Question

QUESTION 1

1. "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second that can be transmitted by the link (use a whole number)?"

QUESTION 2

1. "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 4000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the transmission delay (the time needed to transmit all of a packet's bits into the link) (in seconds)?"

QUESTION 5

1. "Host A is sending a file to Host B. There are 3 links (therefore 2 switches) between the hosts. The file is segmented into packets of 40 bytes, with a 10 byte header added to each packet. Each link has a transmission rate of 100 kbps and a speed of 1000 km per sec. The switches are 100km away from each other. Host A is 50 km away from the first switch while Host B is 150 km away from the second switch. Data travels from Host A to the first switch, on to the second switch and then to Host B. What is the propagation delay (in seconds) when a packet of data travels from Host A to the first router?"
