If the total bandwidth is 64 kbps and the RTT is 3 seconds, what is the bandwidth delay product?
正解:C
Explanation/Reference: Explanation: Bandwidth delay product is defined as capacity of a pipe = bandwidth (bits/ sec) * RTT (s) where capacity is specific to TCP and is a bi-product of how the protocol itself operates. 64 kbps = 64.000bps 1byte=8bit 64.000/8=8.000*3=24.000 Reference: https://supportforums.cisco.com/t5/wan-routing-and-switching/tcp-performance-bandwidth-delay-product/ td-p/765376
