How RTaW-Pegase will help you design of safe and optimized networks?
Support your design choices by evidence — RTaW-Pegase computes performance metrics such as networks loads, communication delays and buffers utilization that make it possible to predict network performances in all use-cases. In addition, RTaW-Pegase offers features to investigate specific scenarios and compare the impact of different design and configuration options.
- 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.
- Design for the future — you can know in advance the extent to which your networks will be able to support additional traffic thanks to our unique Topology Stress TestⒸ (TST) feature. Interested to discover how TST can help you? Contact the product manager for a demo.
- Results you can trust — RTaW-Pegase relies on Network Calculus that is accepted in aeronautics certification, its core algorithms are described in a formal manner in refereed scientific publications – see the technical papers co-authored with our partners.
- Proven in use — leading companies from the automotive, aerospace and industrial domains have been relying on RTaW-Pegase for their business since 2009 – see the companies that trust us.
