![]() This growth will continue into the foreseeable future as the nature of the network evolves and more devices such as cellular phones, PDAs and even common appliances are brought online. From its humble beginnings in the academic research community to its current state, the Internet’s infrastructure grew in a relatively short period of time as private sector providers scrambled to meet the rising public demand for greater access and band Other lists will be geared toward providers with national or regional focus. The general criteria for being on this list are that a network must a) substantially serve multiple locations on three continents, or b) be continent-wide in both North America and Europe. The lines represent connections between routers in major urban areas throughout the country. This page will hold links to maps provided by international backbone providers. Eventually the private sector had built sufficient Internet infrastructure that NSFNET was decommissioned.Ĭredit: Zina Deretsky, National Science FoundationĪ visualization of Internet connections in the United States. In less than ten years, traffic on NSFNET grew at a rate of 20% a month as more and more users came online. Science Foundation created NSFNET, which provided a backbone network, shown in the bottom illustrations, for regional academic networks to connect to the national supercomputer centers and with each other. By the 1980s, it was clear that networking had great potential to assist academic research. By the 1970s, DoD expanded its network to include several research universities and laboratories. The Internet began as an experiment in computer networking by the Department of Defense (DoD) in the late 1960s. ![]() ![]() These four maps show, in clockwise order, the growth of the Internet from its beginning to 1995, when the NSFNET backbone was decommissioned and the private sector took over its operation.
