GO Classes 2023 | IIITH Mock Test 3 | Question: 43
$A$ and $B$ are the only two stations on an Ethernet. Each has a steady queue of frames to send. $A$ and $B$ attempt to transmit a frame, collide, and $B$ wins the first backoff race. At the end of this successful transmission by $B$, both ... transmit and collide. The probability that $A$ wins the second backoff race is: $5/8$ $1/16$ $1/8$ $3/16$

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.

Andrew S. Tanenbaum Edition 5th Exercise 4 Question 43 (Page No. 353)
Write a program to simulate the behavior of the CSMA/CD protocol over Ethernet when there are N stations ready to transmit while a frame is being transmitted. Your program should report the times when each station ... detection and sending of a jamming sequence takes one slot time. All frames are the maximum length allowed.

Andrew S. Tanenbaum Edition 5th Exercise 4 Question 18 (Page No. 352)
Ethernet frames must be at least 64 bytes long to ensure that the transmitter is still going in the event of a collision at the far end of the cable. Fast Ethernet has the same 64-byte minimum frame size but can get the bits out ten times faster. How is it possible to maintain the same minimum frame size?

Andrew S. Tanenbaum Edition 5 Exercise 4 Question 16 (Page No. 352)
Two CSMA/CD stations are each trying to transmit long (multiframe) files. After each frame is sent, they contend for the channel, using the binary exponential backoff algorithm. What is the probability that the contention ends on round k, and what is the mean number of rounds per contention period?
