Hi,

DDS will automatically fragment and re-assemble large data. SO you do not have to worry about this. The only thing is that you may want to use a FlowController to throttle the rate at which data it put on the network.

There is an example application that sends large data in the File Exchange. You can access it at this link: large_data.zip. (https://community.rti.com/filedepot?cid=5&fid=25)
