What if the range allocation of the binary exponential backoff is different?

Asked by dangdangchik0415 (2points) 1 week ago

The binary exponential backoff is a kind of countdown that starts after the NIC stops transmission and selects a random value of 0–2^n-1. The maximum value of n is 15.
a) What happens if the maximum value of n is set a little lower than 15 (3 or 4)?
b) What happens if the maximum value of n is set higher than 15 (1000 or 2000)?
c) If the range of random values is set to 0~n, which is a form of increasing by 1 rather than 0~2^n-1, what are the advantages and disadvantages?

You need to look at this algebraically.

IN your step 1, use Lim(n) where n=max(3*4)squared divided by 15.

Same general idea with Step 2.

Step 3 is more difficuly; you need to use factorials – 15! as the seed of your random values for production, and then take those numbers

ran(15!) +n squared + lim(2000) to get the right number.

The rest is up to you.
