Planning a Basic Network

Planning a network is usually broken down into 5 basic steps:


*Define objectives
*Evaluate current resources
*Develop a plan
*Review the plan
*Implement the plan


Defining objectives:

How many users? How many existing computers/devices?
How many new users? How many new computers/devices?
Future scalability
Network maintenance and administration


Evaluate Current Resources

Check hardware – make and model, system bus, NIC card characteristics, details of any other installed devices

Check software – programs installed, version number, and original disk availability, plus licensing information

Check connectivity – important if the network has WAN access

Check network resources – existing network resources, cabling layout, switching cabinets, existing conduits


Plan the work

Stay within the budget – but don’t use substandard materials!

Topology and type – with multiple devices in place and with a few central devices it could be a mix of bus, and star

Wireless options – if feasible a wireless solution for a network segment where physical cabling may not be practical

Selecting media – if new media is to be purchased, then factor in the cost for a new roll out as well – new media consideration include; the existing topology, size of the network, network devices including workstations, security, physical considerations

Logical and Physical mapping – put a layout of the network on a piece of paper, the best option is to start with the physical layout then draw the logical connections

Some common considerations – there is no right way to design a network, there are as many design preferences as there are designers. Some considerations however remain and have to be answered: How many users? - Restrictions and regulations concerning data for the users – central administration – centralised servers – how many servers will your network have? – is there a secure room for the servers – is automated troubleshooting important? – can the existing wiring in the building be used for your network?
