P6. This elementary problem begins to explore propagation delay and transmis- sion delay, two central concepts in data networking. Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B a. Express the propagation delay, dprops in terms of m and...

A and B which are separated by 920 Km are directly connected using some type of physical link. A is sending packets to B with a packet size of 8000 bits at a bit rate of 2 Mbps. If the first bit transmitted by A has just reached B when the last bit is being transmitted by A, calculate the velocity of propagation in the medium in two different ways: (i) Using the concept of delay-bandwidth product (ii) Using the...

Hosts A and B communicate through a store-and-forward switch. The links between the hosts and the switch have a transmission rate of R bits/sec. What is the total delay for sending a packet of L bits from host A to host B (i.e., from the time A starts transmitting to the time B has the packet).

Hosts A and B are each connected to a switch S via 1-Gbps links as below. The propagation delay on each link is 20 μs. S is a store-and-forward device; it begins retransmitting a received packet 35μs after it has finished receiving it. Calculate the total time required to transmit 10,000 bits from A to B in the following two cases: When all the 10,000 bits are transmitted in a single packet? When the 10,000 bits are transmitted in two...

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...
