Abstract
Boarder Gateway Protocol (BGP) is mainly used for inter-domain routing in terrestrial internetworking. However, when the traditional BGP is used for space internetworking, inter-domain link interruption might occur more frequently and the time of routing convergence will tend to be long, which would greatly reduce the stability of the network. A new variant of border gateway protocol, N-BGP is proposed in this paper for space internetworking. Firstly, the existing NTD-BGP method are adopted in N-BGP to deal with predictable link changes caused by orbital dynamics of satellites. For the unpredictable link break, BGP finite state machine is modified and a new link break detection mechanism is also introduced. Considering the predictability of satellite motion, the backup routing mechanism is also used to maintain the stability of the network, which realizes the high stability of inter-domain routing. The experimental results show that the improved routing protocol N-BGP is superior to the traditional BGP in reducing the detection time of link interruption and maintaining the network stability.
