RPC is a standard way of interacting between Neutron server and agents Using neutron client is also inefficient as it results in unneeded keystone load and may become a bottleneck at scale DocImpact When upgrading, one should upgrade neutron server first, then metadata agent. However there is a fallback in case metadata agent fails to get info from server by rpc - it will return to using neutron client.
