A Publish-Subscribe Networking Architecture for Future Manned Deep Space Exploration

摘要

With the further development of the Deep Space Networking(DSN),more and more satellites and space probes will be put into space which makes the DSN more diverse and complex.We argued that Information Centric Networking(ICN)may be a suitable architecture for the DSN.In this paper,a publish-subscribe networking architecture based on ICN is proposed for future manned deep space exploration network.It adopts the publish-subscribe mechanism and decouples the control plane and data plane logically.In the proposed architecture,the improvement of routing is made to tolerant the long propagation delay and frequent link disruptions of deep space.And the multi-source transmission is considered to deal with the large amount of data in the future manned deep space exploration network.We evaluated the feasibility of the architecture and the performance of the protocol stack,the improved routing mechanism and the multi-source transmission.The results indicate that Publish-Subscribe Networking(PSN)can cope with the harsh transmission conditions,and the multi-source transmission can reduce the delivery time of data.It enables the network to allocate and share resources more efficiently and keeps the network well managed.
