IP Over DTN: Large-Delay Asynchronous Packet Delivery in the Internet

The well-known DTN divides an end-to-end communication path into hop-by-hop sessions and allows asynchronous message delivery over physically delay or disruptive network environments. They have introduced Bundling, an overlay network for delay tolerant networking in its architecture, which should be globally deployed and operated with tremendous effort. This paper proposes a new DTN architecture that are more practically and easily deployable in the Internet space. The approach is IP over DTN; DTN message delivery framework works as a data link to deliver IP packets over network boundaries. The transport protocols and application protocols take asynchronous communication mode in this architecture.
