The distance from Earth to Mars is about 90 * 106 meters in the best case (the exact distance depends on the relative orbital positions of the two planets and can be much more). Assume there is a link between Earth and Mars with a transmission rate of 2Mb/s. We need to send a packet from Earth to Mars over this link,

Suppose that KJ sends 3596 back-to-back packets, with each packet composed of 14,000 bits, to TA over 5 links (shown below). Suppose that the transmission rate of each link is 70,000 bits/sec (bps). Consider the routers to be store-and-forward routers. In such a scenario, find the endto- end delay of sending all the packets to TA (i.e., the time needed for the last bit of the last packet to arrive at TA since KJ starts transmitting the first bit of the first packet). Note, consider only the transmission delay that occurs in sending packets in your analysis. Show the steps used for derivation in detail. 70,000 bps 70,000 bps 70,000 bps 70,000 bps 70,000 bps KJ Router 1 Router 2 Router 3 Router 4 ТА

Suppose that we are sending a 30 Mb MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 × 108 meters/sec, and the distance between source and destination is 10,000 km. 1. Now suppose there is only one link between source and destination, and there are 10 FDM channels in the link. The MP3 file is sent over one of the channels. What is the end-to-end delay?

200 nodes are connected to a 1,500-meter length of coaxial cable. Using some protocol, each node can transmit 50 frames/second, where the average frame length is 2,000 bits. The transmission rate at each node is 100 Mbps (where 1 Mbps = 1,000,000 bps). What is the efficiency of this protocol?

Consider a packet that consists of 1000 bytes, including any headers. How long does it take to transmit this packet onto a data link if the transmission speed of the link is 8 Mbps (Megabits per second)? а. .000001 second O b. .125 seconds с. .000125 seconds O d. .001 second

Host A and B are directly connected by an 8mps link. The distance between the two host is 4000 kilometers. The propagation speed over the link is 2 x 10^8 m/s, and all packets are 1000 bytes long. What is the propagation delay, in seconds, between the two hots? What is the transmission delay, in seconds, between the two host?

A frame of 1200 bytes travel through five switches along the path. Each link has a bandwidth of 100 Mbps, a length of 100 m, and a propagation speed of 2 × 10*8 m/sec. Assuming a queuing and processing delay of 2 ms at each switch, what is the approximate end-to-end delay for this packet?
