2. Telnetservice was used to enable SCADA manager to login to any
substation remotely to watch and fix errors.
3. Videostreaming was used to represent camera capture real video to
feeders and transformers and transmitted as ( 640 * 480 pixels, 24 bit
color intensity and 30frames/sec) to server for displaying. Each
frame consists of 921600 bytes, but with 70% image compression of
transmitted video data, it becomes 276480 bytes [ 74 ].
4. VOIP service for communication from /to a substation and the
central server. The data type used wasPCM (Pulse-Code Modulation)
Quality and Silence Suppressed [ 75 ].
5. Video conference was used for SCADA system managers to
communicate with each other where the type of video data was
(240*128 pixel, 9bits color intensity, 15 frame/sec, and 70% image
compression of transmitted video data.
6. All the previous applications and services were collected and
implemented in one scenario.
- 7 .4 Configuration of Network Simulation:
The following sub-sections represent the steps taken before
running the network simulation:
- 7 .4.1 StatisticsSelection:
Once the design of the network model was done,a number of
statistics would be selected to specify the results that clarifythe
performance of the network applications.The statistics selected were:
Global Statistics: These statistics get updated by all the
nodes/linksin the network. This was represented by Response Time or
Packet End-to-End Delay in (sec).
