全光传送网的生存性技术

The Survivability of Optical Network

互联网和其他通信网络的爆发性成长,导致对更大带宽、更高生存性业务的需求急剧增长。在网络故障的情况下,为了使光通路的数据丢失最小化,我们可以使用不同的保护和恢复方案。好的保护方案可以使网络业务更快地从故障中恢复过来,满足光网络对故障恢复时间的苛刻要求(毫秒级)。本文主要讨论光通路的保护方案。

The explosive growth of the Internet and other network has created tremendous demands for more bandwidth and more survivable services. Protection schemes restore traffic from failure more quickly and satisfy the critical restoration time,which is on the degreed of millisecond of optical network well. In this paper, we mainly study the lightpath protection schemes.
