Application Scenarios

Used for more than 10 years in the automotive, aerospace and industrial sectors by a wide range of customers, including Airbus Group companies, ArianeGroup, Mercedes-Benz, Bosch, Huawei, ABB, etc. RTaW-Pegase is the most comprehensive design tool for time-sensitive networks (TSNs) over critical Ethernet. RTaW-Pegase is the most comprehensive design tool for time-sensitive networks (TSN) over critical Ethernet.

  • Modeling, configuration, visualization, design analysis;
  • Local support for variant management and comparison of design alternatives in terms of performance and cost;
  • The result panel shows the calculated maximum communication delay, where red color indicates that the timing constraints for the given data stream cannot be guaranteed. The zero-configuration TSN® provides you with a solution to this problem.

How can RTaW-Pegase help you design a secure and optimized network?

Future-proof design

With our unique Topology Stress Test® (TST) feature, you can predict how well your network will be able to handle the increased traffic.

Support your design choices with data

RTaW-Pegase calculates performance metrics such as network load, communication delay, and buffer utilization to predict network performance in all scenarios. In addition, RTaW-Pegase offers the ability to compare different design and configuration options

Reduced time to market

Our unique ZeroConfig-TSN® (ZCT) generative design algorithm reduces TSN network development time by a factor of 30 or more

Optimize your network at low cost

RTaW-Pegase enables you to avoid over-allocation of resources (connection speeds, switch memory, unneeded technologies, etc.). In addition, RTaW-Pegase includes the design of spatial exploration algorithms to optimize network topology (e.g., number and location of switches), data stream routing, and allocation of software functions on the space station.

Trusted data results

RTaW-Pegase relies on network calculus accepted in aviation certifications, and its core algorithm is fully detailed in the referenced scientific publication
