Networks - EduqasRouting

Static routing is similar to choosing a fixed route to school and never changing that route even if there is an obstruction on your route.

Dynamic routing is similar to a driver choosing different routes depending on traffic conditions, using devices that show traffic updates. These help them to choose the shortest and best possible route.

In computer networks, a system of scoring is used to determine the most efficient path for data to travel. These are based on factors such as:

• bandwidth – how much data a route can handle at a given time: the greater the bandwidth the more data can travel
• delay – looks at how long is taken for data to travel along a particular route
• hop count – looks at the number of devices (nodes) the data passes through to get to its destination
• reliability and traffic load – the routers on the network look at the links that are most reliable and give a better route for data through the network, depending on how much traffic (load) is on the link.
