Alternatively referred to as network traffic, traffic is a term used to describe all data communications on a computer or computer network. During high traffic periods a computer or computer network may slow down and become congested if not adequate for the load. In some cases, too much traffic may prevent a computer or network device from operating.
The traffic being experienced on a network can be monitored by taking the overall response times of all the major access points, such as all the primary routers and servers on a network. The longer response times is an indication of how much load is being experienced by that device. Sites like Internet Traffic Report display the traffic of the whole Internet by checking the response times of major points on the Internet.
