Design: Criteria and Encoding

  • Medium independence

  • Collision/reflection avoidance: bit length longer than net

  • Simplicity

  • End-to-end modulation

UDP, TCP

IP

SLIP

ASCII

Application support

Application Support

  • THTP

    • Single packet payload only

    • Minimum HTTP support: GET, POST, reply, extremely limited error msgs

    • Standard HTTP format

  • Scalable encryption: basis for authentication, privacy, integrity


Looking forward

Looking forward

  • Federation:

    • Multiple Internet Ø nets interconnected: how to allow individual nets retain simplicity

    • Integrating Internet Ø nets with larger Internet

  • Commercial potential: device, power and control, networking, building industry

  • Services, functionality, support structure between THTP and applications
