基于业务的智能光网络生存性研究

目前对于智能光网络（ION）生存性方面的研究主要是针对光网络本身，基于静态的资源配置和管理机制对于快速变化的业务需求而言缺乏灵活性，难以满足未来智能光网络中复杂业务的需求。基于业务的智能光网络生存性策略，可以解决现有网络生存性策略与业务侧的生存性需求之间的差异。通过将对生存性需求的描述和定义从网络侧转移到业务侧，以业务对生存性的需求为核心，能很好地实现智能光网络中对生存性策略的控制和实现。

Survivability in Service-based Intelligent Optical Networks

Nowadays, the survivability research of Intelligent Optical Network (ION) is mainly about optical network itself. Source allocation and management mechanism based on static features lacks flexibility for fast changing services requirements, and is difficult to satisfy the complex services in the future ION. The survivability strategy of service-based ION can solve the problem of differences between the existing network survivability strategy and the survivability requirements on the service side. By describing and defining the survivability requirements on the service side in stead of the network side, and aiming at service survivability, the survivability strategy of ION can be well controlled and implemented.
