OMNEST is a high-performance discrete-event simulation platform for R&D teams, researchers, and engineers. It is used to model complex systems such as wired/wireless networks, interconnection networks, queueing systems, cloud/HPC environments, TSN, SoC/NoC, optical networks, and in-vehicle networks. It is closely related to OMNeT++, which is widely used in the research community; the main differences described are licensing, branding, and additional components and features in OMNEST.
At the core of OMNEST is a high-performance simulation kernel written in C++. Models are built in a hierarchical, component-based way, with support for parallel simulation and compute clusters to improve efficiency for large-scale or batch simulations. The platform emphasizes open interfaces: it provides documented extension APIs, plain-text input and output formats, and states that it does not hide source code or lock down parts of the product. OMNEST can also run mixed simulations with SystemC, compiling SystemC and OMNEST modules into the same process and allowing communication through C++ method calls. The documentation also mentions integration with Matlab, HLA, external simulators, and other tools.
Commercial use generally requires an OMNEST commercial license. Companies can download an evaluation version for trial use and receive technical support during the evaluation period. Educational courses, student assignments, and similar non-commercial use cases can use the free non-commercial version, OMNeT++. A purchased license includes a 1-hour video orientation/consulting session. Public pages do not list standard license pricing, but they do list consulting rates: EUR 250/h as the standard rate, or EUR 220/h and EUR 200/h with a support plan. An INET support add-on is mentioned at EUR 1,200/license. Embedding the simulation kernel or distributing self-contained simulations may require a runtime license or a custom embedded license.
The main strengths are its broad range of supported scenarios and suitability for deep R&D work. Its C++ kernel and parallel simulation capabilities are favorable for performance. SystemC integration, INET, and the OMNeT++ communityβs models and case resources also strengthen the ecosystem. Developer-level support, training, and consulting are available. The drawbacks are that the system is complex and has a relatively high learning curve; commercial licensing can be nuanced and may require discussion with sales; standard license pricing is not transparent; and INET support has scope limitations for third-party modules and certain domain-specific issues.
OMNEST is well suited to R&D teams in enterprise networking equipment, automotive, aerospace, semiconductors, cloud/HPC, industrial Ethernet, and related fields. It is also suitable for product teams that need to embed a simulation engine into their own software. The available information does not specify access or payment options from mainland China, so these remain unknown. If access is unstable, alternatives or complementary tools such as OMNeT++, ns-3, MATLAB/Simulink, and AnyLogic may be worth considering.
