How will RTaW-Pegase help you design of safe and optimized networks?

  • 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.
  • Results you can trust — RTaW-Pegase relies on Network Calculus, which is accepted in aeronautics certification, and its core algorithms are fully detailed in refereed scientific publications – check 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.

  • Rich graphical edition and visualization environment with communication architecture editor, Gantt diagrams, and comparison of design options,
  • Easy import and export of network configurations and simulation results through Java export plug-ins, CSV, XML, YANG (IETF/IEEE) files and other common formats used in the industry,
  • Maximum pessimism of the computed communication latencies with regard to the true worst-case latencies is limited (typically less than 15%) and is evaluated for each data stream,
  • Include NETAIRBENCH, a benchmark generator to create random yet realistic Ethernet configurations for early stage evaluation or to study how the network will be able to accomodate more load in future evolutions,
  • Extremely fast – for instance, large AFDX networks in civil airplanes are analysed in less than 10 seconds,
  • Runs on all 32 or 64 bit platforms supporting Java – perpetual and subscription licensing models,
