| 1.0.- Windows Network
Modeling - An introduction |
| |
| Windows... who doesn't talk bad about Windows
at least once in his/her live? But all of us have to admit that
software available for this ubiquitous operating system is really
unbeatable. And we have to admit too that last Windows generation is
really very good. XP™ is a very mature operating system and being not
sectarian we have to admit it. |
|
|
 |
|
| |
| As a sample, just a button. I'm going to introduce to
you a very complete Network Modeling tool. Mature, well designed, very
simple to use, full of options to simulate different kind of networks, and
the obvious choice for Fortune's companies and big universities. It's
also very, very, very expensive for people like us, poor mortals. |
| |
| Fortunately a limited (at no cost) academic version exists
that is good enough for our tests and for having a feeling about this
incredible tool. Have a copy of OPNET IT Guru Academic Edition software
at OPNET and go with me to
explore together this amazing analysis tool. |
| |
| Let me tell you that OPNET IT Guru is really a vast tool. Then, don't think I'm an
expert using it; I'm just in the learning process and I will be very
grateful to share with you, dear lectors, your experiences and discoveries
using this inexorable tool. |
| |
| First of all, sign up to the OPNET site and
get a copy of the academic version; check your environment to be
sure it supports the software to be installed. Then, install the
software. Like almost Windows software the instalation process is
very simple and straightforward. |
| |
| Execute the software; accept the SOFTWARE
AGREEMENT and you will have the following form in your screen
which is the software main menu: |

| |
| To continue with the explanation I'm going to use an alive
tool based on Macromedia Flash Player 8; you need then a browser as
Internet Explorer
or Firefox. Be sure you
have installed the last version of Macromedia Flash Player; it has no
cost and you can download it at
Macromedia. Download Internet Explorer and/or Firefox
clicking the links above. |
| |
| I'm going to record my computer screen using a 800x600
resolution. This way people using this low resolution can follow the
explanation in his/her browser. Then, for them it will be just a matter to
press F11 to put the browser in full screen presentation. |
| |
|
First part of our travel through OPNET IT Guru will be based in an
example they include in the product's tutorial. This example give us a
very fast introduction to the product and its features. It serves also
for you to taste the alive presentation. Later, I hope to travel as
long as we can throughout OPNET IT Guru to learn together how to use
the tool. |
| |
| Taken directly from the OPNET IT Guru's
tutorial a brief explanation of what we are planning to do as the first part
of the trip; from the tutorial we read: |
| |
| In this lesson, you plan for the expansion of a small
company’s intranet. Currently, the company has a star topology network on
the first floor of its office building and plans to add an additional star
topology network on another floor. You will build and test this “what-if”
scenario to ensure that the load added by the second network will not cause
the network to fail. |
| |
| Nothing more to say it's time to click the Next link below
to begin working. The movie lasts 12 minutes. |
| |
|
Very important note: depending on your browse configuration you
probably have to authorize emergency elements to play the next page. Don't
be afraid, this site is really very very safe. It runs on Linux. Do not
forget to press F11 key to show the movie in full screen. |
