Consider a two-link network where Host A is connected to the router by a 1 Mbps link with 10 ms propagation delay and the router is connected to Host B by a 15 Mbps link with a 25 ms propagation delay.
Host A sends a 1500-byte packet to Host B.
What is the transmission delay (in ms) of the packet from Host A to the router?
Homework Answers
Observe: transmission delay between A and router is asked only!
a 1500 byte packet:
- over a 1Mbps link gets a transmission time = (1500 x 8)/(1 x 220) = 11.44 ms (approx)
- a propagation delay = 10 ms
Hence the total transmission delay = 11.44 + 10 = 21.44 ms (approx)

3. Consider sending real-time data from Host A to Host B over a packet-switched network. Host A takes a 32-bit measurement every millisecond, and Host A collects these into 128-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps, its propagation delay is 2 × 108 meters/sec, and its length is 1500 km. As soon as Host A gathers a packet, it sends the packet to Host B. How much time elapses from...

3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...

QUESTION 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)?"...

Tig. 1 2. Consider the scenario shown below where (from the bottom up), you notice three hosts and a local logging server (that stores information that is sent to it) are connected to a router and to each other by a 100 Mbps link, with a near-zero ms propagation delay. That router in turn is connected to another router over a 30 Mbps link with a 50 ms propagation delay, and that latter router is connected to two remote logging...

Host A is connected to Host B through a 100 Mbps link which has a propagation speed of 3 * 108 m/s, and the two hosts are 30 km apart. Assuming the network is not busy so that there are no processing or queueing delays, what is the end-to-end delay to send a 100 bit packet from Host A to Host B? (NOTE: Express your answer in milliseconds, i.e. msec and please show work.
