Consider a source computer(S) transmitting
a file of size 106 bits to a destination computer
(D)over a network of two routers (R1 and R2)
and three links(L1, L2, and L3). L1connects S
to R1; L2 connects R1 to R2; and L3 connects
R2 to D. Let each link be of length 100 km.
Assume signals travel over each link at a speed
of 108 meters per second. Assume that the link
bandwidth on each link is 1Mbps. Let the file
be broken down into 1000 packets each of size
1000 bits. Find the total sum of transmission
and propagation delays in transmitting the file
from S to D?
a. 1005 ms
b. 1010 ms
c. 3000 ms
d. 3003 ms
