Q1: STONEHENGE ENGINEERING WORKS: Stonehenge Engineering Works is a small company that specializes in complex engineering consulting projects. Most Engineering projects need large data transaction. The company is moving into new offices and ask you to design their data communication network. They are going to have two divisions in two different office sites in the same building, (two story office building)

Engineering division in the first floor : They have a staff of 10 engineers (which is expected to grow to 15 over the next five years) and the database for the product development. Engineering division will be using 3D design and online collaborations tools which require large bandwidth and fast data communication.

Management division in the second floor : There are 20 management and clerical employees who also need network connections, but whose needs are less intense. This site has database for the clients as well.

All employees in the building should be connected via company intranet.

1. Draw the Backbone network diagram for Engineering division
2. Draw the Backbone network diagram for Management division
3. Draw the Backbone network diagram to provide intranet connection to all computers.

Clearly indicate whether you would use switch, router or gateway in the diagrams.

Q2 SILVER KNIGHT’S HOTEL : The Silver Knight’s Hotel is a luxury hotel that whose guests are mostly business travelers. To improve its quality of service, it was decided to install network connections in 50 guest rooms and 2meeting rooms. All guests and employees should have connection via internet as well.

There are three sections in Silver Knight’s Hotel building;

Section 1: 50 guest rooms (one physical computer connection in each room)

Section 2: 5 meeting rooms with 10 computers with one printer in each. There will be printer server for meeting rooms room. That is two LANs

Section 3: The management office site has one LAN with, 10 desktop computers, Print sever, Mail server, Web Server and Printer.

Assume, there is No Wi-Fi in the Hotel building. And, one switch can connect max 25 computers

Your task;

1. Draw the Network diagram for 50 guest rooms.
2. Draw the Network diagram for 5 meeting rooms with 10 computers
3. Draw the Network diagram for the management office site
4. Design the network to connect the all three networks together and to the internet.

Clearly indicate whether you would use switches, routers or gateway in your network diagram.

Q3 GOLDSTAR BANK : GoldStar Bank is helping companies to do money transaction for their customers who holds their credit card (GoldStar Bank Credit Card). Please consider the following parameters:

• The Bank’s has one Data Center where it keeps all customer data transactions. Data Center in a building in NYC.
• GoldStar Bank has only one building in NYC where all employee computers are connected to each other and the main database via INTRANET.
• The Bank’s database can be accessed remotely by the companies. Currently, there are five companies accepting the GoldStar Bank Credit Card in their stores. All, these companies are connected to the GoldStar Bank Data center via Wide Area Network (WAN).
• GoldStar Bank Data center has been proving service to the companies via Wide Area Network (WAN).

There are five companies already accepting GoldStar credit card. And, there are located at;

Miami FL Needs 2Gbp data speed to reach the GoldStar server in NYC

Dallas TX Needs 20Gbp data speed to reach the GoldStar server in NYC

Los Angeles CA Needs 40Gbp data speed to reach the GoldStar server in NYC

Chicago IL Needs 45Mbp data speed to reach the GoldStar server in NYC

Develop the Network Architecture diagram for this case by presenting Wide Area Network (WAN) Model. In your network diagram, present the followings;

1. WAN Topology diagram on a USA map.
2. In a table formant, write WAN services for each company connection that meets the data speed requirements
3. All four sites and GoldStar Bank Data center have connection to the internet. Show the connections to internet on the same Network diagram
