| 摘 要： | 近年来,基于区分生存性业务(DRS)的多层生存性问题在智能光网络生存性技术的研究中愈发受到关注.本文在分析现有多层生存性机制存在问题的基础上,结合DRS模型,设计了一种基于DRS的多层生存性策略,并对层间协调机制中的关键问题进行了研究.该策略不仅考虑了业务的可靠性需求差异,而且平衡了网络资源分配,有重要的实际应用价值.

| Abstract: | Multi-layer survivability scheme of intelligent optical network based on DRS are more and more concerned nowadays. Firstly,this paper discusses some problems,which occur in traditional multi-layer survivability scheme. Based on this,the paper proposes a new multi-layer survivability scheme based on DRS,and the key issues of coordination mechanisms between layers have been studied. This scheme not only consider the distinctions of differentiated resilience services,but also balance the network resource alloc... |
