Bandwidth calculation example

On this page you can find a bandwidth calculation example that allows you to see how the bandwidth capacity of Ozeki NG SMS Gateway works.

In case of SMPP connection that has a bandwidth capacity of 5 MPS (Message Per Second), 5 MPS refers to the fact that outgoing and incoming message capacity together will be 5 messages/sec.

SMPP connection with 5 MPS:

incoming + outgoing messages = 5 messages / second 

Please note that in all the examples below it is assumed that there is no incoming messages and no delivery reports

If you go to "SQL for sending" tab of the Database user you can find this option: "Check the ozekimessageout table every ... sec. for outgoing messages" (Figure 1). By default this value is set to "10". In practice it means that the Database user will check the "ozekimessageout" table for outgoing messages in every 10 seconds.

Below on "SQL for sending" tab you can also find "Maximum number of messages to send with one poll:" option. By default it is set to "10". It refers to the maximum number of messages to be sent out with one poll. In practice it means that 10 messages will be sent with one "Select" statement.

So with the default settings in Ozeki NG SMS Gateway 10 messages are sent in every 10 seconds that will take 2 seconds with the 5 MPS connection.

10 messages / 5 MPS = 2 seconds 

If you set the time of checking the ozekimessageout table for outgoing messages to a lower value - for example to "5" - and you leave the default number of messages to be sent out (10 messages) it will also take 2 seconds with 5 MPS connection (Figure 2). In this case the process requires the same period of time but the user will check the "ozekimessageout" table for outgoing messages more often (in every "5" seconds instead of "10").

Assume that we want to send out 1000 messages (with 5 MPS SMPP connection).
If you use the settings of "Example 1": the user checks for outgoing messages in every "5" minutes and maximum "10" messages can be sent out with one poll then 100 polls are required to send out the messages. As the user checks the "ozekimessageout" table in every "5" seconds it needs 500 seconds (8,3 minutes) to poll and send out 1000 messages. So there is enough time to send out messages between two polls.

500 seconds / 60 = 8,3 minutes
