How Routing Algorithms Work

Think you know how routers work? These devices use intricate formulas to figure out exactly where to send a packet and how to get it there.  See more computer networking pictures.

If you have read the HowStuffWorks article How Routers Work, then you know that a router is used to manage network traffic and find the best route for sending packets. But have you ever thought about how routers do this? Routers need to have some information about network status in order to make decisions regarding how and where to send packets. But how do they gather this information?

In this article, we'll find out precisely what information is used by routers in determining where to send a packet.
