Abstract:

   This document describes a UDP convergence layer (UDPCL) for Delay-
   Tolerant Networking (DTN).  This version of the UDPCL protocol
   clarifies requirements of the earlier experimental RFC 7122, adds
   discussion of multicast addressing, congestion signaling, and updates
   to the Bundle Protocol (BP) contents, encodings, and convergence
   layer requirements in BP version 7.  Specifically, the UDPCL uses
   CBOR-encoded BPv7 bundles as its service data unit being transported
   and provides an unacknowledged transport of such bundles.  This
   version of UDPCL also includes security and extensibility mechanisms.
