Q: Consider two nodes, A and B, connected by a medium with link rate D bps. The distance between these nodes is n meters. The Propagation speed of the link is represented by t meters/sec. Node A has sent a packet of T bits to node B. a. Consider t = T = 520 bits, and D = 73 Mbps. What is the distance n which makes dp + dt 5.3 x 108 , %| b. Find end-end delay of the network if dq=2.3msec, dproc=4msec. c. Consider a router R exists between A and B, the link rate DA-R=52 kbps and DR-B=774 kbps. Find hop-hop delay of all hops. d. Consider dp is more than dt, where will be the first bit of the message at time t = dt and then now consider dp is smaller than dt. When time is dt, where will be the first bit?

**Question:** Consider two nodes, A and B, connected by a medium with link rate \( D \) bps. The distance between these nodes is \( n \) meters. The propagation speed of the link is represented by \( t \) meters/sec. Node A has sent a packet of \( T \) bits to node B. a. Consider \( t = 5.3 \times 10^8 \) m/s, \( T = 520 \) bits, and \( D = 73 \) Mbps. What is the distance \( n \) which makes \( dp + dt \)? b. Find end-to-end delay of the network if \( dq = 2.3 \) msec, \( d_{proc} = 4 \) msec. c. Consider a router \( R \) exists between A and B, the link rate \( DA-R = 52 \) kbps and \( DR-B = 774 \) kbps. Find hop-hop delay of all hops. d. Consider \( dp \) is more than \( dt \), where will be the first bit of the message at time \( t = dt \) and then now consider \( dp \) is smaller than \( dt \). When time is \( dt \), where will be the first bit?
