A Cisco WAN is a very powerful tool for companies that have multiple networks or LANs (local area networks) separated by distances, be they across the state, across the nation or across the world. As long as there are good telecommunications lines between the networks, the Cisco WAN allows computer users to access network resources as if they were in the same building or the same LAN. This makes collaboration across distinct offices much easier.

To create a Cisco WAN, you will need several different components. These components work together to connect the various networks and to keep them secure. These components include, but are not limited to:

1. Cisco WAN routers
2. Cisco WAN switching
3. WAN switching software
4. Cisco WAN accelerator

In addition, to make a Cisco WAN work, you will need someone who knows Cisco WAN configuration. Configuring a WAN allows it to operate at peak efficiency. If you want to install or upgrade a Cisco WAN, consider the following actions.

Action Steps
The best contacts and resources to help you get it done

Comparison shop for your Cisco WAN router and WAN switching software and firmware online

Cisco is perhaps the most recognizable name in WAN routers, switches and software. Because of this, there are numerous online distributors and resellers of Cisco WAN equipment.

I recommend: Look for new Cisco WAN equipment at Super Warehouse. You can also comparison shop other leading manufacturers there. In addition, use a company like Northland Systems to get prices on used Cisco equipment.

Research Cisco WAN optimization strategies online

Cisco WAN optimization will make the most efficient use of network resources. It also provides a WAN that operates more quickly for the least amount of money and the small utilization of electricity. However, Cisco WAN optimization, or optimization of any WAN, is an art form and requires training and experimentation.

I recommend: Look at companies like Blue Coat, which offers a free whitepaper on Cisco WAN optimization. Call them to assist in an optimization effort. In addition, Cisco itself has primers and training on optimizing its WAN.

Buy Cisco MGX 8950 software and switching along other MGX 8xxx products

The MGX (including MGX 8250 software and Cisco MGX 8230 software) line of switches are some of the most sought after Cisco WAN equipment, which makes them easy to find online. These switches offer a high degree of functionality. Evaluate them for use in your Cisco WAN, even if you had an eye on another model.

I recommend: Check out SwitchXchange, Inc. for prices on any 8xxx series switch. In addition, the Google Products website has ways to purchase the Cisco 8950 software and switch.
