实时多媒体网络系统QoS解决方案的研究

Differentiated Service Solution for Real - time Multimedia Network

文章主要通过对实时多媒体网络系统中服务质量QoS进行研究,着重分析区分服务(Diff-Serv)模型实现实时多媒体网络系统中服务质量QoS的具体措施和方法.从目前的网络技术的发展趋势来看,区分服务(Diff-Serv)模型是实现对实时多媒体网络系统中服务质量QoS的唯一可取的技术.它的主要优势在于简化网络服务质量QoS保证的复杂性,加快转发速度,而且区分服务(Differentiated Service)模型具灵活性,可扩展性和简单易于实现的特点.通过区分服务(DiffServ)与多协议标记系统(MPLS)的结合,实现实时多媒体网络系统中服务质量QoS是一个发展方向.

This paper discusses tools for implementation of QoS(Quality of Service) for real - time multimedia network. It also gives the analysis of key technologies of Differentiated Service (Diff - Serv) for QoS. Then the detail approaches and steps of Differentiated Service are proposed to provide the QoS for real - time multimedia network. The combination of Differentiated Service and MPLS is a potential solution to QoS for real - time multimedia network.
