| 3.0.- Creating the
Application and Profile Objects |
|
|
| |
| The first step when using OPNET IT Guru is to create
the Application Object and the Profile Object. The
Application Object will contain all the type of applications you
want to run in your network models; for example, Database, Ftp,
Email, Http Browsing, etc., etc. Once you have defined
the type of applications you want you need to create a Profile
Object where you define different kind of profiles and indicate
which applications each profile should run. |
| |
| These objects, the Application Object and the
Profile Object must be included in your models, since they are the
engines that drive your model. In fact they inject traffic to your
network models to be tested and evaluated. |
| |
| In the next lesson we are going to show you an alive
presentation of how you create the Application Object and the
Profile Object. But here let's include some images taken from the
OPNET IT Guru software showing you the Application and
Profile Objects attributes. Don't be afraid if you don't
understand just now how these images are obtained. They are presented
here for you to use them as a support when you create your own objects.
Print this page and enjoy creating them. |
| |
| First let's show you the attributes window of one
Application Object we created to drive our models. We decided to include the
following applications: Database (low, medium and high load),
Email (low, medium and high load), Http (light, heavy and image
browsing), Print (text files and color prints), VoIP, Ftp
(low, medium and high load), Video Conferencing (high resolution and
VCR quality video) and Remote Login (low, medium and high load). |
| |
| What all this means? That when we want to create a new
profile (for example, one people from the Finance Deparment) we can
combine from these applications what we want to define the profile.
Finance? Okay, let's suppose he/she uses: Database in
medium load, Email in medium load, light browsing in Http,
mmm... yes ... Print but just text files.. etc., etc. |
| |
| Do you catch the idea? Having your
available applications you define the profiles and later
on you apply a profile to each workstation. When
you drop a Workstation object in your network model
you define: in this Workstation the profile to be used
is: Finance. And the Finance Profile Object
already contains all the applications you previously assigned to it.
Okay, let me show you the Application Object attributes window: |
|
|
| |
| In the window you can observe that because we don't want to
be self limited we created an Application Object with 21
different kind of applications: Three level of load for Database,
Email, Http, Print, Ftp and Remote Login
applications and two types of Video Conferencing and VoIP too. |
| |
| Having this pool of available applications let's now think
a little about profiles. We will begin imagine an office and what kind of
different profiles we could have. Without squeezing to much our brain we
decided to include profiles for people from these deparments:
Secretary, Accounting, Human Resources, Engineering,
Marketing, Research & Development, Sales & Collections,
Purchase & Payments and Management. Just nine kind of
deparments. Of course, you are free to elucubrate and create new profiles
and then populate each profile with the applications you want. |
| |
| How do we populate our defined profiles? Well, again
it's a matter of your own judgment. For example, for the Secretary
Deparment, or any secretary in a secretary pool we decided
to include four (4) applications: Database (low load),
Email (medium load), Http (light browsing) and Print (text
files). Again it's a matter of choice. No one is going
to prevent you from having a secretary pool using Http with
heavy browsing or using VoIP too. |
| |
| Okay, let me show you our Profile Object attributes
window; but this time I need more than one image because I want you to have
these if you want to use them to populate your own profiles. |
| |
|
|
| |
| This first image shows the Secretary profile and the
Accounting profile. For example, below the Profile Name (Secretary)
you will see the four applications assigned to this profile: Database (low load),
Email (medium load), Http (light browsing) and Print (text
files). Accounting also has four applications but slightly
differents. |
| |
|
|
| |
| The second image is for Human Resources and
Engineering. |
| |
|
|
| |
| The third image is for Marketing and Research &
Development. |
| |
|
|
| |
| The fourth image is for Sales & Collections and
Purchases & Payments. |
| |
|
|
| And finally Management. |
| |
| In the next lesson we are going to have an alive
presentation of how to create these objects using OPNET IT Guru. See
you later after the movie (it lasts 9 minutes), dear guys. |
