1.  Introduction

   There is a need for standard mechanism to allow the specification and
   implementation of the transactions part of network tests.  The
   mechanism should allow the control and monitoring of the data plane
   traffic in a transactional way.  This document defines YANG modules
   for test traffic generator, analyzer and internal interface loopback.

1.2.  Problem Statement

   Network interconnect tests require active network elements part of
   the tested network that generate test traffic and network elements
   that analyze the test traffic at one or more points of its path.  A
   network interconnect tester is a device that can either generate test
   traffic, analyze test traffic or both.  Here is a figure borrowed
   from [RFC2544] representing the horseshoe test setup topology
   consisting of a single tester and a single DUT connected in a network
