Like bridges, routers connect two or more networks. However, routers are much more powerful than bridges. Routers can filter traffic so that only authorized personnel can enter restricted areas.


They can permit or deny network communications with a particular Web site. They can recommend the best route for information to travel. As network traffic changes during the day, routers can redirect information to take less congested routes. If your school is connected to the Internet, then you will most likely use a router to make that connection.


Routers ensure that your local area network traffic remains local, while passing onto the Internet all your electronic mail, Web surfing connections, and other requests for Internet resources. Routers are generally expensive to purchase and difficult to configure and maintain. Be sure that your staff have the resources necessary to manage them well. Routers quickly become critical components of your network. If they fail, your network services will be significantly impaired. As part of your network plan, you should consider how you might deal with the failure of key routers on your network. Many sites include redundant connections—additional routers and network cable connections—configured to take over if one router or connection fails.


Most routers operate by examining incoming or outgoing signals for information at OSI level 3, the network addressing level.
