There are several challenges when communicating in space. We do not have fixed infrastructure and have long delays, the probability of high error, intermittent connectivity and disruption of the link. These challenges draw the attention for improving communication challenges in spaces technologies and networking architectures. The TCP/IP stack is not effective in handling challenging environments and has issues of compatibility with the present security protocols. An alternate solution is Delay Tolerant Networking Architectures. It specifies a bundle protocol. This protocol resides on the top of the transport layer. The Delay Tolerant Networking architecture provides information storage for a longer duration on transitional nodes. It is appropriate when encountering disrupted links, long links, and intermittent connectivity. NDN focuses on content instead of IP addresses making it a reliable and robust architecture for the future Internet. In NDN, there is no need for setting up and maintenance of steady paths between end nodes. It makes NDN suitable for network with intermittent connectivity and very large propagation delays. This paper discusses the perspective of integrating Delay Tolerant Networking with Name Data Networking.
