Abstract: A method and a network device are disclosed for precision time protocol (PTP) clock synchronization. According to an embodiment, a network device determines first estimates of offsets between a slave clock of the network device acting as a PTP slave and a master clock of a PTP master, based on timestamps related to PTP messages communicated between the network device and the PTP master. The network device determines whether there is a change in at least one of a first path from the network device to the PTP master and a second path from the PTP master to the network device. When determining that there is a change in at least one of the first path and the second path, the network device updates the first estimate of the asymmetry based on the first estimates of the offsets.

Abstract: Methods and systems are described for providing hierarchical demand forecasting for state space reduction. Using a hierarchical architecture, a base model may be trained to capture a range of shared structure in a first data set that can be used to draw inferences on using smaller sets of data representative of the “whole picture.” For example, training data may be sampled and prepared and used to train a base model in a first stage. In a next stage, one or more downstream models may be trained on the structure and samples of uncensored demand generated by the base model to produce forecasts for items and locations, including items and locations for which there may be little or no historical data. The downstream models that would otherwise require a large amount of data for training can be generated on demand using less training data, training time, computing processing, and memory.
