Federal Internet Exchange
Federal Internet Exchange (FIX) points were policy-based network peering points where U.S. federal agency networks, such as the National Science Foundation Network (NSFNET), NASA Science Network (NSN), Energy Sciences Network (ESnet), and MILNET were interconnected. Two FIXes were established in June 1989 under the auspices of the Federal Engineering Planning Group (FEPG). FIX East, at the University of Maryland in College Park, and FIX West, at the NASA Ames Research Center in Mountain View, California. The existence of the FIXes allowed the ARPANET to be phased out in mid-1990. FIX West was eventually expanded to become MAE-West, one of the NSF-supported Network Access Points.

Peering
In computer networking, peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the "down-stream" users of each network. Peering is settlement-free, also known as "bill-and-keep," or "sender keeps all," meaning that neither party pays the other in association with the exchange of traffic; instead, each derives and retains revenue from its own customers. An agreement by two or more networks to peer is instantiated by a physical interconnection of the networks, an exchange of routing information through the Border Gateway Protocol (BGP) routing protocol, tacit agreement to norms of conduct and, in some extraordinarily rare cases (0.07%), a formalized contractual document. In 0.02% of cases the word "peering" is used to describe situations where there is some settlement involved. Because these outliers can be viewed as creating ambiguity, the phrase "settlement-free peering" is sometimes used to explicitly ...

Internet Exchange Point
Internet exchange points (IXes or IXPs) are common grounds of IP networking, allowing participant Internet service providers (ISPs) to exchange data destined for their respective networks. IXPs are generally located at places with preexisting connections to multiple distinct networks, ''i.e.'', datacenters, and operate physical infrastructure (switches) to connect their participants. Organizationally, most IXPs are each independent not-for-profit associations of their constituent participating networks (that is, the set of ISPs which participate at that IXP). The primary alternative to IXPs is private peering, where ISPs directly connect their networks to each other. IXPs reduce the portion of an ISP's traffic that must be delivered via their upstream transit providers, thereby reducing the average per-bit delivery cost of their service. Furthermore, the increased number of paths available through the IXP improves routing efficiency (by allowing routers to select short ...

Commercial Internet EXchange
The Commercial Internet eXchange (CIX) was an early interexchange point that allowed the free exchange of TCP/IP traffic, including commercial traffic, between ISPs. It was an important initial effort toward creating the commercial Internet that we know today Goal The goal of the CIX was to be an independent interconnection point with no U.S. government-defined "acceptable use policy" on the traffic that could be exchanged; and just as critical, a "no-settlement" policy between the parties exchanging traffic. The no-settlement policy became a "given" during the modern era of the Internet, but was immensely controversial at the time. The great debate The early history of the Internet was dominated by U.S. government agencies such as ARPA/DARPA through ARPANET, the Defense Communications Agency (DCA) through MILNET, the National Science Foundation (NSF) through CSNET and NSFNET, the NSF sponsored regional research and education networks, and a handful of national networks spo ...

Stephen Wolff
Stephen South Wolff is one of the many fathers of the Internet. He is mainly credited with turning the Internet from a government project into something that proved to have scholarly and commercial interest for the rest of the world. Dr. Wolff realized before most the potential in the Internet and began selling the idea that the Internet could have a profound effect on both the commercial and academic world. Education Stephen Wolff earned a BSc with Highest Honors in Electrical Engineering from Swarthmore College in 1957, and a Ph.D. in Electrical Engineering from Princeton University in 1961. In 1962 he continued his studies with post-doctoral work at Imperial College. He taught electrical engineering at the Johns Hopkins University for ten years. Contributions to the Internet For fourteen years, Wolff worked as a communications and technology researcher for the United States Army. While working for the Army, Wolff introduced the UNIX operating system to Army labs in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MAE-West
MAE-West was an Internet exchange point located on the west coast of the United States in Silicon Valley, in the South San Francisco Bay Area in California. It was established in November, 1994. Its name officially stands for "Metropolitan Area Exchange, West", although it was a humorous reference to the name of the actress Mae West and to the original MAE in the Washington DC metro area, which was thereafter known as "MAE-East." The exchange was a dual FDDI ring, bridged between two locations, one in downtown San Jose, operated by Metropolitan Fiber Systems (MFS) and catering principally to smaller networks, and the second operated by NASA at Moffett Field, to the northwest, and catering principally to larger networks, since it had annual terms (rather than the monthly terms and Service level agreement available at the MFS location) and more restrictive access policies. The MFS side was constructed by Steven Feldman, and the NASA side by Bobby Cates and Lance Tatman. Its San ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARPANET
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. Building on the ideas of J. C. R. Licklider, Robert Taylor (computer scientist), Bob Taylor initiated the ARPANET project in 1966 to enable access to remote computers. Taylor appointed Lawrence Roberts (scientist), Larry Roberts as program manager. Roberts made the key decisions about the network design. He incorporated Donald Davies' concepts and designs for packet switching, and sought input from Paul Baran. ARPA awarded the contract to build the network to Bolt Beranek & Newman who developed the first Communication protocol, protocol for the network. Roberts engaged Leonard Kleinrock at Universi ...

National Science Foundation Network
The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) from 1985 to 1995 to promote advanced research and education networking in the United States. The program created several nationwide backbone computer networks in support of these initiatives. Initially created to link researchers to the NSF-funded supercomputing centers, through further public funding and private industry partnerships it developed into a major part of the Internet backbone. The National Science Foundation permitted only government agencies and universities to use the network until 1989 when the first commercial Internet service provider emerged. By 1991, the NSF removed access restrictions and the commercial ISP business grew rapidly. History Following the deployment of the Computer Science Network (CSNET), a network that provided Internet services to academic computer science departments, in 1981, the U.S. Natio ...

NASA Ames Research Center
The Ames Research Center (ARC), also known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley. It was founded in 1939 as the second National Advisory Committee for Aeronautics (NACA) laboratory. That agency was dissolved and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA) on October 1, 1958. NASA Ames is named in honor of Joseph Sweetman Ames, a physicist and one of the founding members of NACA. At last estimate NASA Ames had over US$3 billion in capital equipment, 2,300 research personnel and a US$860 million annual budget. Ames was founded to conduct wind-tunnel research on the aerodynamics of propeller-driven aircraft; however, its role has expanded to encompass spaceflight and information technology. Ames plays a role in many NASA missions. It provides leadership in astrobiology; small satellites; robotic lunar exploration; the search for habitable planets; s ...
