algorithms for sharing the limited link resources of the tracking and data relay satellites (TDRS) system among many burst users with varying quality of service (QoS) requirements. The task of scheduling communications between TDRS link and spacecraft is getting more and more critical since an increasing number of spacecraft must communicate with...
The design and development of future ground-space integrated networks is one of the hot issues in space technology nowadays because of the long-link delay, high bit-error-rate, asymmetric bandwidth, intermittent links compare with the terrestrial networks. The focus of this paper is to design topology for this hybrid networks with space segments, select appropriate protocols for it and analyze its...
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...
