Objectives

In this project you are required to design a network for a typical company that requires its

computers to communicate with each other and on the internet.

Company Requirements

A new education centre has just opened up with the aim of offering IT related courses to its

students. It aims to provide student labs, provide

computers for its education and administrative staff and also set up a web server. The company has

just purchased one T1 connection providing 1.5Mbps for upload and download. It has also

purchased the 193.188.34.128/26 network from its ISP.

It terms of PCs, the centre has the following plans:

Σ It wants to setup 1 web server to host the centre's website and also 1 file server on which its

students can access course materials from home. Each of these will be allocated a different

DNS name.

Σ The centre wants to set up two computer labs, each containing 15 PCs with each having

internet connectivity.

Σ Additionally it wants to allocate 7 PCs, each of which will be placed in different classrooms

and are to be used by the course tutor. These PCs also require internet connectivity.

Σ 2 PCS will be given to the system administrator, with the facility to provide any type of

Internet services on them.

Σ Also 5 PCs will be made available for administration and another 3 for tutors. Please note

that management have decided that these PCs should not get internet connectivity.

Introduce Vlans for efficiency.

Σ And finally a wire-less network should be made available to students which can allow

students internal access to the file and web server but not to the internet.

Your task is to come up with a logical, efficient and scalable network design that will be suitable for

this centre. The company has allowed an adequate budget to purchase any switches and routers

that may be required, yet obviously does not want to spend more than necessary.

Design Details

When drawing up your network designs make sure you split the design up in a way that emphasizes

the function of the components. In addition, make sure that no malicious user would be able to

circumvent the system. Additionally, make sure that all sub-networks are split up allowing them the

fastest access possible depending on their requirements. Also keep the design as simple as possible

allowing efficient troubleshooting while guaranteeing the least downtime in the system. As a hint

always split up networks in terms of function, since PCs with similar function most probably will

often communicate between themselves. Also do not forget about the ISP link!!

Deliverables

Build a document giving all the necessary network designs (enough information should be provided

that will allow any technician to build your network structure from scratch). You are requested to

depict the network setup by means of diagrams showing the division of the networks and their

interconnections. Please make use of standard depictions for components. Also include a .doc or

.pdf file (called tables.doc or table.pdf) containing the routing tables of each and every router and PC

in your network diagram. Make sure you include the subnet masks and the default route. Obviously

the smaller the tables the better, since the cheaper the routers can be. Also include any other

necessary information such as ranges of ports when using NAT, allocation policies if using DHCP,

limitations of any technique used, etc. You are free to make use of any trick in the book to setupObjectives
