1. Connext DDS is a connectivity platform that uses publish/subscribe middleware to loosely couple systems and reduce lifecycle costs through interoperability. 2. It supports mission-critical real-time systems with low latency, high throughput, and resilience through features like redundant networks and failover. 3. Connext DDS has been proven in over 850 critical systems in aerospace, defense, transportation, energy and other industries.

12. Example: US Army Asset Tracking System
Legacy Capability:
• 500K lines of code
• 8 yrs to develop
• 21 servers
• Achieved: 20K tracked
updates/sec, reliability
and uptime challenges
With Connext DDS:
• 50K lines of code—order
of magnitude less
• 1 yr to develop—8x less
• 1 laptop—20x less
• Achieved: 250K+ tracked
updates/sec, no single
point of failure
“This would not have been possible with any other known technology.”

13. Significant Potential Cost Savings
Certification Cost Savings Based on
Lines of Code Saved with Connext DDS
30,000 ELOC 20,000 ELOC 10,000 ELOC
Level A $3,000,000 $2,000,000 $1,000,000
Level B $2,550,000 $1,700,000 $850,000
Level C $1,800,000 $1,200,000 $600,000
• Connext DDS certification evidence available
at fraction of cost
• Availability at start of project also reduces risk
