Enhanced disruption and fault tolerant network architecture for bundle delivery (EDIFY)

Data communication challenges exist in some emerging network scenarios where an instantaneous end-to-end path between a source and destination may not exist, and the links between nodes may be opportunistic, predictably connectable, or periodically-(dis)connected. We propose an enhanced disruption tolerant network architecture to address such challenges. In this paper, we present a generalized naming convention for the enhanced DTN architecture that permits separate representations based on network topology, administrative control, physical location, and other factors. In addition, we illustrate possible system operations in this enhanced DTN architecture such as DTN neighbor discovery, gateway selection, mobility management, and route discovery.
