Support your design choices by evidence — RTaW-Pegase computes performance metrics such as network loads, communication delays and buffers utilization that make it possible to predict network performances under all scenarios. In addition, RTaW-Pegase offers features to compare different design and configuration options – learn how RTaW-Pegase assists you throughout the entire development cycle.

Reduce time-to-market — our unique ZeroConfig-TSN® (ZCT) generative design algorithm cut the development time of TSN networks by a factor 30 and more. Interested to see ZCT at work? Contact the product manager for a demo.

Cost-optimize your networks — RTaW-Pegase enables you to avoid over-provisioning of resources (link speeds, memory in switches, unneeded technologies, etc). In addition, RTaW-Pegase includes design space exploration algorithms to optimize network topologies (e.g., number and location of switches), data streams routing and allocation of the software functions on the stations. The built-on cost models allow you to compare the cost-performance trade-offs of the candidate designs – see this study for an illustration.

Design for the future — with our unique Topology Stress Test® (TST) function, you can predict the extent to which your networks will be able to sustain increased traffic. Interested to discover how TST can assist you in designing a future-proof network? For a demo, please contact the product manager, or download this study.
