This page offers you an introduction to Westplan through a number of
screen images. For more information, you can view the user guide. |
|
|
| Westplan's work is automatically starred in a local database which can be
displayed in either Outlook Mode (similar to Microsoft Outlook) or Explorer Mode (similar
to Windows Explorer). The following image shows Westplan in its Outlook Mode:

Westplan in Explorer Mode

|
|
| The following image shows Westplan in its Explorer Mode. This is
useful if a large number of projects or networks have been defined: 
|
|
|
| In the above images, a project with six nodes is shown. Each
network defines a way in which its project's nodes are inter-connected. Inter-nodal
links are added using simple point and click, and their transmission facilities are
specified using the following dialogue box: 
The contents of the bottom section vary depending upon the link type
selected in the top section. The example above shows a Voice over IP link. |
|
|
| If voice over IP is to be analysed, then the VoIP parameters above layer
two are defined on a project-wide basis: 
|
|
|
| Although Westplan assigns default traffic levels to a project when its
nodes are added, it is best to change these yourself to reflect the call volumes between
your nodes. These figures can either be entered in Erlangs of busy hour traffic or
minutes of traffic per day: 
|
|
|
| As a default, Westplan assumes that calls will be routed through a
network using the shortest path. If this routing is not appropriate, then you can
define your own routing rules using simple point and click. Once defined, they will
appear in the routing drawings as animated highlights of the specified links: 
|
|
|
| Once traffic levels have been entered, networks can be optimised.
During the optimisation process, Westplan calculates the traffic levels offered to
each link, and recommends the facilities that should be deployed on each link for the
quality of service to remain within the constraints that you can specify. The links
in the network drawings change colour to indicate whether the suggestion is to increase or
decrease the deployed facilities. More detailed information on each link can be found
under the Links tab above the workspace:

|
|
| Each calculation is justified in a printable report. This is
particularly useful when interpreting the complicated calculations involved in Voice over
IP bandwidth dimensioning:
