Calculating DNP3 message loading on a radio path

Calculating DNP3 message loading on a radio path

Calculating DNP3 message loading on a radio path

(OP)
I need help calculating the message loading on a radio path between two PLCs communicating via DNP3.  

We are using 900 MHz radios in full duplex mode.  The radios will be configured for 9.6 kbps link capacity.

A brief summary of the data is as follows:

- A background poll of static data will be done every 4 hours
- One Class 1 event will occur each hour but five class 1 events are buffered before transmission
- One Class 3 event will occur every 10 hours but 25 of these events are buffered before tranmission

I need to determine if a 9.6 kbps link capacity will do.  

My approach is to calculate the maximum network traffic, based on the above data, that may occur at a given time to determine if the selected link capacity will do.  

I also thought of doing an hourly average but this would not account for periods of high traffic.  

Any comments?

Thanks in advance.
