When deciding what technology to adopt for your computer network every business must understand the basics of that thought process. The truth is there’s benefits and drawbacks to each option. Choosing the right one can be complicated. So you’ll need to consider several factors before making a final decision.
You first need to thoroughly evaluate your current network. Uncovering and resolving any bottlenecks that might exist internally is crucial before spending potentially thousands of dollars on a new technology solution. You should start by creating some data models and using a network analyzer to get a handle on your network utilization. It’s a good idea to use a network modeling application to provide a more complete model of your network. This approach will provide you a more accurate assessment of your network performance and where there may be issues needing attention, if any.
Next, you need to identify your bandwidth requirements. The application(s) employed on your network currently, and planned for the future, is the most important measure when it comes to determining bandwidth. Let me repeat that…. it is crucial to consider both current AND future network applications. For example, if e-mail is the only application, an ISDN line should satisfy your bandwidth needs. Depending on the number of users you could probably get away with a simple T1 line or maybe a fractional T1 too. However, if there is a need to pump voice, data and video through the network, with guaranteed delivery, DS3 bandwidth or SONET (e.g. OC3 Bandwidth) is the best solution. Where available, Business Ethernet would be a viable option for this case also. If you are just looking to speed up access to the Internet, consider leased lines sized to the number of users and your projected saturation points.
