摘要：In recent years, IP over WDM has become a key technology of choice for meeting the tremendous bandwidth demand in the optical infrastructure. Survivability is an emerging discipline that blends optical network security with business risk management for the purpose of protecting highly distributed information services and assets. No system is totally immune to attacks, accidents, or failures. Therefore, the focus of this new discipline is not only to that suddenly accident, but also to ensure that mission-critical functions are sustained and a essential set of services is delivered, despite the presence of accident. Improving survivability is very important for optical network.
