DSRC协议的LLC子层状态转移分析

State Analysis of Logic Link Control Layer of Dedicated Short Range Communication Protocol

本文分析了智能交通(ITS)领域中使用的专用短距离通信(DSRC)协议的基本协议结构、LLC子层的主要功能及其服务类型,并着重论述了LLC子层的协议进程,画出了相应的有限状态转移图,为数据链路层的进一步开发做了基础性的工作。

This paper describes the elementary concept and system structure of the Dedicated Short Range Communication Protocol(DSRC). It also introduces the main functions and service types of logic link control layer, and presents state charts of logic link control (LLC). The research lays a foundation for the development of the Data Link Layer of DSRC protocol.
