CASE 1: FSI Test Equipment Incorporated:
Precision test equipment manufacturing
FSI manufactures high-end, high-volume semi-custom test equipment. Though the company
only employs 150 people, sales revenue and profitability are very high because of niche
market control and product price levels. Each piece of equipment is built to order and goes
through rigorous testing and integration. As a result of market dominance, growth and
profitability, company management has decided to make an initial public offering (IPO) of its
stock.
FSI has customers through out the world. Because their equipment integrates so tightly with
customers’ high tech manufacturing systems, the company in reality becomes a partner with
its customers during the design, manufacturing, and testing of the equipment. Purchase order
to operational date cycles are typically one year and approximately five systems are in the
development cycle at any gives time. Timely, accurate, and secure communications with the
customer throughout the cycle is in imperative. Hardware design involves a significant
number of CAD drawings to be stored and transmitted. Software development requires
hundreds of thousands of lines of code for each customer. Though much of the code is reused,
it nonetheless requires configuration and revision control for each customer.
With funds raised from the IPO, FSI wants to improve its ability to interface, communicate
and respond to its customers. It wants to implement secure FTP of code and drawings to its
customer. Security is of utmost importance and therefore FSI is not sure if can trust the
Internet to accomplish these transfers. Because of financial concerns, the company would
much prefer the Internet to a private network if it can be convinced that the transfers can be
made secure. Otherwise it will consider a private network.
The company also would like to implement an inter-company workflow system for routing of
electronic forms between FSI and its customers world-wide. Again, security is the issue. It
would be wonderful if they can use the Internet for both these functions, but the new board of
directors must be convinced. FSI offices are in San Jose, California. The project team
assigned to customers has two sub-teams: the manufacturing and development team in San
Jose, and the integration teams moves on site to the customers’ facilities. Communication is

by telephone, e-mail, and even overnight package delivery.
25% of FSI employees (38-40) people are housed at customer sites at any given time. These
field persons are in teams of approximately 8 people. A Novell PC LAN on Ethernet is
established for each team within the customers’ facilities with a dial-up Internet connection
using Livingston router for e-mail. In the San Jose office, FSI has two LANs with 80 PCs.
The main LAN has 5 sun AutoCAD workstations that will use the test software, 20 Pentium
UNIX engineering workstations for software development on one segment, and 50 office
automation desktops running the Lotus Suite on another segment. These two LAN segments
are connected to a Novell server with the two Ethernet cards as the only routing mechanism
between the two.
The second LAN has five processes monitoring an analysis PCs that collect and analyses the
test data. This data is accesses continuously by the engineering staff from their workstation.
The two LANs are networked with a third Internet card in the Novel server. Engineering staff
is frequently frustrated with the performance across this link. You have been asked to provide
a design and justification for an intranet/Internet bases solution that will convince the board of
directors that the solution is viable and secure.

CASE 2: EIC Satellite Systems:
Digital satellite television programming sales
EIC sells minidish satellite systems and television programs in central Europe. Its sales
network comprises 10 company owned offices, 25 distributed sales and installation offices
www.correctexams.com

and a central office in Milan, Italy. In the central office 75 representatives provide 24 hour
telephone support and order processing for programming changes. There are 200 employees
in the central office with PCs running Microsoft Office in addition to telephone

representatives. The company’s order processing, billing, accounting and programming
systems reside on a large AS400 system in Milan. The 10 company offices are connected to
this system with 9600bps leased lines. 25 distributor offices dial in to the system twice a day
to upload order and download installation work order.
An Ethernet LAN with three Novel servers supports the 275 central office employees. On
average, the 10 offices have 4 PCs connected via Ethernet with Microsoft Windows 95. The
leased line in each office does not provide a touted connection but a serial connection of 5250
terminal emulation to the communication port on the PC. The 25distributer offices dial in to
the three PC Anywhere remote control computers that run 5250 terminal emulation and
scripts that download installation work orders and upload new account orders to the AS400.
To reduce transaction processing coast EIC will implement intranet technology to replace the
current data communication mode. A Web server will be installed on the AS400 with back-
end CGI that will interface to the order processing, billing and work order system. Java
applets will be built for both remote PCs. EIC anticipates that these changes will allow it to
handle twice the transactions without upgrading the AS400, while maintaining current
transaction processing times. The company offices will be connected via ISDN routers using
bonding between channels for the new browser-based applications. Similar browser-based
connections will be accomplished for the distributor offices using a direct dial to the EIC
Milan main office. Unless convinced otherwise, EIC intends to use the existing 9600bps lines
for the routed connections.
It is also desirable to provide an in Internet dial-up connections for customers to make their
own configuration changes online and to order pay-per-view programming. Security for these
transactions will be provided by secure Web transactions. Data transmission encryption is not
necessary because these basically are secure Web-based credit card transactions.

EIC would like a design and proposal from you to provide the networking for this new
architecture that must be implemented in parallel with current operations.


