WebSimilar asymmetric delay attack and solutions has been studied for time synchronization protocols like NTP and PTP [14-19]. In [14], the delay attacks for NTP and PTP are studied, and it proposes to measure the propagation delays during initialization of clock synchronization and to monitor the propagation delays during the normal WebJul 20, 2016 · The asymmetry in the network delay due to switches and routers can be corrected if they support a special correction field in PTP messages. A PTP-aware switch …
WebThe undo ptp asymmetry-correction command cancels the configured asymmetrical delay correction value on a 1588v2 interface. By default, the asymmetrical delay correction value is not configured on a 1588v2 interface. ... Either of the following parameters can be configured in the ptp delay-mechanism command to specify a delay measurement … WebAug 11, 2016 · The Delay_Requests and Delay_Responses are sent as unicast messages so that the slave ports do not have to drop them. An assumption here is that the bridge will not have an asymmetry between mulitcast and unicast messages since PTP assumes that the propagation delays of the Sync message and Delay_Request messages are the same.
WebOct 16, 2015 · The Precision Time Protocol (PTP) provides mechanisms to measure and take into account the delay asymmetry problem, such as the residence time … WebH04J3/0667 — Bidirectional timestamps, e.g. NTP or PTP for compensation of clock drift and for compensation of propagation delays. H ... Delay asymmetry is caused by the difference in optical index due to the difference between wavelengths (between λi and λj). Thus, according to the second embodiment shown in FIG. 7, the two Sync signals 13 ...
