Does anybody knows if I can run RTI´s protocol Connext DDS in Arduino?
I suspect if Googleing "Connext DDS in Arduino" doesn't turn up an useful results, then its not been done before.
Looking at the data sheet http://www.rti.com/docs/RTI_Pro.pdf This looks like something more complex than the Arduino boards could handle.
You're probably better off using a Raspberry PI for this (however you'd need to determine if it had been done already on RPI - I suspect not, as it seems a niche protocol)
Apparently it can be done on Raspberry PI.
Cool. RPI is probably the best platform for this.
