Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet, which
utilizes the same packet structure, format, CSMA/CD protocol, full
duplex, flow control, and management objects. From the bandwidth
point of view, Gigabit Ethernet has a tenfold increase in theoretical
throughput over 100Mbps Fast Ethernet and a hundredfold increase
over 10Mbps Ethernet. Since it is also compatible with 10Mbps and
100Mbps Ethernet environments, Gigabit Ethernet provides a
straightforward upgrade without wasting a company's existing
investment in hardware, software, and trained personnel.
The higher packet transfer speed and extra bandwidth offered by
Gigabit Ethernet is essential when coping with the network
bottlenecks that frequently developed as the computers and their
busses get faster and more users use applications that generate more
traffic. Upgrading key components, such as your backbone and
servers to Gigabit Ethernet can greatly improve network response
times as well as significantly speed up the traffic between your
subnets.
Fiber Gigabit Ethernet enables Fiber cable connections to
support video conferencing, complex imaging, and similar
data-intensive applications. Likewise, since data transfers
occur 10 times faster than Fast Ethernet, servers outfitted
with Gigabit Ethernet NIC's are able to perform 10 times the
number of operations in the same amount of time.
