Question

Suppose the MAC layer frame is up to 500 bytes. Each header or trailer is 60 bytes:
a) What is the overhead?
b) Consider a message of 1 M byte. Suppose the frame drop probability is p=0.1. How many bytes have to be transported to deliver the 1 M bytes user message, considering only one hop?
c) If not limiting frame size, what is the optimal frame size?

Answer 1
