摘　　要：针对专用IP网络规模不断扩大、承载业务日趋多样化、数据包大小差异大,以及不同类别和重要度的数据在同一网络平台上无差别传输,造成数据相互干扰和传输可靠性无法保证的问题,结合专用IP网络体系架构的特点,比较了典型的服务质量(QoS)服务模型。采用区分服务思想优化了QoS策略,设计了全网统一的QoS部署模型,给出了不同应用场景的配置方案,并对整形线速应用进行了重点分析,为其他网络QoS部署方法提供了参考和借鉴。As the scale of private IP network is extended,such phenomena are occurred,including diversification of carrying services,large difference in packet size and mutual interference of data and unguaranteed transmission reliability caused by non-differential transmission of data with different types and importance on the same network platform.In view of these problems,compared with the typical Quality of Service(QoS)models and based on the characteristics of private IP network architecture,the QoS strategy is optimized by using differential service idea,and a unified QoS deployment model in whole network is designed.The configuration schemes are proposed for different application scenarios.The application of shaping and line-rate is analyzed in detail.The research can provide reference for QoS deployment methods of other networks.
