Internet service providers participate in Internet backbone traffic by privately negotiated interconnection agreements, primarily governed by the principle of settlement-free peering. The interactions between large corporations and their agreements for sharing each other's networks also tend to complex business dynamics.ĭue to their central role on the Internet and global communications, backbone installations are a prime target for malicious attacks. Instead, the networks of Internet service providers or large organizations connect to these backbones and computers access the backbone indirectly. Computers rarely connect to a backbone directly. Each fiber link on the backbone normally provides 100 Gbps of network bandwidth. They consist of network routers and switches connected mainly by fiber optic cables. Nearly all Web browsing, video streaming, and other common online traffic flows through Internet backbones. These data routes are hosted by commercial, government, academic and other high-capacity network centers, the Internet exchange points and network access points, that exchange Internet traffic between the countries, continents and across the oceans. The Internet backbone may be defined by the principal data routes between large, strategically interconnected computer networks and core routers on the Internet. The best-known network backbones are those used on the Internet. The Internet backbone is made up of many large networks which interconnect with each other. Network backbones are designed to maximize the reliability and performance of large-scale, long-distance data communications. In computer networking, a backbone is a central conduit designed to transfer network traffic at high speeds. Backbones connect local area networks (LANs) and wide area networks (WANs) together. The Internet generates massive amounts of computer-to-computer traffic, and insuring all that traffic can be delivered anywhere in the world requires the aggregation of a vast array of high-speed networks collectively known as theIinternet backbone. Data being transported at 300 Mb/s, for instance, requires a minimum of 1 gigabit of ethernet transport.
In order to successfully transmit data, a minimum bandwidth is required which depends on the data being transported. This physical route of cables is called the transmission medium. Each transmission medium is restricted to a fixed capacity known as the the bandwidth.
The data then travels through a physical route to its destination, commonly consisting of a possible mix of co-axial cables, a twisted-pair cable, or fibre optics. The data is first broken into small packets of information, as it cannot be sent whole.
