Explanation of Gigabit over Cooper
...Before 1000Base-T, gigabit Ethernet required using either
fiber-optic or special shielded copper cables, neither of which was practical
for everyday LAN construction. These versions (1000Base-SX, 1000Base-LX, and
1000Base-CX) are still in use today in specialized applications, but we won't be
focusing on them in this NTK.
The 802.3z Gigabit Ethernet task force did its work well, and
was able to come up with a standard that is, for all intents and purposes, a ten
times faster version of 100Base-T. 1000Base-T was also designed so that it is
backwards compatible with 10/100 equipment, and uses CAT-5 (or
better) wiring (the stuff that you're using for your current LAN)...
...As I briefly mentioned in the Introduction, one of the key
requirements for the 1000Base-T standard is that it work with existing
Category 5 (CAT 5) cabling. After all, what good is a copper-over-Ethernet
standard if it can't run on most of the copper that's already in the walls,
network closets, and ceilings of corporate America? So the good news is that,
unless your network was installed in 1996 or earlier (the standard was revised
in 1995), you're probably ready to rock when you decide it's time to move up to
gigabit speeds.
But before you move on to the next section, there are
some issues that you need to be aware of:
-
Four Pairs Required: As this
article shows, 1000Base-T uses all four twisted pairs of the
Category 5 (or higher) cable to create four 250Mbps channels. (A different
encoding scheme -- five level PAM -- is also used so that the signals stay
within the 100MHz bandwidth rating of CAT 5 cabling.) These two features
result in the ability to achieve full gigabit bandwidth while using existing
CAT 5 cabling.
-
No Bad Crimps and No Cheap Jacks: Another problem
that do-it-yourself cablers may find is that poor crimps and inexpensive wall
jacks can lower the maximum achievable bandwidth of their gigabit networks.
These issues can cause impedance mismatches, which cause return loss, which
can cause lower bandwidth. Although you can try "shotgunning" (blindly
changing things) if you run into bandwidth problems, you'll need to either
have a qualified network installer test your network for return loss and
crosstalk to qualify it for gigabit operation, or just live with the lower
speed.
-
Length and Topology Limitations: 1000Base-T is
limited to the same 100-meter maximum length as 10/100Base-T. This rule also
means that there is a 200-meter maximum distance (network diameter) from one
computer to another that is connected to the same switch. In general,
1000Base-T network topology rules are the same as for 100Base-T, except that
only one repeater is allowed per LAN segment (or, to be more exact, per
"half-duplex collision domain"). But since gigabit Ethernet products don't
support half-duplex operation, the last point can safely be ignored.
Basically, if your LAN is working with 100Base-T, you shouldn't have to
rearrange things for gigabit operation.
For new network installations, the general recommendation is
to use CAT 5e cable. Although CAT 5 and CAT 5e cabling both have
100MHz bandwidth, CAT 5e cable is manufactured so that additional parameters
that are important for high frequency data signals are better controlled...
...One thing you shouldn't buy into, however, is any
recommendation that tells you to use CAT 6 for a gigabit Ethernet
installation. CAT 6 was
added to the TIA-568 standard in June 2002, and has a 200MHz
bandwidth. Despite the fact that vendors would love to sell you their pricier
CAT 6 wares, you should only consider it if you're going to be running
10Gigabit Ethernet over copper, which, frankly, any small networker is going
to be extremely unlikely to do! And pitches for CAT 7 cable? Fuggedaboutit!
...Since all you'll need to buy are Network Interface Cards (NICs)
and a gigabit switch, let's see what that'll run you:
-
NICs: Name-brand 32bit PCI 10/100/1000Base-T NICs
such as Intel's PRO1000 MT, Netgear's GA302T, and SMC's SMC9552TX can be found
online for prices ranging from US$40 - US$70. Products from second-tier
manufacturers may be able to save you another US$5 or so. Although about two
and a half times the price of the average name brand 10/100 NIC, unless you're
buying a bunch, this price won't break the bank.
You can also find NICs that can handle both 32 and 64 bit
PCI, but they'll cost you more. What you won't find, however, are CardBus
adapters for your laptop or notebook. For some reason, manufacturers seem to
think that notebook users neither need nor want gigabit connectivity!
-
Switches: The price tags for 10/100/1000 switches
are more likely to make would-be gigabit upgraders think twice before plunking
down their money. But the good news is that simpler, unmanaged gigabit
switches are now available, and the cost savings over managed enterprise-grade
equipment is significant.
Netgear's GS104 basic four-port 10/100/1000 switch can be
found for less than US$225. If you expand your search beyond the more
recognizable names, you'll find even lower prices, such as TRENDnet's
TEG-S40TXE for about US$150. If you need more than four ports, you can bump up
to the eight-port versions, namely Netgear's GS108 (about US$450) or
TRENDnet's TEG-S80TXD (about US$280).
Considering that you can pick up a five-port 10/100 switch
for as little as US$20, the above prices might be considered too steep for
some. But considering that not long ago you could purchase only managed
gigabit switches at US$100+ per port, the above prices show that the trend is
heading in the right direction!
The dirty little secret of gigabit Ethernet is that if you're
running Win98 or 98SE, you probably won't get any benefit from your investment
in gigabit gear. Although there are some registry edits that you can try to
improve your throughput, you probably won't see much improvement over the
network performance you're getting now with 10/100 equipment.
The problem is that the TCP/IP "stack" in Win98 really wasn't
designed with such high speed networking technology in mind, and has a hard time
using a 100Base-T connection at its full potential, let alone a gigabit
link! I'll have more on this topic in Part 2 of this NTK, but in the meantime,
consider Win2000 and WinXP as the only serious Windows OSes to use
for gigabit LANs.

