Sending Topics from the same publisher in different IP packets

Hi,

Is it possible to send different DDS Topics from the same publisher in different IP packets.

Example, a publisher has 3 Topics A, B and C each with different QoS settings ans data types. 

Topic A may be sent in IP packet 1, Topic B in another IP packet 2 and Topic C in another IP packet.

If so, how we can do this? Is there any documenttion about the that in the reference manual ?

 

Regards

Hello Hakiri, 

This is the default behavior in RTI Connext DDS.  If you are using different Topics, you must use different DataWriters.  As long as data is being written by different DataWriters, the data will be sent in separate IP packets.

Thank you!

Rose
