摘要：
Integrated terrestrial-satellite networks (ITSN) are a major project of China's "Scientific and Technological Innovation 2030" and an important development direction for the Internet. The inter-domain routing protocol is a key factor for effective integration of various satellite networks and existing terrestrial networks in ITSN. However, the network topology of satellite network changes frequently, which presents significant challenges for deployment of the existing inter-domain routing protocol. The widely used inter-domain routing protocol border gateway protocol (BGP) is used here to develop a network-topology-decoupled BGP (NTD-BGP). The protocol uses an inter-domain neighbor discovery scheme that is independent of the physical topology changes and a module for active routing updates. The protocol uses the predictability of the satellite movements to decouple the mapping between the network topology and the inter-domain neighbor relationship as well as routing updates to achieve efficient, stable inter-domain routing in ITSN. Emulations show that this protocol more effectively maintains inter-domain neighbor relationships, more effectively reduces routing update times, and more effectively maintains network stability than the traditional BGP. © 2019, Tsinghua University Press.
