请教几个关于PTN传送网的问题:
请问: 现阶段传送网主要是SDH+WDM的方式,由于是刚性管道,所以对于突发的大容量IP业务承载能力不足,PTN可以有效缓解这一情况。那么请问,什么是所谓刚性管道呢,PTN如果不是刚性管道,能够满足实时的语音业务传递的高质量需求么,再或者对于线路侧带宽同是10G的SDH网络和PTN网络来说,仅仅是内核的不同,能否决定突发IP业务的传送质量呢,这种传送效率的提高是体现在传送时间上的提高还是什么别的方面的提高呢,和可否用个形象点的例子来说明一下SDH的刚性管道和PTN的非刚性管道下传递大量突发IP业务过程中的区别呢,谢谢高手的解答。
恩。。。我也来说两句吧,,怎么理解这个刚性和柔性的区别
