1) How long does it take a packet of length 1,000 bytes to propagate over a link of distance 5,000 km, propagation speed of 2.5 x 108 m/s, transmission rate 1 Mbps? Generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on transmission rate? 2) suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 2 Mbps. Suppose the propagation speed over the link is 2.5 x 108 meters/sec. a. Calculate the bandwidth-delay product, R x dprop.b. Consider sending a file of 800, 000 bits from Host A to Host B. Suppose the file is sent continuously as one large message. What is the maximum number of bits that will be in the link at any given time?c. Provide an interpretation of the bandwidth-delay product? 3) Consider sending a packet from a source host to a destination host over a fixed route. List the delay components in the end-to-end delay. Which of these delays are constant and which are variable? 4)Protocol layers What are the five protocol layers, from the top to bottom, in the Internet? For each of the five layers, what is the name of the pack0065ts processed at the layer? An end system processes up to which layer? A router processes up to which layer? A link layer switch processes up to which layer?
