Abstract: Methods and apparatus for low-latency link compression schemes. Under the schemes, selected packets or messages are dynamically selected for compression in view of current transmit queue levels. The latency incurred during compression and decompression is not added to the data-path, but sits on the side of the transmit queue. The system monitors the queue depth and, accordingly, initiates compression jobs based on the depth. Different compression levels may be dynamically selected and used based on queue depth. Under various schemes, either packets or messages are enqueued in the transmit queue or pointers to such packets and messages are enqueued. Additionally, packets/message may be compressed prior to being enqueued, or after being enqueued, wherein an original uncompressed packet is replaced with a compressed packet. Compressed and uncompressed packets may be stored in queues or buffers and transmitted using a different numbers of transmit cycles based on their compression ratios.

Abstract: A tracking device can securely communicate with a secondary device by generating a hash value based on the identity of the tracking device. If the secondary device cannot resolve the hash value, the hash value can be provided to a tracking server, such as a cloud server, for resolving the hash value. Upon resolving the hash value, the tracking server can store a location of the tracking device in association with the identity of the tracking device. To preserve power, the secondary device can activate location-detection functionality (such as a GPS receive) only in response to the detection of movement of the tracking device, can obtain location information, and can de-activate the location-detection functionality upon providing the location information to the tracking server. The tracking server can associate one or both of a previous location and the current location information based on movement of the tracking device.
