Tier-One Provider - Networking
A tier-one internet service provider is an ISP that does not use any other ISP to transfer data across the country. These ISP's typically have private peering arrangements to exchange data directly with other ISP's. These providers typically have multiple connections across the country so that if one connection fails, data can be re-routed along other links.
