If you are trying to transfer data directly between two nodes on the same network and minimizing latency is your number one priority you may want to consider RTI DDS. The downside is you will need to figure out how to configure the routing information and security for the deployed systems, especially as networks change.
If you are trying to aggregate data to a central location or centrally configure things and you want a solution that automatically takes care of the routing and security consider using Skyline Data Services.
