    Intra-cluster communication protocol

    Yog Sothoth Newbie

      Just a quick question to confirm: what is the protocol for communication between cluster nodes? I understand that JGroups is used for cluster discovery, HotRod (and variety of others) is used for client/server communication, but i couldn't find anything in the docs about how cluster nodes communicate between each other for e.g. cache replication? What's the protocol difference between "sync" and "async" replication modes: is that TCP in the former and UDP in the latter, or something else? How can i fine-tune this protocol or even do basic configuration for it?
