This document describes the Licklider Transmission Protocol (LTP) designed
to provide retransmission-based reliability over links in challenged
internet environments exhibiting extremely long message round-trip times
(RTTs), frequent interruptions in connectivity, and high bit error rates.
Since communication across interplanetary space is the most prominent
example of this sort of environment, LTP is principally aimed at supporting
applications in other environments as well. In an Interplanetary Internet
setting deploying the Bundling protocol being developed by the Delay
Tolerant Networking Research Group, LTP is intended to serve as a reliable
convergence layer over single hop deep-space RF links. LTP does ARQ of data
transmissions by soliciting selective-acknowledgment reception reports, is
stateful, has no negotiation or handshakes, and supports
out-of-transmission-order data delivery.
