Abstract
The highly successful architecture and supporting protocols of today’s Internet operate poorly when faced with operating environments such as very long delays, excessive loss, network partitioning, or short node lifetimes. Such properties are typically found in extreme environments which lack infrastructure or operate under severe constraints such as limited power. To achieve interoperability between such networks, a network architecture and application interface structured around message switching, one-way delivery paths, and limited expectations of end-to-end contemporaneous delivery is suggested. The architecture is intended to operate as an overlay above the transport layers of the networks it interconnects, and provides key services such as innetwork retransmission, interoperable naming, authenticated forwarding and a coarse-grained class of service delivery. The existing TCP/IP based internet operates on a principle of providing end-to-end inter-process communication through a concatenation of dissimilar link-layer technologies. End-to-end connectivity is enabled by the standardization of the IP protocol and its mapping into link-layer data frames at each router as required. Although often not explicitly stated, a number of key assumptions are made regarding the overall performance characteristics of the
