信息和通信技术行业内出现了各种通用数据分发技术。这些技术通常在开放系统互连（OSI）会话层、表示层和应用层（即第5-7层）提供服务。在智能交通系统（ITS）中，这些层大致对应于ISO 21217中定义的ITS站点（ITS-S）参考体系结构的设施层。 本文研究了这些数据分发技术在ITS环境中的适用性。

A variety of general-purpose data distribution technologies have emerged within the Information and Communications Technologies (ICT) industry. These technologies generally provide services at the Open System Interconnect (OSI) session, presentation and application layers (i.e. layers 5-7). Within Intelligent Transport Systems (ITS), these layers roughly correspond to the facilities layer of the ITS station (ITS-S) reference architecture, as defined within ISO 21217. This document investigates the applicability of these data distribution technologies within the ITS environment.
