Internet traffic is the flow of data across the Internet. Because of the distributed nature of the Internet, there is no single point of measurement for total Internet traffic. Internet traffic data from public peering points can give an indication of Internet volume and growth, but these figures exclude traffic that remains within a single service provider's network as well as traffic that crosses private peering points. The phrase "Internet traffic" is sometimes used to describe web traffic, the amount of data sent and received by visitors of a particular web site.
