Differentiation of dual-connectivity split-bearer wireless access
Systems and methods described herein enable differentiated policy enforcement for dual connectivity split bearer scenarios. A wireless station receives, from a core network associated with the wireless station, downlink packets directed to an end device that is using a dual-connectivity split bearer. The wireless station directs delivery of the downlink packets over different radio access networks (RANs) of the dual-connectivity split bearer. The wireless station logs a radio access technology (RAT)-type used to deliver each of the downlink packets and sends, based on the logging, a downlink RAT-type feedback report to a network device in the core network. The wireless station receives uplink packets from the end device using the dual-connectivity split bearer, marks each of the uplink packets with a RAT-type indicator, and forwards the marked packets to the network device in the core network. |

Lossless compression techniques for single-channel images
Disclosed herein are techniques for performing lossless compression of single-channel images (e.g., grayscale images). A first technique involves pre-processing an isolated (i.e., one) single-channel image for compression. In particular, the first technique involves calculating predicted pixel intensity values (within the single-channel image) based on neighboring pixel intensity values (also within the single-channel image). Bit values of the error margins of the predicted pixel intensity values are separated into two different byte streams according to a particular ordering, whereupon the byte streams are separately compressed (e.g., using a Lempel-Ziv-Welch (LZW)-based compressor) and joined together to produce a compressed single-channel image. A second technique involves pre-processing a group of single-channel images into one single-channel image for compression. In particular, the second technique involves interleaving pixel intensity values of the single-channel images to produce an interleaved single-channel image, and subsequently compressing the interleaved single-channel image (e.g., using an LZW-based compressor). |

Method and system for reclaiming unused resources in a networked application environment
Techniques are disclosed for reclaiming resources within a distributed computing system. A reclamation application searches the distributed computing architecture for unused resources, classifies the unused resources, and determines an expiration period based on the classification.

Techniques for managing resource consumption for demand-based metering
A demand management module may determine a demand interval that is associated with an electrical utility provider. In addition, the demand management module may determine a threshold amount of electricity received by an electrical meter during the demand interval.
