For TCP packets, in the addition to the total byte sum, calculate the overhead ratio as the sum of all headers (including TCP, IP, and Ethernet) divided by the total size of the data that is transferred by the flow. If the flow did not transfer any data (e.g., the connection did not stablish successfully), use the number 9999 instead to represent infinity. Now draw the

CDF of hit ratio. What can you say about TCP overhead base on this chart?

This part of the flow question mentions calculating the overhead ratio but then asks to draw the CDF of the “hit ratio”? I assume this should have said “draw the CDF of **the** ratio”? If not, what is hit ratio?

Thanks
