What is the App Framework?

Why is the App Framework?

Current App Framework in IVI

• App Framework developed by IoT.bzh
• Developed for AGL IVI applications
• Based on JSON + WebSockets
• Communication separated between services in different
• processes
• Clients and services can be written in any language
• Heavily integrated with SMACK

App framework: the good

• Communication separated between services in different processes
• Allows common authentication between security domains
• Clients and services can be written in any language
• Portable to multi-ECU solutions

App framework: the bad

• Communication separated between services in different processes
  •  ... but is JSON + WebSockets the best transport mechanism?
  • IoT.bzh proposing to replace JSON with binary serialisation due to performance overhead
  • Not always the best signalling for every usecase
