| 摘 要： | 自动交换光网络(ASON)是当前光传输领域的研究热点，其中保护恢复策略将为增强网络生存性奠定新的基石。本首先介绍了ASON中的保护和恢复机制以及它们各自的特点。并在此基础上讨论它们与传统SDH网络保护恢复机制比较所表现出的几点优势，最后，针对ASON的传送平面和控制平面的保护恢复提出主要的技术要求，这些要求将有助于保证ASON在生存性方面优势的真正实现。

| Abstract: | Presently,ASON is the research hotspot in optical transportation network,in which protection&restoration mechanism can enhance network survivability to a new level.Firstly,the characteristic of protection&restoration in ASON is introduced.Then,based on the former introduction,the advantages of protection&restoration mechanism in ASON over the traditional SDH network are discussed.Finally,the pri- mary technical requirements of protection and restoration in control plane and transport plane of ASON,which can guarantee effective reali- zation of ASON advantages in survivability,are analyzed. |
