Serialization delay is a function of how long it will take to get X
bits onto the wire at speed Y

And is simply X/Y

So, a 1500-byte ping will take 214ms to be put on the wire at a line
speed of 560000 bps

(1500*8)/56000 = .214

So, you list the speed of the circuit.... 768000

The fragment size ... 960

So, (960*8)/768000 = 10 ms

So, 384k would equal 5ms
