We are sending a MP3 file of 1,000,000 bits from a source host to a destination host. All links in the path between source and destination have a bandwidth of 10 Mbps. Assume that the propagation speed is 2.5 * 10 8 meters/sec, and the distance between source and destination is 10,000 km.
1. Now suppose there are two links between source and destination, with one switch connecting the two links. Each link is 5,000 km long. Again suppose the MP3 file is sent as one message. Suppose there is no congestion, so that the message is transmitted onto the second link as soon as the router receives the entire message. What is the total transfer time?
2. Now suppose that the MP3 file is broken into 5 packets, each of 200,000 bits. Ignore headers that may be added to these packets. Also ignore switch processing delays. Assuming store and forward packet switching at the switch, what is the total transfer time?

We are sending a MP3 file of 300,000 bits from Host A to Host B.
Host A and B are each connected to a switch S via 100 Mbps links.
Assume that each link introduces a propagation delay of 10 µs
(microsecond). Calculate the total transfer time of the entire file
(from first bit sent to last bit received) for the following:
Suppose the MP3 file is sent as one message. S is a
store-and-forward device; it begins retransmitting immediately...

Consider sending a large file of F bits from Host A to Host B.
There are three links (and two switches) between A and B, and the
links are uncongested (that is, no queuing delays). Host A segments
the file into segments of S bits each and adds 80 bits of header to
each segment, forming packets of L=80+
S bits. Each link has a transmission rate of R bps. Find the value
of S that minimizes the delay of...

Suppose Host A wants to send a large file to Host B. The path
from Host A to Host B has three links, of rates R1 = 200 kbps, R2 =
2 Mbps, and R3 = 1 Mbps. Assuming no other traffic in the network,
what is the average throughput for the file transfer? Suppose the
file is 4 million bytes, on average, how long will it take to
transfer the file to Host B? Repeat (a) and (b), but...

1. A file of size 500 MB is to be transferred from host H1 to
host H2 through routers R1, R2 and
R3. See Figure 1 below.
h1=2mbs=>R1==8mbs=>R2==10mbs==>R3=1mbs==>h2
(a) If the file is transmitted is one entity, without dividing it
into smaller chunks, estimate
how long it would take for the file to arrive at the receiver. [4

(b) If the file is first divided into smaller chunks, and each
chunk is transmitted and then
combined, estimate how long...

How long does it take to send a 15 MiB file from Host A to Host
B over a circuit-switched network, assuming:
- Total link transmission rate = 49.7 Gbps.
- Network is FDM, with 7 permitted users, each with an equal
bandwidth share.
- A link connection requires a setup time of 84.5 ms.
Your answer should be in miliseconds (ms) with one decimal place,
and without the unit (e.g. "140.6" without the quotes)

to the destination country, which of the following statements
describe the effect of the immigration on the destination country
in the long run? Select one or more: a. In the destination country,

country, no change in the price of either the labor-intensive or
capital-intensive good. c. In the...
