一、概念辨析:网络延迟与网络波动(1)网络延迟网络延迟是指各式各样的数据在网络介质中通过网络协议(如TCP/IP)进行传输,如果信息量过大不加以限制,超额的网络流量就会导致设备反应缓慢,造成网络延迟。受限于光速,网络延迟总是有一个下限,是无法超越物理极限的。(2)网络波动(丢包率)网络波动,就是Flipping,一般在广域网才会提到,是由于线路的不稳定,出现时通时断或瞬断的现象。Flipping是会经常出现、不可避免的,这就需要路由协议对这种现象较好地处理,网络设计和调试人员,在设计和设备配置时,也可以采用多种技术,避免这种现象出现,提高网络的容错能力。二、加速方案当前网络加速实现方案和加速产
