Question

Suppose the round-trip propagation delay for Ethernet is $46.4 \mu s$. This yields a minimum packet size of $512$ bits ($464$ bits corresponding to propagation delay $+48$ bits of jam signal).

(b) What are the drawbacks to so large a minimum packet size?

Answer 1

The drawback of the packet size being large is that it is considerably larger than many high-level packet sizes which will result in considerate amount of bandwidth being wasted. It also imposes an overhead on small packets
