Framework for distributed real-time access systems

3rd edition, June 2019

This Standard specifies a framework for a distributed real-time access system.

It includes:

  • an ID triggered modular system architecture, the functions of the modules, the semantics of messages those modules exchange, and elements of messages;
  • the system behaviour from the time it receives an access request until the time it sends the result along with the sequence;
  • performance measurement mechanisms using a time stamping function that can be employed for the evaluation of the system.
