Unacademy AIMT - 1
In a shared Ethernet link, each user is active only 10% of the time. Suppose switching is used for 10 users and each user is equally likely to transmit at any point of time. The probability P that at any given time exactly 8 users are transmitting simultaneously. What is the value of $10^{10} * P$? Solve for both: 1)Packet switching. 2)Circuit switching.

How long does it take a packet of length L to propagate over a link of distance D, propagation speed S, and transmission rate R bps. Does this delay depend on transmission rate? Answer given is No. But I don't understand how it is possible. Until the packet is transmitted , it can't be propagate over the link.
