| Abilene |
Abilene is an Internet2 backbone network. Internet2 and Abilene are the two principal projects of UCAID. |
| bandwidth |
The amount of data that can be transmitted over a network in a fixed amount of time. Bandwidth is the fundamental networking
parameter, and is usually measured in kilobits, megabits or gigabits per second (kbps, Mbps, or Gbps).
|
| Dark Fiber Initiative |
The Third Frontier Network (previously known as the Ohio Dark Fiber Initiative) is being created to provide advanced telecommunications
services to support higher education and research in the state of Ohio. The goal of this project is to create a premier network
that will enhance research, education, and economic development that will help expand Ohio¹s role and reputation in networking
technology.
|
| delay |
How long it takes a packet to travel from its source to its destination. Also called latency. |
| gigaPop |
Gigabit point of presence - a regional internetworking aggregation point. |
| H.323 |
A set of ITU standards for Internet videoconferencing and VoIP. |
| Internet2 |
A university-led effort to develop advanced network applications and the network technologies needed to support them. The
200+ U.S. universities that lead the project work closely with partners in industry and government, and with advanced networks
around the world. "Internet2" is a registered trademark.
|
| iPv6 |
Internet Protocol version 6 - The next version of the Internet Protocol. The current version is IPv4; IPv5 was an experimental
real-time streaming protocol. IPv6 offers several improvements over IPv4, including a vastly larger address space.
|
| latency |
How long it takes a packet to travel from its source to its destination. Also called delay. |
| middleware |
Roughly, a layer of software between the network and the applications; middleware is also known as "glue". Middleware is notoriously
hard to define. One of the most popular definitions is "the intersection of what network designers and application developers
each do not want to do."
|
| multicast |
A set of technologies that make efficient one-to-many and many-to-many real-time communication possible on the network. |
| NGI |
Next Generation Internet - A now-concluded Federal program focused on developing advanced applications and networking capabilities
needed by US Goernment agencies such as NASA and the DOE.
|
| OARnet |
Ohio Acadmic Resources Network |
| OC-3 |
Short for Optical Carrier, used to specify the speed of fiber optic networks conforming to the SONET standard. An OC-3 = 155.52
Mbps.
|
| packet |
A message transmitted over a network. Large chunks of information are broken up into packets before they are sent across the
Internet.
|
| QoS |
Quality of Service - a network's ability to give different treatment to traffic from different users or applications. Today's
Internet does not offer QoS. QoS is specified in terms of one or more of the following parameters: bandwidth, delay, jitter,
and loss.
|
| SONET |
Short for Synchronous Optical Network, a standard for connecting fiber-optic transmission systems. |
| Third Frontier Network |
The Third Frontier Network (previously known as the Ohio Dark Fiber Initiative) is being created to provide advanced telecommunications
services to support higher education and research in the state of Ohio. The goal of this project is to create a premier network
that will enhance research, education, and economic development that will help expand Ohio¹s role and reputation in networking

| UCAID |
University Corporation for Advanced Internet Development - The nonprofit corporation that oversees the Internet2 and Abilene
projects.
|
| VoIP |
Voice over IP |
