MPLS Fundamental History of WAN Protocol 1970年代之前 第一个 WAN 用于将办公室与终端连接到大型机和小型计算机系统. 它是从办公室到数据中心的点对点连接. 随着用户采用个人计算机和客户端服务器应用程序,点对点架构继续为行业服务. 当时使用的X.25 协议和 T1/E1 电路速率为1.5Mbps. 1980 年代末和 1990 年代初 帧中继(X.25 的简化版本)作为一种更灵活的方式出现,可将办公室和分支机构位置连接到数据中心,通过 T1/T3 电…

1.1  MPLS简介 MPLS(Multiprotocol Label Switching,多协议标签交换)是一种新兴的IP骨干网技术.MPLS在无连接的IP网络上引入面向连接的标签交换概念,将第三层路由技术和第二层交换技术相结合,充分发挥了IP路由的灵活性和二层交换的简捷性. MPLS广泛应用于大规模网络中,它具有以下优点: 在MPLS网络中,设备根据短而定长的标签转发报文,省去了通过软件查找IP路由的繁琐过程,为数据在骨干网络中的传输提供了一种高速高效的方式. MPLS位于链路层和网络层之…

QoS控制原理 · 基于设备的QoS保障技术——CAC· 基于优先级设置的QoS保障技术· 基于减小抖动的QoS保障-Jitter BufferIP传输在时延.抖动.丢包率方面的性能不及TDM传输,而这些性能恰与语音质量息息相关,过大的时延.抖动或丢包率将直接影响通话质量,甚至会造成掉话.因此,QoS(Quality of Service,业务质量)控制对于VoIP来说非常重要.QoS包括了传输的单向时延.丢包率和抖动三个方面.引起网络质量QoS下降的最大问题在于:· IP承载网存在网络损伤(如…
