Abstract: Techniques to facilitate verification of in-situ network telemetry data of data packet of data traffic of packet-switched networks are described herein. A technique described herein includes a network node obtaining a data packet of data traffic of a packet-switched network. The data packet includes an in-situ network telemetry block. The network node obtains telemetry data and cryptographic key. The cryptographic key confidentially identifies the network node. The node encrypts at least a portion of the telemetry data based on the cryptographic key to produce signed telemetry data and updates telemetry-data entry of the in-situ network telemetry block. The telemetry data and signed telemetry data is inserted into the telemetry-data entry. The node forwards the data packet with the updated telemetry-data entry to another network node of the packet-switched network.

Abstract: In one embodiment, a method includes activating a first network apparatus within a network and determining, by the first network apparatus, that a Scalable Group Tag (SGT) Exchange Protocol (SXP) is configured on the first network apparatus. The method also includes costing out the first network apparatus in response to determining that the SXP is configured on the first network apparatus. Costing out the first network apparatus prevents Internet Protocol (IP) traffic from flowing through the first network apparatus. The method further includes receiving, by the first network apparatus, IP-to-SGT bindings from an SXP speaker, receiving an end-of-exchange message from the SXP speaker, and costing in the first network apparatus in response to receiving the end-of-exchange message. Costing in the first network apparatus allows the IP traffic to flow through the first network apparatus.

Abstract: An underwater image projection system submerged in a body of water and projecting an image within the body of water. The system includes a submerged projection element, a light source steering device, a user interface, and a controller. The submerged projecting element includes a projecting light source that projects an image within the body of water. The light source steering device directs light from the projecting light source. The user interface receives data input from a user including at least one of an input of the image and instructions for displaying the image. The controller retrieves the data input from the user interface, accesses image data corresponding to the image, and controls the projecting light source and the light source steering device to project the image onto a target surface within the body of water based on the data input from the user interface.

Abstract: Computerized systems and methods are provided to intelligently and dynamically manage a data center comprising at least one server and at least one central manager. The central manager is programmed to access the at least one server on a predetermined schedule to determine whether at least one application is functioning properly by determining a functionality level. Alternatively, the central manager determines whether the at least one server is actively used by determining an activity level for the server. Based on the central manager's determinations, the system dynamically adjusts the power level of the server, resulting in reduced power consumption and a reduction in wasted resources and unnecessary processing power in the management of servers in a data center.

Abstract: A circuit interface includes a plurality of inputs, an internal controller, and a communication module. Each of the inputs may be configured to connect to a respective high voltage relay output of a pool and/or spa control (“PSC”) panel. The internal controller may be connected to the plurality of inputs, and together, the internal controller and the plurality of inputs can be configured to convert relay output signals into formatted data that includes an implementation protocol. The communication module can be configured to transmit the formatted data from the circuit interface. Conversions from the relay output signals to the formatted data can include specifying or configuring the formatted data to cause a device controller to operate devices corresponding to respective PSC panel relay outputs by directing individual low voltage supplies from a common low voltage source to the respective devices.

Abstract: Systems and methods for operating lights can include stepping down a high voltage power supply and transmitting a resulting low voltage through a relay to a light. A device controller system can receive a selected mode for operating the light including a setting for brightness, color, or operation scheme. The selected mode can be converted into a command configured to cause the light to operate continuously while changing from a current mode of operation to the selected mode. The system can determine an operation sequence for the relay to convey the command to the light. A schedule for the operation sequence can include a zero cross operation by the relay indicating, to the light, the setting or an operation mode change. The relay can operate according to the operation sequence and the schedule and the light can change to from the current mode to the selected mode without delay.
