North-East Pacific Undersea Network Experiments (NEPTUNE) is a multi-node cabled ocean observatory linked by 818 kilometers of powered fiber optic cable off-shore
from Vancouver Island across the northern Juan de Fuca tectonic plate. It includes
a Data Management and Archive Station (DMAS) at the University of Victoria (UVic)
and a shore station at Port Alberni, BC, Canada. The core of the
network consists of 6 branching units, 6 node stations, 13 junction boxes and more
than 130 instruments.
In this paper, we explore the costs and benefits of constructing a simulator for
NEPTUNE using the OMNeT++ simulation platform---a C++ based discrete-event
simulator. In this context, we present the design and implementation of a simple
simulator that can work with a variety of configurations of instruments, where
the instruments are connected to DMAS via junction boxes and branching units, and
generate TCP and UDP traffic following certain patterns. The simulator is
designed for supporting \emph{what-if} scenario analysis, particularly with
respect to system evaluation and discovery of limits associated with network
traffic behaviors. Our study reveals that, although building the simulator in
OMNeT++ has many advantages such as ease of tuning and calibration, capturing
sufficient details regarding the working behavior of the actual NEPTUNE
environment is still challenging. A survey of alternative tools, including
NS-2/NS-3, OPNET, JiST/SWANS, J-Sim, SSFNet, and Qualnet reveals that these
nuances would not be any less challenging within these simulation environments. / Graduate
