cnet is a network simulator
which enables experimentation with various data-link layer, network layer,
routing and transport layer networking protocols in networks consisting of any
combination of point-to-point links and IEEE 802.3 Ethernet segments. |

|
The Erlang products let you model
traffic blockage (loss), and/or queuing delays. |
|
|
GloMoSim builds a scalable simulation environment for wireless and
wired network systems. It is designed using the parallel discrete-event
simulation capability provided by Parsec. |
|
|
The Georgia Tech Network Simulator (GTNetS) is a full-featured
network simulation environment that allows researchers in computer networks
to study the behaviour of moderate to large scale networks, under a variety
of conditions. The design philosophy of GTNetS is to create a simulation
environment that is structured much like actual networks are structured. For
example, in GTNetS, there is clear and distinct separation of protocol stack
layers. |

|
NCTUns
is both a network simulator and a network emulator. |
|
|
Ns is a discrete
event simulator targeted at networking research. Ns provides substantial support
for simulation of TCP, routing, and multicast protocols over wired and
wireless (local and satellite) networks. |

OMNeT++ is a public-source, component-based, modular, and
open-architecture simulation environment with strong GUI
support, and an embeddable simulation kernel. Its primary application area is
the simulation of communication networks and because of its generic and
flexible architecture, it has been successfully used in other areas like the
simulation of IT systems, queuing networks, hardware architectures and
business processes as well. OMNeT++ is rapidly becoming a popular simulation
platform in the scientific community as well as in industrial settings.
Several open source simulation
models have been published, in the field of internet simulations (IP,
IPv6, MPLS, etc), mobility and ad-hoc simulations, and other areas. |

OPNET's suite of
products combine predictive modelling and a comprehensive understanding of
networking technologies to enable customers to design, deploy, and manage
network infrastructure, network equipment, and networked applications. In
particular OPNET Modeller is a development environment, allowing you to
design and study communication networks, devices, protocols, and
applications. |
|
|
Provides prediction of the performance behaviour of parallel and
distributed applications on cluster and grid architectures. |
|
|
QualNet is network modelling software that predicts performance
of networks through simulation and emulation. |
|
|
STARDIS is a
simulation tool developed by EDS (http://eds.com) that has been used by EDS
for over ten years for predicting the behaviour of future military command
and control systems and future communications systems. STARDIS uses an object-oriented,
event based approach to model real world entities and their communications. |

SWANS is a scalable wireless network simulator
built atop the JiST platform. It was created primarily because existing
network simulation tools are not sufficient for current research needs, and
its performance serves as a validation of the virtual machine-based approach
to simulator construction. SWANS is organized as
independent software components that can be composed to form complete
wireless network or sensor network configurations. Its
capabilities are similar to ns2
and GloMoSim,
but is able to simulate much larger networks. |
