Time Critical Networks

Build low-cost deterministic Ethernet systems Switched Ethernet for time-dependant applications May, 2012

Ethernet are more & more demanding Less critical Semi-critical Critical

Challenges with Standard COTS Ethernet • Preconception of low level of determinism – Hesitant to use COTS Ethernet for time- dependant services • Demand for costly non-standard Ethernet solutions – Proprietary solutions *Definition of Standard COTS Ethernet: – Based on Commercial Off-The-Shelf (COTS) Ethernet hardware – Uses standard software stacks (IEEE802.3) – Uses only hardware features that are supported by all Ethernet switches

100 % Quality of Service • Guarantee Quality of Service close to 100% – For the most valuable software applications in the network • Quality of Service = Determinism – Latency • Set deadlines on response times – Jitter • Set limits on network disturbance and interference – No packet-drops • Make sure no packets are lost

Unique & patent-pending technology • Virtual System Platform – Model-based network design • Create strong and robust constructions – Based on fulfilled service levels of latency, jitter and packet-drops – Optimize the network or system • Analyze and Verify – Change switches, links, application flows, priorities and see the results Based on years of research in real-time embedded systems (schedulability analysis)

TCN Real-time Modeling & Verification Suite Verify ModelConcept System • TCN TimeAnalyzer™ – Model based network design and analysis • TCN StreamAnalyzer™ – Test and verification of real network performance

Standard COTS Ethernet + TCN* is the key differentiator Price/MB Low Ethernet + TCN Medium High Determinism Low Medium High *Time Critical Networks

Ethernet + TCNEnabler for a new market Time Critical Networks unique technology is an enabler for switched COTS Ethernet for time-dependant applications
