Find the total sum of transmission and propagation delays in transmitting the file using sliding window concept.
Consider a source computer (S) transmitting a file of size 106106 bits to a destination computer (D) over a network of two routers (R1 and R2) and three links (L1,L2, and L3). L1 connects S to R1; L2connects 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 1 Mbps. 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
