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 the time that Host A begins to take the first measurement in a packet until the packet reaches Host B?
Homework Answers
In given information, it must be propagation speed instead of propagation delay because units given are of propagation speed and propagation delay is measured in seconds.
Thank you.

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...

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?

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...

What
happens to the time when the message is segmented?
Network delay and throughput 4. [20 pts.] In a packet-switched network, the source host segments a long message into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. The figure below illustrates the end-to-end transport of a message: (a) without message segmentation, and (b) with message segmentation. Assume the following: message size is M 8 × 106 bits, transmission...

networking question
Consider transmitting a packet from host A to host B via a
router, as shown below:
Suppose that before sending the packet, all the ARP tables (in
the two hosts and in the router) are empty. Assuming
host A knows the IP address of host B, describe all the packets
exchanged before sending the packet to B.

Consider sending a large file of F bits from Host A to Host B. There are m links (and m-1 switches) between A and B, and the links are uncongested (that is, no queueing delays). Host A segments the file into segments of S bits each and adds H bits of header to each segment, forming packets of L = H + S bits. Each link has a transmission rate of R bps. Find the value of S that minimizes...

Consider a packet switching network. Packets from origin host travel over H hops to reach the destination host. Supppose that the origin host wants to transmit a message that is M bits long. The bit rate of all links is C (bits/sec), and the propoagation delay over every link is D seconds. The message will be broken into packets. Suppose that each packet has a constant overhead of V bits. Let L be the fixed payload of each packet. Thus,...
