Routers are one of several types of devices that make up the "plumbing" of a computer network. Hubs, switches and routers all take signals from computers or networks and pass them along to other computers and networks, but a router is the only one of these devices that examines each bundle of data as it passes and makes a decision about exactly where it should go. To make these decisions, routers must first know about two kinds of information: addresses and network structure.

Routers are programmed to understand the most common network protocols. That means they know the format of the addresses, how many bytes are in the basic package of data sent out over the network, and how to make sure all the packages reach their destination and get reassembled. For the routers that are part of the Internet's main "backbone," this means looking at, and moving on, millions of information packages every second. And simply moving the package along to its destination isn't all that a router will do. It's just as important, in today's computerized world, that they keep the message flowing by the best possible route.

At the heart of a robust network foundation is the full-service router, intelligently forwarding data packets from one network to another. Regardless of your size, if you're serious about participating in the Internet economy, you need to select a business-class router that incorporates security, performance, reliability, and manageability. If you have more than one location today, or expect to in the future, look for a router series that provides the flexibility to use the most appropriate (and least expensive) connection service for each location, such as cable or DSL services.

Select the right hardware.
There are three things to consider when evaluating router hardware:

• How many ports the router has.
• What type of wide-area network (WAN) line the router operates over — for example, ADSL, DSL, ISDN, Fractional T1, T1, etc.
• Whether the router's wide-area network (WAN) interfaces are modular or fixed.

The first two considerations are fairly straightforward, based on the number of devices connected to the router (port capacity), and the WAN services that are appropriate for the traffic load on the network. The third consideration — fixed or modular configuration — depends on a company's growth requirements.

A modular router can be customized with a wide range of WAN and voice interface cards, which makes it a more flexible solution for companies that are in a period of rapid growth, or whose e-commerce initiatives might include multimedia services requiring some combination of data/voice/video/fax integration.

Know the load.

One of the key considerations in selecting a router is how much traffic it will be expected to handle — or, put another way, how much bandwidth the company needs.

Bandwidth is not dependent only on the company's size, but also on the type of business applications that are running on the network. For example, a network with a relatively small volume of e-mail but a lot of large file attachments (such as CAD files, graphics files, or video clips) may actually require more bandwidth than a network with lots of e-mail traffic but few file attachments. Similarly, two companies with the same number of online users may have different bandwidth requirements if all of the users are on the network simultaneously versus accessing the network at different times during the day.

The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G or Wireless-B devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices. Connect four PCs directly, or daisy-chain out to more hubs and switches to create as big a network as you need. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection."

Security devices

Because of the complexity of today's networks and the proliferating points of exposure, small businesses must think in terms of security solutions, rather than point products. A secure foundation network should include an integrated security solution encompassing virtual private networks (VPNs), firewalls, Network Address Translation (NAT), and intrusion detection. An integrated security solution closes the security gaps associated with multi-vendor solutions and is easier to manage and support and costs less to own. Also look for a security solution that is modular, so you can add components, scale, and choose integrated solutions (e.g., routers with built-in firewall) or dedicated devices as your business needs grow and change.
