Trialog Libraries Approach
Library tested on
thousands of test cases
• ensures interoperability
• eases development
• short time to market
• ensures compatibility
PC
A library includes
the FULL EHS Protocol
Only the necessary part of the
protocol is included in a node
Trialog EHS Technology
The Library Approach Avantages
To address :
• Technology dimensions
• Evolution of specification
• Interoperability and Conformance
• Reliability / Performance / Optimisation
