摘　　要：随着同步数字体系(SDH)多业务平台的日趋发展,传统的SDH保护方式已无法满足现在的需要。提出了一种混合保护方式,在同一个环内实现子网连接保护和两纤双向复用段保护,可实现对高阶和低阶业务的同时兼顾,解决SDH多业务平台的保护问题。该方法在实践中取得了良好的效果。With the rapid development of Synchronous Digital Hierarchy （SDH） multiple operation platforms, traditional optical network protection is not enough for the newly arising needs. A mixing protection method is presented. It fuses SNCP and MS-SPRING, actualizing the two protection techniques within the same ring of optical network. Experiments show that the method, which is compatible for not only high-path but also low-path business, can solve the problem of SDH multiple operation platforms.
