1. In modern
packet- switched networks, including the Internet, the source host
segments long, application- layer messages (for example, an image
or a music file) into smaller packets and sends the packets into
the network. The receiver then reassembles the packets back into
the original message. We refer to this process as message
segmentation. Figure 1.27 illustrates the end- to- end transport of
a message with and without message segmentation. Consider a message
that is 8 · 106 bits long that is...

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 = 500 Kbps,
R2 = 2 Mbps, and R3=1 Mbps.
a. Assuming no other
traffic in the network, what is the throughput for the file
transfer?
b. Suppose the file is 4 million bytes. Dividing the
file size by the throughput, roughly how long will it take to
transfer the file to Host B?...

Multiple choice questions: Circle the correct answer
1) Suppose two hosts, A and B are separated by 1500 kilometers
and are connected by a link of R = 2 Mbps. Suppose the propagation
speed over the link is 3 x 108 meters/s. Considering sending a file
of 100,000 bits from Host A to Host B. Suppose the file is sent
continuously as one large message. The maximum number of bits that
will be in the link at any time is...

Characterizing Network Traffic
There are 1000 stations in a network. Each of the
stations transmit 5 frames/second and size of one
frame is 2000-bits. As, we know in addition to
application data, different protocols add differently sized header
with application data before they are sent through media. The
additional data from protocols are called overhead. For example,
TCP/IP add 20 bytes overhead, UDP adds 8
bytes overhead and Ethernet II adds 38 bytes overhead,
with each data...

Data
For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1,
7.0, 0.5, 3.9, 2.1, 4.1, 6.5
In Tasks 1-8 you are asked to conduct some computations
regarding this data. The computation should be carried out
manually. All the steps that go into the computation should be
presented and explained. (You may use R in order to verify your
computation, but not as a substitute for conducting the manual
computations.)

Pandora is the Internet’s most successful subscription radio
service. As of June 2013, it had over 200 million registered users
(140 million of which access the service via a mobile device) and
over 70 million active listeners. Pandora now accounts for more
than 70% of all Internet radio listening hours and a 7% share of
total U.S. radio listening (both traditional and Internet). At
Pandora, users select a genre of music based on a favorite
musician, and a computer algorithm...