Windows Longhorn Leak Offers Peek at
Future
By Nate Mook
An
internal alpha build of Microsoft's next Windows release, code-named Longhorn,
has slipped out of Redmond labs for the second time in four months.
...Longhorn's "Plex" visual style (screenshot)
has been slightly polished, sporting new graphics for buttons and tabs.
...But a look beneath the surface reveals that build 4008 contains more than
simple tweaks, and hints at what the future of Windows may hold.
Microsoft has finally replaced the text-based Windows installation with an
entirely graphical setup. In order to achieve this, Longhorn makes use of the
Windows Preinstallation Environment.
WinPE is a small operating system that sits on the Longhorn CD and contains
the minimum functionality needed to install Windows.
...Beginning to emerge in build 4008 are services based on Windows Future
Storage – the new file system built upon next-generation SQL technology
code-named Yukon. With WinFS and Yukon, Microsoft aims to abstract the
user from the data storage process, making the physical location of a file
irrelevant. The file system will instead work like a SQL database and reference
files as they are needed for certain tasks.
...Rather than opening a
specific folder as in Windows XP, My Pictures (screenshot)
and My Music (screenshot)
in Longhorn bring up "virtual folders" that display appropriate files indexed
from various physical locations. Although pictures and music may be spread out
across multiple folders or drives, they can be accessed using a single interface
(screenshot).
Such a system has numerous advantages for transparently organizing media or
documents. For example, Longhorn creates a virtual folder hierarchy using file
attributes such as image date, or composer of a song. A user can customize the
view and effortlessly retrieve specific files that match certain criteria.
Longhorn also has the ability to "stack" (screenshot)
files into groups. Stacking files creates pseudo-directories namely to simplify
organization of documents.
...With a focus shift away from file location, Microsoft is phasing out the
address bar with what it calls a "breadcrumb bar." The breadcrumb bar covers the
address bar in Explorer and creates a button for each window opened. A user can
instantly jump back to previous windows or perform a task within that window
using the breadcrumb dropdown menu.
...Although notable progress is being made in its alpha stage, Longhorn is not
expected to hit beta for months and any current plans or features could
drastically change as development progresses. Microsoft has not announced a
release timeframe, but Longhorn is expected to be complete by late 2004 or early
2005...

Microsoft Ups Ante in Instant Messenger Battle
By
Jim Hu
Microsoft on
Thursday plans to launch a trial version of its instant messaging software for
corporations, upping the ante in the battle for supremacy over one of the
world's fastest growing communications technologies.
Dubbed Greenwich, Microsoft's
new server software allows businesses to support secure instant messaging on a
network. In addition, it offers a bridge to Microsoft's popular consumer MSN
Messenger IM network, giving it a potential jump on rivals lining up to court
business customers with instant messaging products and services.
"IM is a very hot subject right
now among corporate users trying to tame this technology that has found its way
into IT environments without, necessarily, IT approval," said Michael Gartenberg,
an analyst at Jupiter Research.
...America Online, Yahoo and
Microsoft... have been prepping their popular consumer IM products with new
features such as security and authentication to compete with rivals that were
quicker to court business customers. But some significant hang-ups continue to
stall widespread adoption in the workplace, including a lack of interoperability
between the three leading IM networks.
With its heavy presence in both
the consumer and corporate markets, Microsoft holds some unique advantages that
could help it bridge the gap between the two.
...Greenwich is expected to
officially launch in the "middle of this year," according to a company
representative. Although Microsoft was originally planning to
integrate Greenwich into Windows .Net Server 2003, Singh Pall said the
company may sell it individually, although no decisions have been made yet.
The beta version of the
software will include real-time communication features beyond instant messaging,
such as presence and multi-party collaboration. The software will also include
multimedia functions such as PC-to-PC voice and video transmission...

