[CCNP-ROUTE]Question 100
本帖最后由 陳罐西 于 2017-7-24 14:59 编辑If the total bandwidth is 64 kbps and the RTT is 3 seconds, what is the bandwidth delay product?
怎么通过带宽和RTT 算出延迟的
Bandwidth Delay Product = bandwidth (bits per sec) * round trip time (in seconds) / 8 = 24000

噢原来是这样。
可是我看了一下,这个公式的计算单位
64Kpbs=64KBytes/sec
64(KBytes/sec)*3(sec)=194KByte
194/8=24Kbit
为啥答案给的全是Kbyte Thank you
