IP/DWDM光Internet中的一种公平智能QoS组播路由机制

QoS（Quality of Service）与组播是IP/DWDM光Internet中应该具备的基本能力.本文研究了IP/DWDM光Internet中的公平智能QoS组播路由机制.在所提出的机制中,QoS需求的区间表示形式体现了对柔性与异构QoS的支持;根据微观经济学理论,建立基于Kelly/PSP模型的定价策略,体现组间公平性;使用下游链路均分方法在组成员之间分摊费用,体现组内公平性;基于点火耦合神经网络,建立智能QoS组播路由算法.以上各方面有机结合,构成IP/DWDM光Internet中的公平智能QoS组播路由机制.仿真结果表明,该机制是可行和有效的.

A Fair and Intelligent QoS Multicast Routing Mechanism in IP/DWDM Optical Internet

QoS (Quality of Service) and multicast are essential capabilities in IP/DWDM optical Internet. In this pa- per, a fair and intelligent QoS multicast routing mechanism in IP/DWDM optical Internet is discussed. In the proposed mechanism, QoS requirement is denoted by an range to support the flexible and heterogeneous QoS, according to the microeconomics theory and method, a Kelly/PSP-model-based pricing strategy is presented to support the inter-group fairness; the ELSD (Equal Link Split Downstream) method is adopted to apportion the cost among group members, thus the intra-group fairness is provided; based on FCNN (Firing Coupled Neural Network) , an intelligent QoS multi- cast routing algorithm is introduced. Combining the above, a fair and intelligent QoS multicast routing mechanism is es- tablished. Simulation results have shown that the proposed mechanism is both effective and efficient.
