Understanding billing

Learn about the concept of message-minutes and how your simulation are counted.

How billing works in network simulator

The billing in Network Simulator is based upon the unit called message-minute. It is a simple concept based upon two parameters in your simulation: 

A) How long is your simulation going to last (in minutes)
B) How many messages you would be sending throughout your simulation (total)

Now multiply A with B and you get what we call message-minutes. E.g.

You are running simulation test1 with following parameters:-

100 clients repeating a message every 60 seconds 10 times.

Total message minutes, in this case, will be calculated as follows:-
The simulation will run for 60 seconds X 10 times = 10 minutes.
During this duration, 100 clients will produce 10 messages each. Therefore:-

1000 messages  X 10 minute = 10,000 message minutes.

Let’s take another example

1000 clients repeating a message every 10 seconds 60 times.

Total message minutes, in this case, will be calculated as follows:-
The simulation will run for 10 seconds X 60 times = 10 minutes.
During this duration, 1000 clients will produce 60 messages each. Therefore:-

60 X 1000 messages  X 10 minute = 600,000 message minutes.

Hope this help!
