The Internet backbone is a conglomeration of multiple networks, routing facilities, and servers that provide a multiple redundancy approach to keeping information online available and secure. Simply put, it enables back up networks to take on the load of a failed network or multiple failed networks.
Each ISP (Internet Service Provider) is equipped with its own contingency backbone network or is at least equipped with an outsourced backup. These smaller networks are interlinked and intertwined to provide the multi-faceted backup redundancy needed to keep the web intact in case of partial failure through peering and transit agreements.
Peering is the term assigned to the sharing of Internet traffic and users voluntarily by multiple networks, typically privately owned by companies. Peering typically refers to these networks being shared with no monetary gain being obtained by their owners. Rather, an agreement is made between multiple parties to handle each other’s traffic in times of need, with each network gaining its revenue from its own customer base. A transit agreement is a particular type of peering arrangement between ISPs that may contain a monetary agreement. Generally larger ISPs will create multiple transit agreements with smaller ISPs that are in need of additional facilities than they possess.
With each passing year, the importance of the World Wide Web and its contents increases exponentially. As more users log on each day, the need for a worldwide redundant communication and storage network becomes more imperative to effective and reliable commerce and stability. The backbone of the Internet will continue to evolve and progress in relation to increased needs of the world economy and interconnectivity of its users.
