             Implementing Interfaces to Transport Services
                        draft-ietf-taps-impl-02

Abstract

   The Transport Services architecture [I-D.ietf-taps-arch] defines a
   system that allows applications to use transport networking protocols
   flexibly.  This document serves as a guide to implementation on how
   to build such a system.
