Master/Slave is the old legacy way to obtain a resilient system. It's easier to setup, but if you are already on SolrCloud I can not see any advantage in moving back. Related the networking part, I am not a network expert. The only think I can tell you is that the inter-nodes communication is going to happen on the same REST endpoints and handlers which are used for search/updates ( same java process). I really doubt it is possible to have them running across different physical network interfaces.
