Gigbit GigE GbE
Gigabit Ethernet, abbreviated GbE or GigE, is a version of Ethernet, which supports data transfer rates of 1 Gigabit (1,000 megabits) per second. Since its inception at Xerox Corporation in the early 1970s, Ethernet has been the dominant networking protocol. Of all current networking protocols, Ethernet has, by far, the highest number of installed ports and provides the greatest cost performance relative to Token Ring, Fiber Distributed Data Interface (FDDI), and ATM for desktop connectivity. Fast Ethernet, which increased Ethernet speed from 10 to 100 megabits per second (Mbps), provided a simple, cost-effective option for backbone and server connectivity.
Gigabit Ethernet builds on top of the Ethernet protocol, but increases speed tenfold over Fast Ethernet to 1000 Mbps, or 1 gigabit per second (Gbps). This protocol, which was standardized in June 1998, has become a dominant player in high-speed local area network backbones and server connectivity. Since Gigabit Ethernet significantly leverages on Ethernet, customers are able to leverage their existing knowledge base to manage and maintain gigabit networks.
Gigabit Ethernet (GigE) is now commonly used as a high-speed link between switches and servers. Ethernet devices negotiate with each other and transmit at the highest speed possible. However, if a 100 Mbps switch is communicating with a 10 Mbps client, the slower speed is used. There are two Gigabit Ethernet standards which describe Ethernet systems that operate at 1000 Mbps. The 802.3z standard describes the specifications for the 1000BASE-X fiber optic Gigabit Ethernet system. The 802.3ab standard describes the specifications for the 1000BASE-T twisted-pair Gigabit Ethernet system.
