Welcome to the official home of LTP - Licklider Transmission Protocol aka Long-haul Transmission Protocol. LTP is named in honor of JCR Licklider , one of the pioneers of ARPANET who envisioned having interplanetary links a long time ago.
LTP is designed to provide retransmission based reliability of data transmissions over deep-space RF links. In the bundling protocol stack designed by the Delay Tolerant Networking Research Group DTNRG , it serves as a reliable datalink convergence layer for deep-space links.
The protocol is currently described in 3 documents :
* The motivation document : draft-irtf-dtnrg-ltp-motivation-04.txt
* The main protocol specification document : draft-irtf-dtnrg-ltp-06.txt
* The extensions document : draft-irtf-dtnrg-ltp-extensions-05.txt
The LTP interest mailing list exists here .
