DDS's Real-time Publish-Subscribe (RTPS) protocol is only specified for UDP for a good reason, it is a broadcast protocol. Sure you can run the higher layers over TCP, which is what OpenDDS does (they actually use CORBA on top of), but then you lose interoperability.

RTPS is multicast, not broadcast.
