在本文中，我们讨论了一个定量的框架，尽最大努力保护的光学层。该框架提供了一种方法来桥接完全保护连接与不受保护保护连接的两个已知保护等级之间的差距。该框架允许指定连接将被保护的概率，以可能不同的价格为客户提供全方位的保护保证。由于连接可以被部分地保护，因此可以减少所需的保护带宽。保护带宽的数量取决于一个'等效的生存带宽。该框架还扩展到可抢占（低优先级）连接和不同的环架构。
In this paper we discuss a quantitative framework for best- effort protection of the optical layer. This framework provides a way to bridge the gap between two known protection grades of fully protected connections vis-a-vis unprotected protection. The framework allows to specify the probability with which the connection will be protected, providing the customer with a full range of protection guarantees at possibly different prices. Since connections may be partially protected, the required protection bandwidth can be reduced. The amount of protection bandwidth is shown to depend on an 'equivalent survivable bandwidth.' The framework also extends to preemptable (low priority) connections and to different ring architectures.
