To be precise,
[Legend: <---> denotes two-way communication]

* GlusterD 2.0 <---> GlusterD 2.0, brick processes, Gluster daemons, mount processes (akpa clients) - protobuf-based RPC

* GlusterD 2.0 REST service <--> REST clients - JSON/HTTP

(This one remains as is)
* A = {brick processes, Gluster daemons, mount processes}
  All members of "A X A" use XDR/SunRPC for communication. This communication is out
  of scope for GlusterD 2.0 effort and isn't affected due to changes in GlusterD 2.0's
  messaging layer.
