RFC 7122 Title: Datagram Convergence Layers for the Delay- and Disruption-Tolerant Networking (DTN) Bundle Protocol and Licklider Transmission Protocol (LTP) Author: H. Kruse, S. Jero, S. Ostermann Status: Experimental Stream: IRTF Date: March 2014 Mailbox: kruse@ohio.edu, sjero@purdue.edu, ostermann@eecs.ohiou.edu Pages: 11 Characters: 25889 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-irtf-dtnrg-dgram-clayer-05.txt URL: http://www.rfc-editor.org/rfc/rfc7122.txt 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.
