Overview
Project Title	Licklider Transmission Protocol for CCSDS
Approval	Approved
Document Number	734.1
Charter	6.09 Delay Tolerant Networking Working Group
Document Type	Blue
Description of Document	<div>RFC5050 requires a reliable data delivery service between overlay routers.  While CCSDS has reliable data link protocols in TC and AOS, neither is well-suited for use as a convergence layer by RFC5050.  It is likely that any Delay Tolerant Networking protocol proposed by this group will need reliability on a hop-by-hop basis.  Thus this working group will also standardize a reliable hop-by-hop data delivery service that can be used by the Delay Tolerant Networking protocol specified by this WG.  The Licklider Transport Protocol (LTP) as described in the work-in-progress http://www.ietf.org/internet-drafts/draft-irtf-dtnrg-ltp-09.txt was designed for exactly this purpose, and will be the initial focus of this part of the WG effort.</div>
