Time Critical Networks
- 1. Build low-cost deterministic Ethernet systems Switched Ethernet for time-dependant applications May, 2012
- 2. Ethernet are more & more demanding Less critical Semi-critical Critical
- 3. 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
- 4. 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
- 5. 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)
- 6. TCN Real-time Modeling & Verification Suite Verify Model Concept System • TCN TimeAnalyzer™ – Model based network design and analysis • TCN StreamAnalyzer™ – Test and verification of real network performance
- 7. Standard COTS Ethernet + TCN* is the key differentiator Price/MB Low Ethernet + TCN Medium High Determinism Low Medium High *Time Critical Networks
- 8. Ethernet + TCN Enabler for a new market Time Critical Networks unique technology is an enabler for switched COTS Ethernet for time-dependant applications

Hinweis der Redaktion
- Ethernet is far the biggest network standard in the world and is expanding into further time-critical, or at least time-dependent, segments. Currently Industrial Ethernet has a global market size of about 900 million Euro (2010) growing exponentially with 30 % anually 2 billion Euro is 2010 estimated only to software design and analysis of automotive industry
- Huvudbudskap: Standard Ethernet superior in price/performance – but lacking determinism You are not sure if it will work.
