Datagram Convergence Layers for
the Delay- and Disruption-Tolerant Networking (DTN) Bundle Protocol
and Licklider Transmission Protocol (LTP)
Abstract
This document specifies the preferred method for transporting Delay-
and Disruption-Tolerant Networking (DTN) protocol data over the
Internet using datagrams. It covers convergence layers for the
Bundle Protocol (RFC 5050), as well as the transportation of segments
using the Licklider Transmission Protocol (LTP) (RFC 5326). UDP and
the Datagram Congestion Control Protocol (DCCP) are the candidate
datagram protocols discussed. UDP can only be used on a local
network or in cases where the DTN node implements explicit congestion
control. DCCP addresses the congestion control problem, and its use
is recommended whenever possible. This document is a product of the
Delay-Tolerant Networking Research Group (DTNRG) and represents the
consensus of the DTNRG.
Status of This Memo
