The Ohio Academic Resources Network (OARnet) is a state-funded IT organization that provides member organizations with intrastate networking, virtualization and cloud computing solutions, advanced videoconferencing, connections to regional and international research networks and the commodity Internet, colocation services and emergency web-hosting.
The OARnet network (known for a time as Third Frontier Network and later, OSCnet) is a dedicated, statewide, high-speed fiber-optic network that serves Ohio K-12 schools, college and university campuses, academic medical centers, public broadcasting stations and state and local/state government. OARnet is considered[ by whom? ] one of the most advanced statewide telecommunications networks dedicated to research, education and economic competitiveness in the nation. [1]
OARnet is connected in Cleveland and Cincinnati to Internet2, the United States' most advanced nationwide research and education network. OARnet also maintains direct connections to Michigan's Merit network and OmniPoP in Chicago.
OARnet offices are located on the West Campus of Ohio State University in Columbus, Ohio, United States.
OARnet additionally serves as the delegated registrar for many third-level domains (both generic and locality-based) under .oh.us and some under .in.us and .ky.us. [2]
A member-organization of the Ohio Technology Consortium, [3] the technology and information division of the Ohio Board of Regents (now the Ohio Department of Higher Education), OARnet was created by the Ohio General Assembly in 1987 to provide Ohio researchers with network connectivity to the resources of the Ohio Supercomputer Center (OSC). It was recognized at the time that the network would serve a much broader audience, so when a network name was selected in early 1988, OARnet was chosen to emphasize the many uses of the network.
The initial plan (1987) was to make use of a number of existing Bitnet and CCnet (regional DECnet network) connections to get started. Three network (compatible) protocols were used, NJE, DECnet, and TCP/IP. The first OARnet-funded line was installed between Case Western Reserve University and John Carroll University in June 1987. Many subsequent lines at 9.6 kbit/s, 56 kbit/s, and T1 (1.544 Mbit/s) were installed with the aid of an Ohio Department of Administrative Services contract with Litel Corp. Internet (then NSFNET) connections were obtained in the spring of 1988. The non-TCP/IP protocols were soon phased out, and a process of upgrading connections took place regularly.
In 1991, it was decided that OARnet would accept commercial business, at appropriate rates, for Internet connection services. Thus OARnet became one of the first Internet service providers (ISPs) in Ohio. After commercial ISPs entered the business extensively, OARnet stopped seeking new commercial accounts.
A very large increase in backbone capacity occurred (planning 2000-02, installation 2003-04) when it became possible to lease optical fiber lines themselves ("dark fiber"). A new network backbone of 1,850 miles was installed at much higher capacity, and the eTech Ohio Commission and the Ohio Department of Education joined in funding and using OARnet. The fiber-optic backbone was launched in November 2004.
In 2006, OARnet provided one of the first networks for delivery of live TV via Internet Protocol, known today as IPTV. OARnet served as the backbone for Ohio News Network to transmit Miami Redhawks hockey. [4] The team finished the 2008-2009 season at the Frozen Four with a 4-3 OT loss to Boston University in the championship. It was one of the first live sports transmission delivery over IPTV in the US.
Another sharp jump in capacity occurred in 2012, when the State of Ohio funded an upgrade [5] of the OARnet backbone to 100 Gigabits per second. Today, more than 1,500 miles of Ohio’s network backbone runs at an ultra-fast 100 Gbit/s, which was recognized by ComputerWorld [6] in the Emerging Technology category of their 2013 Computerworld Honors Laureates program. In Nov. 2012, Case Western Reserve University became the first member institution to connect at 100 Gbit/s to the OARnet backbone. [7]
The OARnet leaders have been:
Janet is a high-speed network for the UK research and education community provided by Jisc, a not-for-profit company set up to provide computing support for education. It serves 18 million users and is the busiest National Research and Education Network in Europe by volume of data carried. Previously, Janet was a private, UK-government funded organisation, which provided the JANET computer network and related collaborative services to UK research and education.
A wide area network (WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits.
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.
Internet access is a facility or service that provides connectivity for a computer, a computer network, or other network device to the Internet, and for individuals or organizations to access or use applications such as email and the World Wide Web. Internet access is offered for sale by an international hierarchy of Internet service providers (ISPs) using various networking technologies. At the retail level, many organizations, including municipal entities, also provide cost-free access to the general public.
