时间敏感网络关键技术与应用研究

Research and Application of Time-Sensitive Networking Key Technique

时间敏感网络(TSN)是计算机网络领域的一个新兴研究方向。在TSN提出之前,各种类型的实时以太网已经作为若干低速率总线的替代,被引入到工业控制领域。但它们在标准以太网如何支持实时性问题上,选择了不同产品相互之间无法兼容的增强途径。为此,IEEE TSN工作组推出一系列开放标准协议,在源头上解决各厂商技术产品间的互联互通问题,并确保TSN与标准以太网兼容,为打通信息技术世界和操控技术世界提供了便利。介绍TSN关键技术、分析典型应用场景。

Time-Sensitive Networking(TSN) is a new research direction in the field of computer network.Prior to TSN,various types of real-time Ethernet is introduced into industrial control as an alternative to several low-rate buses.But they choose different ways that are not compatible with each other in how standard Ethernet supports real-time.To this end,the IEEE TSN Working Group has launched a series of open standard protocols to address connectivity between technology products from different vendors at the source and to ensure compatibility between TSN and standard Ethernet,facilitating access to the information technology world and the operational technology world.This paper introduces TSN technology,analyzes and ponders its application prospects,especially in naval scenes.
