+
+Introduce a rpc call to get device details for multiple devices instead of one
+by one.
+
+
+Problem description
+===================
+
+An agent needs to communicate with Neutron server in order to get some infomation
+about the devices (to handle devices added for example).
+Currently there's an rpc call that can be used by the agent to get the details
+of a device, get_device_details . This call needs to be issued for each device.
+See neutron/agent/rpc.py .
+
+The purpose of this blueprint is to add a call to get the details of multiple
+devices. This way instead of making N calls for N devices only one call will be
+made.
