Abstract: Systems and methods for automatic discovery of a network address of a machine storing a management server application. The system includes a dynamic host configuration protocol (DHCP) server, which may perform internet protocol (IP) address leasing for DHCP clients. When the DHCP server performs IP address leasing to the machine storing the management server application, the DHCP server may configure a first IP address issued to the machine in vendor specific class information. When the DHCP server performs IP address leasing to a computing device functioning as a thin/zero client, the DHCP server may, in the IP address leasing process, send the vendor specific class information requested to the computing device. Thus, the computing device may retrieve the first network address of the machine from the vendor specific class information, and communicate with the management server application using the first network address of the machine.

Abstract: Certain aspects direct to systems and methods for controlling heterogeneous internet of things (IoT) devices. The system includes a gateway device, which is communicatively connected to a control device under a first protocol and to multiple authenticated IoT devices under corresponding protocols. In operation, the gateway device receives a command from the control device, which is directed to a selected IoT device. Based on the command, the gateway device may select a corresponding API, and determine the corresponding network and the corresponding protocol specific for the selected IoT device. To send the command to the selected IoT device, the gateway device first determines whether the corresponding protocol for the selected IoT device is different from the first protocol. If so, the gateway device converts the command to a second command transmittable under the corresponding protocol for the selected IoT device, and sends the converted command to the selected IoT device.

Requests for read operations from the client computers for the client-specific boot data are then redirected to the consolidated boot volume, increasing boot performance for the client computers.
