支持区分服务的全光网络设计和实现

随着光层业务对传送服务质量的要求趋于多样化以及全光网络的智能化演进，光服务等级协定被提出。为了适应各种业务的不同传送需求，未来的光网络碰具有支持区分服务的能力。在多业务环境下。处理好满足业务的不同服务需求和优化网络资源之同的矛盾。需要传送网络流量工程各个功能子模块具有集成多种实现机制的能力，从而在光层实现区分服务的集成化。目前，支持区分服务的光网络流星工程方案还只是研究领域的成果，需要对现有控制平面的协议进行扩展和标准化，从而使光服务等级协定走向实用。

Design and Implementation of All Optical Networks Supporting Differentiated Services

With the diversified QoS requirements of optical layer services and the evolution of all-optical networks towards intelligentization, optical Service Level Agreement (SLA) was introduced. In order to meet different transport requirements for services, the optical network in the future should be able to support the differentiated services. In a multi-service environment, in order to meet different service requirements and at the same time have network resources well optimized, each functional sub-module for flow engineering in a transport network should support multiple implementation mechanisms, thus enabling the integration of differentiated services in the optical layer. However, the optical network flow engineering mechanism supporting differentiated services is just a research result now, and the practical application of optical SLA requires extension and standardization of existing control plane protocols.
