Abstract: A network function virtualization (NFV) compute element installs an image supporting a virtualized network function (VNF) on the element. The image includes instructions/data to initiate a TCP connection between the element and a Software Defined Network (SDN) controller upon reboot of the element. Upon rebooting, the element establishes, as client in accordance with the instructions/data, a TCP connection with the controller. The element then accepts, as a cryptographic network protocol server, a connection via the TCP connection from the controller as a client in accordance with the instructions. Next, the element accepts, as a network management protocol server, a connection via the cryptographic network protocol connection from the controller as network management protocol client. The element receives, from the controller over the network management protocol connection, commands regarding the status of the rebooted element, and then transmits, to the controller over the network management protocol connection, responses to the commands.