ATI Radeon 9800, 9600 and 9200 Series
...ATi is
updating its entire product line. All cards of the 9000, 9500, and 9700 series
will be replaced by successors named 9200, 9600, and 9800, respectively.
The new Radeon 9800 DirectX 9 VPU (R350) supersedes the
highly successful Radeon 9700 (R300). Technologically, the chip is an updated
and optimized R300 core, with changes that go beyond a simple clock speed bump.
The shader unit (SmartShader) has been supplemented with a so-called "F-Buffer",
which theoretically allows shader code of infinite length. As a dig at NVIDIA
for calling the FX a "DirectX 9+" part because of its extended programmability,
ATi has named their R350 a "DirectX 9++" part. You've got to love that
creativity.
....The Radeon 9800 PRO makes an impressive showing,
nullifying the slim lead NVIDIA's FX 5800 Ultra held over the Radeon 9700 PRO.
While the newcomer achieves parity with the NVIDIA card in standard tests, it
totally dominates the FX 5800 Ultra when it comes to FSAA and anisotropic
filtering. Additionally, the ATi cards offer the better FSAA/aniso
implementation in our comparison. It remains to be seen whether this will change
with future driver updates from NVIDIA. We'll take a closer look at image
quality on both cards as soon as we have WHQL (or final) drivers for these
cards.
In addition to its more compact design (single-slot solution)
and its simpler (and much quieter) cooler, the Radeon 9800 PRO is also much
faster than the FX 5800 Ultra in all important disciplines (FSAA, anisotropic
filtering) and offers the best image quali ty
with those features enabled. If you're looking for the fastest 3D accelerator
currently available, the Radeon 9800 PRO is your chip. This doesn't make the
GeForce FX 5800 Ultra a bad product by any means, but the leadership is once
again firmly in ATi's hands.
We'd be harder pressed to make any recommendations on the
Radeon 9500's successor, the 9600 PRO. Judging from the specs, it looks like the
4x1 design will probably be slower than the older 9500 with its 8x1 design,
despite the clockspeed advantage (400MHz vs. 275MHz). We will only be able to
answer that conclusively once we have a review sample, though.
Don't hold your breath for any surprises where the Radeon
9200 is concerned though. This chip offers nothing new over its predecessor,
aside from an AGP8x interface...

Sony Unveils First Blue-Laser DVD Recorder
Japan's Sony Corp said on
Monday it would start sales next month of the world's first DVD recorder that
uses blue laser light and can pack a two-hour high-definition TV program onto a
single disc. It won't be cheap, with a retail list price of 450,000 yen
(US$3,800) while low-end DVD recorders using conventional red lasers go for as
little as US$200.
...The recorder, which includes
a built-in broadcast satellite tuner, will hit store shelves in Japan on April
10. No date has been set yet for an overseas roll-out...
...Blue light, with a shorter
wavelength than red, can read and store data at much higher densities needed for
high-definition recordings.
Blu-ray discs, which Sony will
also start selling on April 10, hold up to 23 gigabytes of data, or nearly five
times as much as existing DVDs and enough for two hours of digital satellite
high-definition programming.
At 3,500 yen each, Blu-ray
discs will also cost several times more than conventional discs.
Other members of the Blu-ray
consortium include Matsushita Electric Industrial Co which makes Panasonic
products, South Korea's Samsung Electronics Co Ltd and Dutch manufacturer
Philips Electronics NV.
Toshiba Corp, a pioneer in DVD
technology, has weighed in with a competing blue-laser format it says will be
less expensive and more compatible with existing recorders, although it would
only store 15-20 gigabytes of data per disc.
A fragmentation of recording
formats for existing red laser products has been blamed for hindering a take-off
in DVD recorder sales, although the market has begun growing rapidly as the
machines get cheaper.
Sony's Blu-ray machine will be
able to play red-laser discs using the DVD-R and DVD-RW formats, but not those
using the DVD-RAM or DVD+RW formats.
Toshiba is hoping to have its
first blue-laser DVD recorder on the market in another year or so, a spokesman
said, although an industry body is still hammering out technical details for the
format.

New Office Beta to Launch Next Week as Office 2000 Continues to Gain Market
Share
By Joe Wilcox
Microsoft plans to officially
launch Office 2003 Beta 2 on Monday, a release that will include a public
preview available to several hundred thousand beta testers and businesses, said
sources. ...In the most recent quarter... Office accounted for $2.4
billion of the company's $8.5 billion in revenue, and $1.88 billion of the $3.25
billion gross profit.
...People signing up for the
public preview are expected to pay for shipping. In the past, Microsoft has
offered public previews for free but charged between $20 to $30 for shipping and
handling.
...In terms of the number of
products being tested, the new Office 2003 beta will be one of Microsoft's
largest. Besides Office 2003 Professional, which includes Word, Excel, Outlook,
PowerPoint and Access, Microsoft also will offer betas of the FrontPage Web site
creation and management application, InfoPath, OneNote, Outlook with Business
Contact Manager, Publisher, SharePoint Portal Server and SharePoint Services.
...Another new product, code
named Iris, will be Outlook 2003 with Business Contact Manager. Like OneNote and
InfoPath, Iris reached only a small number of testers during Beta 1. The new
version of Outlook
will add customer relationship management (CRM) features that could appeal
to small- and medium-sized businesses.
...In general, Outlook is the
most overhauled application in the new Office suite. Microsoft has moved the
preview pane from the bottom of the screen to the right, so messages appear like
full-page documents. The company also scrapped the Outlook Bar (YAAA... I
hate that Damn thing and always turn it off) and beefed up security
features.
..."Microsoft needs to find
more ways to increase the appeal of Office," Silver said. Microsoft's biggest
competitor is "older versions of Office." In fact, Office 2000 gained market
share last year, he said.
