电信级以太网技术讲座 第3讲 以太网线性保护与环网保护

Ethernet Linear Protection and Ring Protection

高可靠性是以太网技术达到电信级要求的主要挑战之一。列举了与可靠性相关的以太网技术,分析了保护的时间模型和目标,重点基于ITU-T标准介绍了以太网线性保护和环网保护方面的最新发展,并对其相关标准、协议机制和实现与应用等进行了阐述和分析。

High reliability is one of the key challenges for Ethernet technologies to meet the carrier-class requirements. This paper presents the related Ethernet technologies to reliability and introduces the temporal model and requirements of protection in the carrier Ethernet. Based on the development of Ethernet OAM standards and technologies, this paper analyzes the corresponding protocols, mechanisms, implementations and applications.
