摘　　要：MPLS VPN是当今主流的虚拟专用网技术。在MPLS VPN中传输融合语音、视频和关键数据,其关键是要实现有效的QoS保证。在对DiffServ和MPLS TE进行研究的基础上,引入MPLS DS-TE。DS-TE结合DiffServ的区分服务和MPLS TE的端到端有效路由策略,运用带宽约束模型,在MPLS VPN中实现端到端区分服务的QoS保证。MPLS VPN is the mainstream of present virtual private network technology.In order to transmit the integration of voice,video and critical data in MPLS VPN,the key is to achieve effective QoS guarantee.Based on the study on DiffServ and MPLS TE,it introduced the MPLS DS-TE.By combining the differentiated Services of DiffServ with the effective end-to-end routing strategy of MPLS TE,and employing the bandwidth constraints model,DS-TE achieves QoS guarantee of end-to-end and differentiated Services in MPLS VPN.
