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.

this document, please see YANG Tree Diagrams [RFC8340].

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
