Controller Side
The ONOS control plane is extended with the server device driver, which is part of the ONOS drivers sub-system.
The server device driver exploits ONOS's REST-based Southbound Controller (i.e., RestSBController) to register server devices as REST-based devices.
As such, every commodity server registered to ONOS (through the server device driver) is represented as a RestServerSBDevice, which extends ONOS's RestSBDevice.
The extensions of RestServerSBDevice are related to the CPU and NIC resources present in commodity servers (but not present in other REST-based devices).
Server Side
At the server side we need a process that is able to communicate with the server device driver using a REST-based channel (i.e., HTTP messages).
First, each server must "register" with the controller using the onos-netcfg facilities as follows:
