IBM DatagLANce (TM) Network Analyzer
    for Ethernet and Token Ring




Accurate, affordable analysis power at your command!

-----------------------------------------------------------------------
Experience the difference for yourself.  No longer do you need to pay a
fortune for a cumbersome benchtop analyzer just to know that your data
is accurate and complete.  The DatagLANce Network Analyzer lets you see
what you want, the way you want to see it.  And you don't need
superhuman strength to carry this analyzer with you.  DatagLANce
software performs simultaneous Ethernet and token-ring analysis even in
a *laptop* computer.
-----------------------------------------------------------------------




LAN analyzers redefined
-----------------------

Let's face it.  Networks are growing and multiplying at an unprecedented
rate.  On top of that, they change from minute to minute.  Even if your
LAN works fine today, that's no guarantee for tomorrow.  And what about
performance?  Are you really utilizing your equipment to its maximum
potential, or should you upgrade?  DatagLANce unlocks the mystery behind
your network.  If you maintain, monitor, evaluate, or build LANs, the
DatagLANce Analyzer provides the edge you need to cope with these
challenges.

There's such a jungle of LAN analyzers out there today, why choose
DatagLANce?  The answer is simple.  DatagLANce delivers value.  For less
investment than you'd expect, you can have a state-of-the-art LAN
analyzer that's easy to learn, fun to use, unbelievably flexible, and
loaded with the right mix of rock-solid functions.

In fact, after you use DatagLANce, you may never feel the same way
toward *any* software program again.  The brilliant DatagLANce user
interface gives you not only extraordinary access to its dazzling array
of analysis functions, but also lets you sculpt your own interface with
point-and-click ease.  With DatagLANce you feel the exhilaration of
designing, preserving, and exploiting the screens that will best present
and navigate through your network.  There's no longer any need to remain
locked in the straitjacket of a single, fixed set of screens and
indicators.  And no longer must you settle for an out-of-date
character-mode display.

But DatagLANce offers much more than just a very pretty face.  Actually,
it's the underlying power beneath it that unleashes this beauty.
DatagLANce exploits the multitasking magic of the OS/2* operating system
to focus its power on your toughest problems.  Imagine what it would be
like to have a network analyzer so powerful that it could perform
simultaneous Ethernet and token-ring monitoring, analysis, *and
capturing* on a single laptop machine.  DatagLANce delivers that power
and more!

The secret of lost data--revealed
---------------------------------

The secret is out.  Thanks to an article in the January 1993 edition of
*Data Communications*, LAN analyzers now have to come clean.  What could
be worse than having a tool that doesn't work?  How about one whose
results may or may not be correct?  Listen to what the article has to
say:

     "The lab found that even under light loads (low frame rates),
      many analyzers cannot even accurately monitor traffic--the
      most basic analyzer function. Counts are often off 30 percent
      to 40 percent, or more.

      At higher frame rates, monitoring is grossly inaccurate, but
      none of the analyzers lets users know that LAN traffic is
      exceeding their limits . . .

      To add insult to injury, the test lab pointed out the very
      same problems more than a year ago . . ."

How can this be?  All but the most hardware-intensive LAN analyzers
(DatagLANce included) rely on the host computer and adapter card to
supply the data-gathering horsepower to do the job.  When the data rate
being monitored outstrips the power of the hardware, frames will be
missed.  *Data Communications* points out that this problem is "all too
often aggravated by poorly written code."

But we can't *advertise* that we are losing frames, can we?  The
customer might think that we are offering an inferior
product--especially if we display it on the screen.  Unfortunately, too
many analyzers would rather ignore the truth than face it.

With DatagLANce, you need not wonder about your data.  Admittedly, given
enough traffic, even DatagLANce can miss frames, but DatagLANce
performance rivals the best software-based analyzers around.  This is
because it leaves the high-speed data gathering job to tightly-written
code located very close to the hardware, deep in the device driver.
There's no sloppy code here.  However, when frames are being dropped,
the DatagLANce Analyzer makes sure you know: first, with a pop-up window
alert, second with a status indicator, and finally in the capture data
itself.  In addition, DatagLANce offers a number of options (selectable
from a simple menu) for slicing data, and selecting priorities to
minimize the possibility that you will ever miss what you really need to
see.

Energize your computer
----------------------

Personal computers are getting faster and more powerful every day.  Yet
so much of that potential power sits untapped and unused.  Bigger
memory, faster and wider processors, larger displays, and denser disks
usually sit idle or are wasted on frills and bloated code.  Wouldn't it
be nice to multiply your effectiveness by taking full advantage of your
valuable resource?  If you're a power user who yearns to utilize your
computer to its fullest, DatagLANce is for you.

Look carefully at any of the screen pictures in this brochure.  Notice
how each contains multiple windows.  DatagLANce calls each group of
windows a *screen*.  Depending upon your display resolution (and your
eyesight) you can select the number of windows (up to 32) and the
window/font size to arrange the optimum amount of information on each
screen.  Once you define a screen, simply give it a name, and you can
return to it easily from the *Screen* pull-down menu.

If you have lots of memory, DatagLANce can ignite it into action.  Give
some to your operating system to speed task switching.  Then allocate
whatever remaining amount you like to the high-speed capture buffer.
And since (unlike most other analyzers) DatagLANce can capture to disk
as well as to memory, use some of your hard drive for a disk capture
buffer.

But wht about the processor itself?  For starters launch Ethernet,
token-ring, and multiple protocol analysis sessions.  Open the online
*DatagLANce User's Guide* and discover the next treasure you can
uncover.  Have each analyzer session monitor alarm conditions, display
network statistics, accumulate traffic matrix statistics, capture
filtered traffic, and record history statistics to a file--ALL IN REAL
TIME.  Since DatagLANce does most of the work for you, you still have
time to open up your spreadsheet, mail program, or word processor and
get even more work done.  The nice thing about DatagLANce is that it's
totally scalable--ready to adjust to your changing needs and hardware.

Your amazing private interpreter
--------------------------------

Imagine what it would be like to travel the world with a friend who knew
over a hundred different languages and customs.  In the LAN world,
DatagLANce is that companion.  It's no secret that lots of analyzers
claim to "support" a wide range of protocols--but watch out.  Some make
the claim if they *recognize* or *partially interpret* the language.
There is a vast difference between being able to say "That's German and
that's Italian" or even being able to recognize a simple greeting versus
full support of a language.  What would you rather hear from your
interpreter?  "That's Russian" or "Look out, you are about to be run
over by a truck!"

We admit it.  A *few* analyzers do exist that support more protocols
than DatagLANce does presently, but the difference is really not worth
considering.  Why?  Because the DatagLANce development team has listened
to customers and focused design effort on the most popular protocols
first.  Odds are, DatagLANce supports everything you need right now, but
if not, let us know.  Remember, when you buy your DatagLANce you get one
full year of free protocol upgrades.  Even if you have a present need
for an unsupported protocol, the raw power of the DatagLANce filters and
unmatched ease of presentation will go a long way towards getting you in
touch with your data.

Precision capture
-----------------

Even with the best protocol decoder, a network analyzer has very little
value if it can't effectively capture, locate, and present the data you
need to see.  In each of these areas, the DatagLANce Analyzer more than
meets the challenge.  The DatagLANce architects learned their lesson
well in designing the Professional DatagLANce Analyzer for FDDI.  With a
network speed about ten times faster, the FDDI analyzer stores massive
amounts of data in an instant.  To deal with the problem of sorting
through the data, DatagLANce offers real-time filters and event
detectors to pinpoint start and stop times for capture, determine the
amount of data that surrounds a key event, and select the types of data
to be saved.  DatagLANce even lets you glance at data being captured
without disturbing the process.

DatagLANce gives you eight exceptionally powerful event detectors each
programmable to recognize up to 48 different protocols, detect up to 11
address pairs, or search for a data pattern either throughout each frame
or a fixed offset from the beginning.  They even optionally ignore
source routing information.  You can then combine event detectors using
logic equations to activate capture options and drive up to five custom
counters for storing and displaying statistics tailored exactly to your
needs.

When you're ready for analysis, eight more event detectors await your
command.  That way, you have a choice: capture everything and filter
during analysis, or reduce the data volume up front by carefully
selecting what you capture.  And with the new quick filter, you select
search addresses as easily as pointing to the address you see in your
data and clicking on it.  You can further slice your way through
captured data with bookmarks, text search, and scrolling functions.
Note also that the DatagLANce software values your time.  Even in large
files, once your data has been located, DatagLANce can return there with
minimum delay.

Point-and-click ease transports you instantly to three different levels
of detail of your data.  With full-color coding and fully adjustable
fonts, the protocol analysis screen leaps into action.  Take the wide
view with the one-frame-per-line summary display.  Select types of
addresses, time stamps, protocol summaries, and counts you need to see.
Then just click on a line to reveal the remarkably detailed picture
DatagLANce gives you to explain what it all means.  Both troubleshooters
and application programmers will appreciate this widespread support of
decoding all the way up the seven-layer model.  Finally, click on a line
of detail and see, in both hexadecimal and character views, the raw data
being interpreted--all color coded and tracking in lock-step with the
other screens.  Even if you need to analyze data captured by another
popular analyzer, DatagLANce will present it like you've never seen it
before.

Information overload
--------------------

That's right.  It's worse than being in the cockpit of a jumbo jet.
There's just more network information out there than one person can sort
out.  How can you possibly keep up?  Easy.  Let DatagLANce do most of
the work for you with five-level alarms, traffic statistics, ring map,
and dynamic statistics displays.  Take your pick.  Accumulate statistics
to a file for later analysis with your favorite spreadsheet, or select
data to display.  Choose bar chart, history graph, or numeric formats.
Utilize your event detectors and five custom event counters to show you
exactly what you need to see.

The incredible flexibility of DatagLANce almost defies
description--especially when it comes to explaining all the
possibilities for displaying statistics and status information.  Rather
than try, let's just look at a few examples of things DatagLANce will
present.  Of course, you can see network speed, utilization, times
active, error types, and data rates, but that's just a start.  Capture
status and ring map information are yours for the asking.  Choose a
traffic analysis window to reveal dynamic sorts of top talkers,
listeners, error makers, major protocols, and minor protocols.  If you
wish, select protocol distribution, frame size distribution, or source
routing type distribution from a myriad of predefined icons.  Even save
your own custom configurations and define an icon for each of them.  The
possibilities are virtually endless.

Transport your vision
---------------------

Whether across the hall or around the world, take command of an arsenal
of DatagLANce Analyzers right from your office.  Thanks to the optional
application IBM Distributed Console Access Facility (DCAF) Version 1.1
you can take full control of multiple DatagLANce analyzers from a single
workstation.  Whether you choose modem or LAN communication , DCAF can
deliver you crisp, fluid control of all the action.  Just have your
DatagLANce connected to the LANs you want to see, and your networking
experts, wherever they may be, can tune in and take charge.

Word of mouth
-------------

You've heard it before.  The best advertising comes from satisfied
customers.  To assure high quality, we offer and test DatagLANce
products inside IBM before we offer them to the general market.  Here's
just a sample of responses we've received from internal IBM customers:

    "This product is good stuff.  Our development team wants to use this
    rather than the . . . tool we had before.  It does more and our team
    likes it better."

    "I took a gamble when I did the engagement.  I had LCON with me for
    backup but I used the beta code for DatagLANce that has the matrix
    option incorporated.  I really like DatagLANce.  The product worked
    flawlessly (as far as I can tell).  The protocol detail was excellent.
    I didn't lose any frames even using a P75 with a TAP adapter and an
    Ethernet Adapter/2.  I ran both the Ethernet and token-ring versions of
    DatagLANce without any problems."

    "I'm recommending to my management that we use DatagLANce instead
    of . . . or . . .  It's easy to use, OS/2 based.  I can monitor
    and collect matrix data simultaneously.  The monitor is a good way to
    see utilization spikes that may be hiding in a relatively low average
    utilization number."

    "It can capture as well as monitor and matrix.  You can customize and
    save configurations to monitor for specific symptoms.  It's totally
    GUI-driven.  You might think I like DatagLANce.  I DO!"

Still not convinced?
--------------------

As you can probably tell, DatagLANce is the answer to today's tough LAN
analysis problems.  But if you're still not sure, you don't have to take
our word for it.  Why not try DatagLANce for yourself?  Before you risk
thousands of dollars on some other analyzer that might disappoint you,
get a copy of the brand new DatagLANce working demo.  Load it into a
compatible computer and experience for yourself the magic and thrill of
DatagLANce in action.
