Abstract: The present disclosure relates to a clock distribution method and apparatus in a network. The method performed at a first clock distribution apparatus comprises: determining (S101) whether the first clock distribution apparatus is in a lock state; and transmitting (S102), to a second clock distribution apparatus, a first announce message when the clock distribution apparatus is not in the lock state; wherein the first announce message is generated based on a default configuration about a local clock state of the first clock distribution apparatus. According to embodiments of the present disclosure, the clock distribution apparatus may generate first announce messages based on a local clock state of the clock distribution apparatus. Thus, a downstream apparatus which receives the first announce messages may avoid selecting an unstable/unlocked clock distribution apparatus as the best master, based on the local clock state of the clock distribution apparatus.

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: A computer-implemented method for treating post-modeling data includes computing, sequentially for each category of a feature, a category importance (CI) value. The CI value is based on a model accuracy change when records of a category being examined are reassigned to a remaining set of categories of the feature according to a cumulative distribution of records among the remaining set of categories of the feature, wherein the remaining set of categories include all categories of the feature, except for the category being examined. A post-modeling category is performed to merge of each category having the CI value less than a CI value threshold.
