+// The implementation of the open flow agent (ofagent) uses a GRPC connection
+// to VOLTHA accross several implementaton packages including the ofagent and
+// openflow packages. This GRPC connection is shared through packages and type
+// instances via injection.
+//
+// As the ofagent executes within a micro-service environment it is
+// possible that the GRPC connection is reset (re-established). When the connection
+// is re-established, because injection is used, the new value needs to be
+// re-injected across the implementation.
+//
+// To help simply the re-injection or value change scenario a holder for the
+// GRPC connection is established so that the reference to the holder can
+// stay [sic] consistant over the lifetime of the ofagent while the underlying
+// GRPC connection can change without walking the entire runtime structure.