CASE 3 Orchard Leasing Corporation:

Office building leasing and facilities management

- 5 -

Orchard Leasing is a contract leasing and facilities management company with headquarters
in Denver, Colorado and offices in Houston, Texas, Atlanta, Georgia, Minneapolis,
Minnesota, Chicago, Illinois. Orchard contracts with owners to provide leasing, maintenance
and management of high-density office buildings and building complexes. A local office is
maintained in one building in each of the cities. The company’s superior service and creative
and aggressive marketing has lead to very rapid growth in each of the Orchard’s
marketplaces. In fact, Orchard has just signed contracts for four buildings in London, England
and three buildings in Frankfurt, Germany. However this growth has out stripped Orchard’s
ability to keep up with administrative tasks associated with business, and management is very
concerned about its ability to continue to provide the same level of service, given the two new
international contracts.
Each of the offices has historically maintained its own operation center including a Windows
NT file server with leasing, marketing, maintenance, and facilities management (including
billing) software, as well as standard office productivity software provided by the
WordPerfect suite. The business applications are all custom are all custom applications
developed in Access and Visual Basic. Each office has an Ethernet network on 10BaseT
cabling. The leasing and marketing software systems run on Apple Macintosh and
maintenance and facilities management runs on Intel-based PCs. Typically, there are five PCs
and two Macintoshes in an office. The Denver office has six PCs and three Macintoshes but
will increase those numbers to ten PCs and six Macintoshes after the proposed upgrades.
Data is consolidated monthly in an office report sent by e-mail via the Internet to the home
office in Denver. This Internet connection is by way of local ISP on a dial up connection.

With the addition of the London and Frankfurt offices, Orchard had decided to consolidate a
www.correctexams.com

- 6 -
significant portion of administrative tasks in Denver. The lease administration, tenant billing,
accounts receivable accounts payable, and master building records will all be consolidated in
Denver. The marketing, maintenance, and office productivity software will continue to reside
in the branch offices. The number of computers, servers and Macintoshes and PCs will remain
the same as the branch offices but a new NT Server and the additional Macintoshes and PCs
will be added in Denver.
With this upgrade, Orchard will add Microsoft’s Exchange with outlook for e-mail,
scheduling, and contact management. The current branch office files servers will have less of
a load and therefore Orchard believes they will be able to run Exchange Server and the
existing server hardware with additional memory and disk space. Additionally, Orchard will
be establishing a World Wide Web site in Denver to be used for marketing and
communication to tenants.

Orchards new chief financial officer (CFO), who has responsibility for computer and
information systems, has requested competitive bids for a turn-key WAN to meet Orchards
needs. High performance across a WAN is not seen as a priority. The communications that
will occur between offices are “back-office” functions and are not time critical.
Accomplishing the transmissions this morning rather then tomorrow is the level of
criticalness. Minimising cost will take priority over unneeded performance. The CFO
estimates that beyond e-mail, which will be normal, there will be a daily transmission of
records for consolidation both to and from each office and Denver each day. These documents
are approximately 2MB in size.



CASE 4: Leviathan System’s Inc:
Business software development, publishing, and sales
Traditionally, Leviathan has developed and sold AS400 business software solutions. In
addition to its headquarter office, it had five sales offices in United States, a European office,
and an Asian office. It is converting its software to Windows NT client/server technology
using SQL Server as the database engine for the new project line. The offices are connected
with a point-to-point SNA network with line speeds varying from 56k to a Frac T1. Token
Ring is installed within the office for LAN applications. Each of the facilities is wired with
Category 5 cable in an Intermediate Distribution Facility/Main Distribution Facility
(IDF/MDF) design The company recently decided that it must completely convert the Token
Ring to Ethernet. This conversion will first occur in the HQ facility and then in each of the
branch offices. The conversion will occur one IDF at a time, that is, the Token Ring and
Ethernet networks will coexist as work groups are converted.
The client-server products will be added, but the AS400 product line will not go away.
Therefore, SNA will be a fact of life for the foreseeable future. The customer prefers to have a
single WAN but has decided to look at a frame relay solution to transport the client/server
traffic and keep the SNA network intact. Some TCP/IP is in use, but only at the local LANs.
The AS400s are connected to the Token Ring via a 5294 controller that provides the terminal
server functions between the LANs and the AS400. Leviathan considers it too expensive and
problematic to put the AS400 on Ethernet, so management would consider maintaining the
AS400 on a small, four -node Token Ring network and put the rest of the company in
Ethernet.
There are 56 5250 terminals in the HQ office and the sales office, each has approximately
6PCs running 5250 terminal emulation, including the Europe and Asia offices. The 5250
terminals will be converted to PCs using the 5250 terminal emulation software. The HQ office
also had 100 PCs and 5 Macintoshes (for production of marketing material and product
www.correctexams.com

documentation). Additionally, there are two notebook computers in each sales office. These
notebooks already use terminal emulation to dial into the AS400 for demonstrations and sales
reporting. This dial-in functionality must continue to exist for the AS400 and must be
provided for the new client/server products. There are four AS400 at the HQ office facility
and one each in two if the US sales offices, the European office, and the Asian office. Four
Windows NT servers will be located at HQ, and a small NT server in each of the sales offices.
Most of the 100 PC’s in HQ run 5250 terminal emulation, which utilizes NEtBIOS.
Two NT Servers are at HQ. Two additional servers will be installed for a total of four
Windows NT Servers, two for development (a Digital Equipment Corporation Alpha and a
Hewlett-Packard multiprocessor Pentium), one for Sales and Marketing, and one for all other
support. Software development traffic to the AS400 occurs around the clock but peaks from 1
to 7 p.m. The development effort on the new product is expected to follow the same pattern.
15 new employees will be hired for this development effort. All other use of the network
occurs in normal business hours. Leviathan will install an Internet server hosted on an
additional Windows NT system. It will provide a World Wide Web presentation of Leviathan
products and an FTP server to deliver product updates and fixes. It will also host a discussion
group system and SMTP and POP3 servers for e-mail to customers and prospects. The site
must provide secure FTP and a firewall to protect Leviathan internal systems. Leviathan has
standardised Microsoft Office for office productivity and Microsoft tools for development of
its new product line.
Company email is provided by a system on the AS400. This system will be converted to
Microsoft Exchange, but not as a part of this project.
The IS manager has asked for a design to connect all the offices to provide the Ethernet
connectivity within the HQ office and to provide for the Internet firewall.
