2.2.4 Internet service providers

In centralised and distributed data storage environments, data must be transported over the network or internet.

Devices that forward data across the internet must use an internet service provider (ISP). An ISP supplies the connections to allow internet access to individuals and businesses, and can also interconnect with other ISPs. Networks connect to an ISP at a point of presence (POP).

Within an ISP, a network of high-speed routers and switches move data between the various POPs. Multiple links interconnect the POPs to provide alternate routes for data in the event that one link fails or becomes overloaded with traffic.

To send information beyond the boundaries of an ISP network, packets are forwarded to other ISPs. As shown in the animation, the internet is made up of high-speed data links that interconnect multiple ISPs together. These interconnections are part of the very large, high-capacity network known as the internet backbone.
