INTRODUCTION•An Internet service provider (ISP), also sometimes referred to as an Internet access provider (IAP), is a company that offers its customers access to the Internet.•The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol packets or frames, such as dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects

End User to ISP Connection ISP employ many technologies

for users to connect to their network such as-

Dial-upDSL ( Digital Subscriber Line)broadband wirelessIntegrated Services Digital

Network (ISDN)

ISP Interconnection Just as their customers pay

them for Internet access, ISPs themselves pay upstream ISPs for Internet access.

An upstream ISP usually has a larger network than the contracting ISP and/or is able to provide the contracting ISP with access to parts of the Internet the contracting ISP by itself has no access to.

Peering

ISPs may engage in peering, where multiple ISPs interconnect at peering points or Internet exchange points (IXs), allowing routing of data between each network, without charging one another for the data transmitted—data that would otherwise have passed through a third upstream ISP, incurring charges from the upstream ISP.
