摘　　要：SDH网的自愈机制是SDH网生存性研究的主要内容，也是确保SDH网正常运行的关键。本文在分析了传统的SDH自愈环的基础上，提出了一种新的双向四纤智能通道保护型自愈环（BSHR／4IP）自愈机制，并通过计算机模拟，对其性能进行了分析。SDH self-healing mechanism is an important aspect in SDH survivability research, and also the key factor for ensuring SDH network operation-smoothly. The paper based on analysis of various traditional SDH self-healing rings proposes a new bidirectional four-fiber intelligent path protection self-healing ring. The performance is evaluated and compared-via simulations.
