Simulation Resources from Data Communications Directory

Akaroa - Akaroa is a package for supporting the Multiple Replications In Parallel (MRIP) simulation technique to harness the computing power of a network of inexpensive workstations. Integration exists with the Ptolemy Classic ns2 and OMNeT++ simulators.

BRITE - Tool for generation of realistic internet topologies with export to several network simulators (currently ns2 JavaSim and SSFNet).

cnet - A network simulator with a GUI and targeted at undergraduate teaching. Enables experimentation with various data-link layer network layer routing and transport layer networking protocols.

J-Sim - A component-based compositional simulation environment.

NIST ATM/HFC Network Simulator -

ns2 network simulator - 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++ - OMNeT++ is an open-source component-based simulation package built on C++ foundations. It offers a C++ simulation class library and GUI support (graphical network editing animation).

Parsec - a C-based simulation language for sequential and parallel execution of discrete-event simulation models

REAL - a modular network simulator featuring a java GUI

Scalable Networks - Network simulator designed from the outset for maximum speed and scalability with real-time simulation as an achievable goal.

SSFNet - SSF (Scalable Simulation Framework) is a public-domain standard for discrete-event simulation of large complex systems in Java and C++. Several SSF implementations and a large number of open-source protocol models and other components exist.

x-sim - The x-kernel protocol framework can be used as a complete simulation environment for TCP/IP networks.
