MPLS中的实时视频传输技术探讨

Discussion about real-time video transmission based on MPLS

从实时数据传输的网络参数及传输时对网络的要求出发,分析了在基于Internet的实时视频传输所存在的问题。参照MPLS的技术优势,对比传统IP技术的不足,提出了在MPLS中解决实时视频传输的时延等问题的技术方案。通过介绍Diff-serv over MPLS的传输机制,从理论上阐明了MPLS技术支持QoS保障所具有的优势。

This article explains the network parameters and the demands which the IP network must meet in the transmission of the real-time video data. The problems which exists in the real-time video transmission on Internet are analyzed. Comparing with the classical IP and taking the advantages of MPLS, this article brings forward a new method to resolve the delay in the real-time video transmission. Through introducing the mechanism of Diff-serv over MPLS, the article describes the advantages of using MPLS to improve the service quality.
