本文档指定了分布式实时访问系统的框架。它包括: 1） ID触发的模块化系统架构、模块的功能、模块交换的消息的语义以及消息的元素； 2） 从接收到访问请求到发送结果和序列的系统行为； 3） 使用时间戳功能的性能测量机制，可用于系统评估。

This document specifies a framework for a distributed real-time Access system. It includes: 1) an ID triggered modular system architecture, the functions of the modules, the semantics of messages those modules exchange, and elements of messages; 2) the system behaviour from the time it receives an access request until the time it sends the result along with the sequence; 3) performance measurement mechanisms using a time stamping function that can be employed for the evaluation of the system.
