Abstract: Techniques are described for classification-based data security management. The classification-based data security management can include utilizing device and/or data attributes to identify security modes for communication of data stored in a source device. The security modes can be identified based on a hybrid-encryption negotiation. The attributes can include a device resource availability value, an access trust score, a data confidentiality score, a geo-coordinates value, and/or a date/time value. The security modes can include a hybrid-encryption mode. The source device can utilize the hybrid-encryption mode to transmit the data, via one or more network nodes, such as an edge node, to one or more service nodes.

Abstract: An indoor air quality monitor for an HVAC system includes a monitor body formed with a plurality of chambers defined at least in part by chamber walls. A bypass chamber allows for a majority of airflow entering the monitor to pass through. An intake chamber coupled to the bypass chamber allows for a portion of air to be removed for sampling by a particulate sensor. Air from the particulate sensor is discharged to an outlet chamber that is fluidly coupled to a downstream portion of the bypass chamber. The fluid requirements of the particulate sensor are maintained without overwhelming or underwhelming the particulate sensor.

Abstract: We describe a power converter cooling arrangement in which a base has a top plate of a thermally conductive material, and a bottom plate and side walls define a chamber. An inlet and outlet are in fluid communication with the chamber, and the chamber is flooded with a cooling fluid that flows between the inlet and outlet. A PCB of a power converter is mounted to, and thermally coupled with, the top plate, where the PCB receives a plurality of power modules (that are used in the power conversion). The base comprises a plurality of fluid channels for flowing cooling fluid therethrough. Each of the fluid channels is arranged to coincide with a location of one or more components mounted to the PCB.

Abstract: A method and system for controlling power consumption within a network node is disclosed. The method and system include dynamically controlling the power consumption of network processing engines based on predetermined thresholds. By dynamically controlling the power consumption of network processing engines based on predetermined thresholds, energy consumption of the overall network processing system is minimized, thereby reducing the operational costs of the system as well as increasing the overall efficiency of network operations. The method and system comprise allowing a queue to receive a plurality of data packets and dynamically controlling the power consumption of at least one of a plurality of processing engines based on a threshold.

Abstract: A network processor having a plurality of processing engines and packet assignment logic operable to selectively assign the received packets to the processing engines is disclosed. The packet assignment logic of the network processor distributes the received packets according to at least in part the packet size of previously distributed packets. In one embodiment, the packet assignment logic does not assign any packets to a processing engine that is already assigned a “large” packet. In this way, load balancing among the processing engines is improved, resulting in a higher performance network processor.
