U = set-up time for circuit switch (seconds) Y = transmission delay per link (seconds) (also called “transfer delay”) L = message length (bits) >0 R = transmission rate (bits per second) >0 (also called “placement rate”) H = header size (bits) =>0 P = packet size (bits) >H (note that this is the total packet size, i.e. header + data) X = decision time per packet (also called “packet routing delay”) 1. If L=1000, Y=1, R=4000 and U=1, choose a value of X. What is the total transmission time in the circuit switch network and packet switched network? Consider P=125 and H=25. (3 marks)

What are contention periods in CSMA? Why are they used?
As far I know that, contention slots are required to avoid all channels from transmitting at the same time. But what happens when the contention slot is over? All stations will transmit together and it will lead to jamming of the channel then. What exactly is the role of contention slots and how does it avoid collisions?

Since 8 bit delimeter pattern = 01111110. So whenever 0111111( 6’s ones) is matched we will add one extra bit. But in the solution extra bit is added just after 011111(5’s ones).
