NTC 249 Entire Class Wide Area
Networking Concepts
Discussion Question 1
Write a 250- to 300-word short-answer response to the following:
· What are two WANs that you
have used? What equipment or devices were used? Describe the network design and
configuration? Respond to your classmates, and discuss how your examples
differ.
Discussion Question 2
Write a 250- to 300-word short-answer response to the following:
· Chou (2009) discusses a very
common situation in business, communications between branch offices, and the
home office data center. The author presents two methodologies to improve
throughput between the offices and the data center: data compression and
caching. Analyze and discuss the common types of data used in your company to
test the suitability of these methods. Additionally, discuss where, in general,
data compression can be used and where data compression cannot be used.
Discussion Question 3
Write a 250- to 300-word short-answer response to the following:
· Soares, et al. (2008) review
all the present protocol segments necessary for VoIP telephony. Protocol such
as Session Initiation Protocol (SIP) and H.323 are prevalent but have
limitations. Analyze and discuss the limitations of SIP and H.323 as presently
used and include in your discussion effects of the proposed Advanced Multimedia
System (AMS) protocol and whether it will fix the existing problems.
Discussion Question 1
Write a 250- to 300-word
short-answer response to the following:
· What are the advantages
and disadvantages of VoIP? What VoIP services exist? What equipment may be
necessary in a small office/home office (SOHO) and large enterprise
environment?
Discussion Question 2
Write a 250- to 300-word
short-answer response to the following:
· The Internet does not
guarantee delivery. Multimedia services such as Internet Protocol television
(IPTV) require levels of quality of service (QoS) for acceptable performance.
Doverspike et al. (2009) have created a set of internal protocols that help
create a QOS scenario to allow IPTV signals to be delivered in an acceptable
fashion. Pick any two of the author’s techniques and show how they contribute
to the creation of a data stream with QOS.
Discussion Question 3
Write a 250- to 300-word
short-answer response to the following:
· Based on the Khan and
Tahboub (2009) article, analyze and discuss the advantages and disadvantage of
the MPLS protocol and what services are most likely to use that protocol in the
network.

protocols?
· On which OSI layers do
switches and routers operate?
· If routers reside at more
than one layer, what is the difference between the OSI layers?
Discussion Question 1
Write a 250- to 300-word
short-answer response to the following:
· Conduct an Internet
search to locate an example of a private network and a public network. How is
each network used? What are the pros and cons of each?

short-answer response to the following:
·Explain sub-netting in a way a
nontechnical client would understand. Add clarification to other student
explanations.
Discussion Question 3
Find a web site, an article on a web
site or a peer reviewed article that is related to this weeks material.

Short Answers
Provide answers to each of the following questions:
Identify the functions of a CSU/DSU.
How are they used in a corporate environment? Integrated services digital
networks (ISDN) are sometimes used in locations that do not support DSL or
cable modem connections. Your choices may be analog modems or an ISDN
connection in those remote locations. Describe three benefits ISDNs have over
regular dial-up modem connections. Compare and contrast packet and circuit
switching. Which is more commonly used? What are the advantages and
disadvantages of each? Describe the three main types of firewalls. Explain how
each type protects the network. Determine which firewall is the most efficient
and why.
Your answers should be 3-4 pages
long in total (400 words per page).
Discussion Question 1
Write a 250- to 300-word
short-answer response to the following:
· What are some of the
greatest security risks to a WAN? Provide an example of one risk and discuss
the potential consequences and possible precautions.
Discussion Question 2
Write a 250- to 300-word
short-answer response to the following:
· Network attacks come in
many forms. Broadley, et al. (2009) point out a new method where the attacker
creates a covert communication channel by changing the timing of part of a real
signal and sneaking in. Analyze and discuss whether your system at work could be
attacked by this methodology and if you think so what are you going to do about
it?
Discussion Question 3
Find a web site, an article on a web
site or a peer reviewed article that is related to this weeks material.
Write a 250-300 word synopsis what you have found and explain why you think it
is relevant. Make sure you include the references and links to the
article or web site.

VLAN Paper
Consider the following scenario:
Your Company moves into a new
building. Marketing is on the first floor, engineering is on the second floor,
operations are on the third floor, and the call center is on the fourth floor.
The LAN is organized neatly, with each floor having its own switch. Some of the
groups on the floor are connected through hubs and the network is planned for
orderly growth. The company grows faster and much differently than was planned,
however, and the call center must be expanded. Some of the engineering
department employees on the second floor and operations employees on the fourth
floor move offsite, and the call center expands. Space is compressed and users
move to other parts of the building, but their communities of interest do not
change. The same users still need to communicate with the same services.
Write a 3-4 page plan (400 words per page) explaining how a VLAN
could be implemented so that bandwidth is not consumed. Your plan must ensure
that the network is not flooded with packets, and that members of the same VLAN
can be located in different buildings or cities. Include the following:
· The benefit of creating a
VLAN.
· A plan to segment the
network into different broadcast domains to avoid bandwidth consumption.
· A plan to improve security.
· The type of VLAN membership
and the value of that choice over other options.
· The type of switch to be
used, layer 2 or layer 3, and why you would choose it over the other.
· The types of trunking
configured on the switch.
· The purpose and benefit of
using the VLAN trunk protocol (VTP).
· A definition of the VTP mode
used to configure the switches.
· Backup plan.
Your answers should be 4-5 pages
long (400 words per page).
Discussion Question 1
Write a 250- to 300-word short-answer
response to the following:
· How can wireless interface
with a WAN? Discuss security concerns with wireless and best practices to
protect a wireless system?
Discussion Question 2
Write a 250- to 300-word
short-answer response to the following:
· Worldwide Interoperability
for Microwave Access (WiMAX) is a very popular topic today since it offers the
possibility of wireless broadband signal capability over large geographic
areas. WLAN signals suffer from a number of potential degradations such as multipath
and fading. Balakrishnan, et al. (2009) analyzes the WiMAX technology in these
conditions. An interesting side note to recognize is that this analysis was
done via computer simulation using software called OPNET. Analyze and discuss
the potential for the use of WiMAX in your corporate environment. Do you see
WiMAX becoming the predominant WAN wireless technology of the future? If so,
why? If not, why?
Discussion Question 3
Write a 250- to 300-word
short-answer response to the following:
· Li, et al. (2009) have
provided a brief review of early network structures and are also providing
their view of the future generations of wireless networking out to the 7th
generation. Analyze and discuss you personal view of either agreement or
disagreement with the authors. In either case present support or alternatives.
