摘要
SDH(Synchronous Digital Hierarchy,同步数字体系)环网作为底层传输骨干网,因其高带宽、高稳定性及完善的网络管理功能,已经越来越广泛地被应用于生产生活的方方面面。但SDH的蓬勃发展同样带来了维护上的瓶颈,针对SDH运维中容易被忽视的时钟跟随问题进行展开并设定一个极端环境,论述SDH环网"时钟风暴"的产生及其原因,进而提出一种合理的解决方案,以供基层运维人员参考。
As backbone network for bottem transferring, Synchronous Digital Hierarchy （SDH） ring network has been applied wider and wider in all sides of production and life for its high band-width, high stability and perfect managing function. An extreme situation is set against the problem of clock following during running of SDH which is easily being ignored. The producing of clock storm of SDH ring and its reasons are analyzed, and a reasonable solution are put forward, which offeres a reference for relative persons.
