Application Research Of QoS In Multi-Service IP Bearer Nwetworks

Currently, the building of a unified multi-service IP bearer network, instead of previousvariety of services and telecommunications network systems, in order to achieve a unified bearing,unified operation, unified management, unified maintenance, to reduce operating costs and improvebusiness flexibility and deployment profitability has become the consensus of operators.For such aunified multi-service IP bearer network, QoS (Quality of Service) is a very important basicrequirements. Zaozhuang Unicom has built up a multi-service IP bearer network (carrying voice,data services and the upcoming opening of the IPTV video services).NGN business has a lot of useit. We found that if NGN services and Internet services use the common network equipment, infact, network quality is not stable, the specific phenomenon is: the average performance is better,transient poor, voice quality is poor.The paper by Zaozhuang Unicom IP bearer network of multi-service analysis of the problems,explore the data for IP devices to conduct a detailed study, after many trials and operational testing,softswitch bearer network from the impact of several important index:jitter, latency, packet loss rate,bandwidth issues specific analysis, research, analysis of Internet traffic on the impact of NGNservices solve the persistent problem of instability of voice calls, set up a high quality to guaranteeQoS multi-service IP bearer network,improve network quality and safety, maximize utilization ofnetwork resources.Zaozhuang Unicom built by multi-service IP bearer network in network operation proves thatthe current IP bearer network have the ability to meet the latency, jitter and bit error raterequirements. According to business development, step by step deployment of QoS, improvebusiness service quality and user perceptions, support more broadband differentiated products tomeet the user's speed, stability, reliability, availability, diversity, flexibility and other qualityrequirements, better and better promote the development of broadband services.
