IP流量规划与区分服务结合是增强网络服务质量保证的新方法.在分析区分服务对流量规划需求的基础上,设计了区分服务与流量规划结合的功能框架,提出了适合流量规划要求的队列调度方法和流量分割与映射的原理与方法.流分割方法基于表对数据流进行分割.该方法既能体现区分服务数据包的转发优先级的差异,又能保证数据流的延迟与同步要求.
The combination of IP traffic planning and differentiated services is a new way to enhance network service quality assurance.On the basis of analyzing the demand of differentiating services to traffic planning, a functional framework of differentiated services and traffic planning is designed and a queue scheduling suitable for traffic planning is proposed Method and principle and method of traffic segmentation and mapping.Flow segmentation method is based on the table to segment the data stream.This method not only reflects the difference of forwarding priorities of service data packets but also guarantees the data stream delay and synchronization requirements.