A leased line is a private telecommunications circuit between two or more locations provided according to a commercial contract. It is sometimes also known as a private circuit, and as a data line in the UK. Typically, leased lines are used by businesses to connect geographically distant offices.
CARNET is the national research and education network of Croatia. It is funded from the government budget and it operates from offices in Zagreb and five other cities.
AARNet provides Internet services to the Australian education and research communities and their research partners.
FUNET is the Finnish University and Research Network, a backbone network providing Internet connections for Finnish universities and polytechnics as well as other research facilities. It is governed by the state-owned CSC – IT Center for Science Ltd. The FUNET project started in December 1983 and soon gained international connectivity via EARN with DECnet as the dominant protocol. FUNET was connected to the greater Internet through NORDUnet in 1988. The FUNET FTP service went online in 1990, hosting the first versions of Linux in 1991.
Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.
The Corporation for Education Network Initiatives in California is a nonprofit corporation formed in 1997 to provide high-performance, high-bandwidth networking services to California universities and research institutions. Through this corporation, representatives from all of California's K-20 public education combine their networking resources toward the operation, deployment, and maintenance of the California Research and Education Network, or CalREN. Today, CalREN operates over 8,000 miles of fiber optic cable and serves more than 20 million users.
Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
SURF is an organization that develops, implements and maintains the national research and education network (NREN) of the Netherlands. It operates the national research network formally called SURFnet.
A core router is a router designed to operate in the Internet backbone, or core. To fulfill this role, a router must be able to support multiple telecommunications interfaces of the highest speed in use in the core Internet and must be able to forward IP packets at full speed on all of them. It must also support the routing protocols being used in the core. A core router is distinct from an edge router: edge routers sit at the edge of a backbone network and connect to core routers.
Internet access is widely available in New Zealand, with 94% of New Zealanders having access to the internet as of January 2021. It first became accessible to university students in the country in 1989. As of June 2018, there are 1,867,000 broadband connections, of which 1,524,000 are residential and 361,000 are business or government.
In an international context Denmark is viewed as a somewhat peculiar country when it comes to internet access. The former state owned telephone company TDC owns the entire last mile infrastructure in terms of copper telephone lines and the vast majority of the coaxial cable infrastructure as well. Even though the Danish telecommunications infrastructure is very heavily dominated by one company, Danish internet customers still enjoy fair prices and a wide availability of different next generation access internet connections in comparison with most other EU countries. Furthermore, TDCs de facto monopoly on last mile infrastructure has come under attack. In the last decade regional power companies have formed national business alliances aimed at implementing FTTH for private and business end users.
The prevalent means of connecting to the Internet in Germany is DSL, introduced by Deutsche Telekom in 1999. Other technologies such as Cable, FTTH and FTTB (fiber), Satellite, UMTS/HSDPA (mobile) and LTE are available as alternatives.
Gigabit wireless is the name given to wireless communication systems whose data transfer speeds reach or exceed one gigabit per second. Such speeds are achieved with complex modulations of the signal, such as quadrature amplitude modulation (QAM) or signals spanning many frequencies. When a signal spans many frequencies, physicists refer that a wide bandwidth signal. In the communication industry, many wireless internet service providers and cell phone companies deploy wireless radio frequency antennas to backhaul core networks, connect businesses, and even individual residential homes.
Merit Network, Inc., is a nonprofit member-governed organization providing high-performance computer networking and related services to educational, government, health care, and nonprofit organizations, primarily in Michigan. Created in 1966, Merit operates the longest running regional computer network in the United States.
ACOnet is the name of the national research and education network in Austria. The ACONET association promotes the development and use of that network. ACOnet is not managed and operated by ACONET, but by a unit in the Computing Centre of the University of Vienna that also operates the Vienna Internet Exchange. The University of Vienna represents ACOnet internationally, for example as a member of TERENA and as a participant in the project that funds the European backbone network GÉANT.
Missouri Research and Education Network (MOREnet) is a member-driven consortium, operating as a separate business unit within the University of Missouri in Columbia, Missouri. They are primarily made up of Missouri's K-12 schools, colleges and universities, public libraries and government organizations. In addition to maintaining a computer network for Internet access to school districts and libraries in the U.S. state of Missouri. they also provide technology consulting, a technology help desk as well as professional development and training, consortium discounts and a la carte services by a team of approximately 85 subject matter experts.
