Network Simulation

OMNeT++/OMNEST is extensively used for R&D-type network simulations. Somewhat similarly to ns2, OMNeT++ has an active user community in the Academia, who created a large body of open-source network simulation models and model frameworks, from ad-hoc and wireless simulations to MPLS, Diffserv and IPv6.

Simulation models are truly component-based, allowing you to freely combine existing protocol models to form hosts and network devices. There is support for real-time simulation and network emulation as well.

Simulation frameworks over OMNeT++/OMNEST:

• INET Framework - supports ad-hoc, wireless and wired (LAN, WAN) simulations (802.11, Ethernet, TCP, IP, IPv6, OSPF, MPLS, RSVP, etc.) The INET Framework is maintained by OMNEST people, with frequent contributions from the user community.
• Cleanly programmed and extensively commented models lend themselves to experimentation with protocols and various architectures.
• Several models are ported versions of real-life networking software like the Quagga routing daemon, or the AODV-UU implementation, which guarantees simulation accuracy.
• IPv6SuiteWithINET - for IPv6, MIPv6 and wireless (802.11)
• Mobility Framework - for wireless mobile and ad-hoc networks
• NesCT - for simulating wireless motes running TinyOS
• SimSANs - for simulating Storage Area Networks

These simulation frameworks have been programmed in C++, and are distributed in source code form. With the exception of the INET Framework, these models are maintaned by people independent of Simulcraft Inc, so we naturally cannot provide any warranty for them. However, their large exposure to the Academia means that they get reviewed and bugfixed and improved by many people.
