1.  Introduction

   This document describes the TCP-based convergence layer protocol for
   Delay Tolerant Networking (TCPCL).  Delay Tolerant Networking is an
   end-to-end architecture providing communications in and/or through
   highly stressed environments, including those with intermittent
   connectivity, long and/or variable delays, and high bit error rates.
   More detailed descriptions of the rationale and capabilities of these
   networks can be found in the Delay-Tolerant Network Architecture
   [refs.dtnarch] RFC.

   An important goal of the DTN architecture is to accommodate a wide
   range of networking technologies and environments.  The protocol used
