Delving Into The Series Of Tubes: How Internet Backhaul Works And Why We Need More

Europe has moved to this model, while the U.S. has a slightly different for-profit IXP model that may be transitioning over to the more cooperative European model, thanks to the Open Internet Exchange organization . But IXPs are only part of the problem. First, a bit about backhaul. The internet is a series of networks that connect to each other at interconnection points located in data centers. Your ISP provides whats known as last-mile service, which goes from a business or home back to a central office or head end owned by the ISP. At that point, your traffic heads out to a transit provider that connects to networks owned by content companies, retailers and clouds. If the traffic needs to cross the ocean, it will travel on submarine cables . These transit providers long-haul and middle-mile networks, as well as the submarine cables, are all examples of backhaul how last-mile traffic gets back to the internet itself. The report concerns itself mainly with submarine cables, though. Many developing areas need more pipes connecting them to other parts of the world. This is both an economic issue (more competition between pipe owners lowers prices) as well as a resiliency issue (more pipes ensure that cable cuts will not shut down the communications network ). Not only do these areas need more submarine cables, but the ownership structure is changing, with big internet companies like Google and Facebook investing in backhaul at the submarine cable level as well as long haul fiber across countries. The OECD report lays out a detailed history of how liberalization and increased competition on the submarine cable side can lower prices and boost demand for internet-based services.
