有线网络流量QoS策略研究

Research of Cable Network Traffic QoS Policy

有线电视业务具有鲜明的混合流量特征,业务向高清化和多元化发展,对网络带宽、延时、抖动等指标提出了新的要求,本文结合控制层流量和业务层流量分析了有线网络流量模型,其中,公共客户业务包括视频类、宽带上网类和增值类,集团客户业务包括视频类和数据类。基于该模型对各类流量的QoS需求进行分析,提出了流量QoS策略,为有线网络运营商业务运营提供建议。

Cable TV services have distinctive characteristics of mixed traffic,and are developing towards high-definition and diversification.This paper puts forward new requirements for network bandwidth,delay,jitter and other indicators.It analyzes the traffic model including control layer and service layer.Public customer services include video,broadband Internet access and value-added.The group's customer services include video and data.Then it analyzes the QoS requirements of various types of traffic and proposes a traffic QoS policy to provide services for cable network operators.
