Buy network processors specifically made for a business of your size

Many processors are optimized for mid-size or home businesses. If you're planning to use your computer network processors on a larger scale, you'll need to find a network processor vendor that caters to large business networks by providing extra ports and more bandwidth. Make sure your network processor supports multiple wide area networks (WANs) if you plan on connecting more than one network to your processor.

I recommend: Consider Hifn's 5NP4G network processor for light business use. Mindspeed's EdgeMaker series can handle heavier traffic loads.

Check for voice over IP Support when picking a network processor design

To work with voice over internet protocol (VOIP), network processors should have at least two high speed ports capable of connecting to SLIC/CODECs or T1/E1, as well as good network security. Processor models sometimes provide even more robust support for VOIP, so if your company plans to do a lot of calling it's best to consider your options.

I recommend: Choose a model like Xelerated's HX330 Series or LSI's APP3300 model, which is designed for telecom equipment.

Look for a Tolly testing certificate when browsing network processor manufacturers

Tolly is an independent testing company that reviews network processor features and hardware by using performance benchmarks and testing. Tolly regularly issues reports on network processors that detail the good and the bad, along with comparisons between rival technologies.

I recommend: Check out the Tolly-certified S7900E model from 3Com, or Intel's IXP2XXX product line, which is also Tolly certified.
