摘要
目前VPN技术在各类网络中的应用大量存在,随着网络技术的发展,IP网络中不仅单独承载普通数据业务,3G语音、视频、数据等业务融合承载,综合应用,对网络的承载能力有了更高的要求。而各类业务在VPN中的大量应用,对于使用VPN对各类业务承载的时延、抖动、丢包率等提出更严格的要求。本文试对目前应用最广泛的MPLS/BGP VPN业务中的DiffServ模型的QoS的典型应用场景进行阐述,探讨对VPN业务的QoS保障。
Currently VPN technology is used in all kinds of networks. But with the development of network technology, IP network bears not only single common data, but also 3G voice, video and data, etc. So the comprehensive application is in high demand. Considering all kinds of business in the application, VPN carrying delay, jitter, packet loss rate offers more strict re quirements. This paper tries to discuss the typical application of QoS scene of DiffServ model in most widely used MPLS/BGP VPN business, VPN with QoS guarantee was also studied.
