ZerocICE vs DDS

I know this question may seem like a duplicate, but I think newer versions of RPC frameworks are better compared again since I am new to RPC and HLA

my requirements:

• Realtime pub / sub messaging architecture, I have 12 nodes connecting each other and I want each process of my application to run multiple times on different VM servers on each node

• each process must be aware of its replicated process, if memory in one virtual machine goes up, the replicated process must support this process in parallel

• An error log occurred for each of the processes for tracing issue and number of lost messages

• I need RTI and HLA support for my modeling objects.

• why is DDS more used for critical systems such as military or air traffic control? is opensplice dds is that a lot of good things or OMG is supported and made by the military and DARPA guys as well: D?

do these structures provide such parameters (for open source DDS based on TAO ACE)?

What are my other options (like frugality)?

good comparison of these structures? Many thanks.
