	BBC News \| Sci/Tech \| Gigabit per second delivered to desktop
		Transferring a billion bits per second would mean, for example, that watching real-time high-quality video would be routine.
		Gigabit networks and network cards can be bought now but do not function at these speeds.
		The backbones of current LANs can run at a gigabit per second but the data transfer to a desktop computer connected to the LAN is limited by the network card, usually 10 or 100 megabits per second.

	HPCC Insights - Ultra fast gigabit networking
		Gigabit networking applications within NASA will include rapid data transfer in everything from research and development and space missions to public outreach and educational activities, according to Marjory Johnson, NREN associate project manager.
		As a multitude of uses for gigabit networking are being identified, the NREN team -- as with other groups -- is working to fine-tune the technology, as well as to demonstrate its capabilities, according to Johnson.
		Gigabit networking, then, offers the capability of moving a billion bits of data per second -- many times faster than the computer networks that most people are currently familiar with.

	Intel Corporation
		Gigabit Ethernet was the latest innovation in high-speed network technologies and was predicted to enjoy phenomenal growth rates and wide spread acceptance over the next several years.
		Gigabit Ethernet could transfer information from computer to computer at an alarming 1,000 Mega-bits per second (Mbps) (1 gigabit per second), thereby increasing the speed of a 10Mbps or 100Mbps network by a factor of 100 or 10 respectively.
		Gigabit Ethernet used many of the same technical standards as previous Ethernet versions, and therefore, Intel believed, represented the most logical and appropriate solution for upgrading the network.

	Review: Gigabit Network Combo
		Consumer gigabit Ethernet is young enough that the chipset used by your NIC is something to which you should pay attention, if you're not a Windows user.
		Gigabit may help considerably if, when multiple terminals try to update at once, everything suddenly runs like a Kombi van full of Presidential bodyguards going up a steep grade in fourth gear.
		Gigabit's also likely to be ever so handy if you're interested in building a supercomputer in your garage.

	2.2 Gigabit Ethernet Technology
		It offers one gigabit per second (1 Gbps) raw bandwidth which is 10 times faster than fast Ethernet and 100 times the speed of regular Ethernet.
		When Gigabit Ethernet operates in full duplex mode, it uses buffers to store incoming and outgoing data frames until the MAC layer has time to pass them higher up the legacy protocol stacks.
		Gigabit Ethernet is most effective when running in the full-duplex, point-to-point mode where full bandwidth is dedicated between the two end-nodes.

	Military & Aerospace Electronics - Experimental VME backplane databus can move data at 1 gigabit per second
		Computer scientists are on the verge of boosting VME backplane databus speeds to as fast as 1 gigabit per second, or to enable a larger number of backplane slots to function at the same speed without incurring any substantial cost penalty, officials of VITA, the open-standards organization in Scottsdale, Ariz., announced today.
		Inventor Andrew Berding, creator of the VME 320 standard, has invented a way to create a backplane where driver signals are independent of their backplane slots to create more robust VME signals than ever before to speed backplane data throughput.
		The second option might be attractive for a VME backplane that now is limited to 21 slots in a 19-inch relay rack, Berding says.

	Towards Gigabit Networking
		While there is nothing inherently "gigabit" about multimedia (we've got cruddy multimedia on the Internet now), the advent of the broadband network infrastructure will enable the wide scale deployment of a number of new applications (including multimedia) to a degree not possible before.
		Gigabit bandwidth to the application is simply a matter of economics; when it is cheap enough, it will be widely deployed.
		This requires Gigabit IP routers in the backbone network, and such projects are underway (the Washington University project uses an ATM switch as the core of the IP router).

	Ethernet speeds raised to 100 gigabits per second - Engadget
		Our consumer-grade home DSL is starting to look pretty paltry compared to the records that are coming out of research labs these days.
		Yea, this is the second time in a week that Engadget uses the word "IEEE" and proves that they have no clue whatsoever about how the IEEE works.
		Sure, if the majority of consumers were willing to spend $10,000 per month on bandwith I would also conclude we would get what we want, but that is a rational conclusion to draw upon.

	Technology Review: Intel Speeds Up Silicon Photonics
		The team has demonstrated a record-breaking silicon modulator that can encode data at a rate of 30 gigabits per second--nearly as fast as many nonsilicon modulators currently used in fiber optics hardware.
		In 2005, they increased its speed to 10 gigabits per second and built a surprisingly good silicon laser (see "Intel's Breakthrough").
		Today's state-of-the-art modulators work at 40 gigabits per second, and for silicon to compete as an optical material, it needs to operate at comparable speeds.
