希望计算机网络高手帮我解答一下这个问题~ the bandwidth of the channel with 4 routers between host A and host B in different situation.the propagation delay of each link is about 10us
1,circit switching the set up need 10ms
2,message switching
3,packet switching
3. packet switching: each packet size is 5KB

题目没抄完整吧...
The bandwidth of the channel with 4 routers between host A and B is 1Mbps, Consider how long does a 5 MB message transmit from A to B in different situation, the propagation delay of each link is about 10 us, (1) Circuit switching: the setup need 10 ms; (2)Message switching; (3)Packet switching：each packet size is 5KB.
此次与4个主机A和B之间的路由器，信道带宽是1Mbps，考虑多久一个5 MB的邮件发送从A到B在不同的情况，各个环节的传播延迟约为10,我们，（1）电路交换：安装需要10毫秒，（2）信息交换;（3）分组交换：每包大小为5kb的。 是这样的吧.
1M的带宽理论上只能达到100k/s，但有时候也会超出，也会低，这有一个差值，不能下结论的。
