Short description of Time Critical Networks and it's unique technology for using switched Ethernet for time-dependant applications. Build low cost deterministic Ethernet systems.

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

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*

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