摘　　要：对IP/WDM网络的集成服务质量(QoS)控制技术问题做了研究,给出了基于通用多协议标记交换(GMPLS)技术的业务差分处理模型,设计了新的业务分类、光路分类以及层间映射 /疏导 /重构策略,给出了具体的映射技术方案 本方法具有三大特点: 1)光电集成的差分服务模型;2)多粒度多优先级业务的自适应资源管理机制; 3)支持电信级应用 该模型较好地折中了多种类型业务的QoS控制复杂性和有效性,具有较强的实用性和可扩展性,能够解决光因特网络中支持多媒体业务传送的QoS问题.A new scheme with the integration of optical and electrical QoS control for the next generation IP/WDM networks is developed. Integrating differentiated model based on generalized multi protocol label switching (GMPLS) technologies is proposed, and new service classification strategies and service mapping strategies are also provided. The proposed QoS control methods in this paper have the unique features of optical electrical integrating differentiated service model, intelligent control for multi granularities multi priorities applications, and the compliance to meet carrier class service level agreement, which capture the better tradeoff between the finer QoS granularity of IP layer and the coarse QoS granularity of optical layer to support multiple levels of service performance. Furthermore, the proposed scheme provides much lower complexity, better robustness and scalability, which seems to be preferred for QoS provisioning in the future multi service IP/WDM networks.
