    摘要： A system for managing holdover. The system may include a local oscillator device. The system may include a phase locked loop (PLL) device coupled to the local oscillator device and a reference clock source. The PLL device may obtain a reference clock signal from the reference clock source to produce an extracted clock signal. The system may include a drift monitoring device coupled to the local oscillator device and the PLL device. The drift monitoring device may determine an amount of oscillator drift within the local oscillator device using the extracted clock signal and an oscillator signal from the local oscillator device. The system may include a drift compensation device coupled to the drift monitoring device and the PLL device. The drift compensation device may transmit a drift compensation signal to the PLL device based on the amount of oscillator drift.

    摘要： A system includes a first blade including a first side of the first blade, a second side of the first blade, a front of the first blade, and a back of the first blade. The system further includes a second blade including a first side of the second blade, a second side of the second blade, a front of the second blade, and a back of the second blade. The system further includes a first side plane including a first physical communication channel configured to communicatively connect the first blade to the second blade via the first side of the first blade and the first side of the second blade.

    摘要： The present disclosure relates to Ethernet synchronization systems and methods that combines Synchronous Ethernet (Sync-E) and Precision Time Protocol (PTP) IEEE 1588 algorithms. The present invention includes systems and methods for Ethernet networks and node configurations that include a set of rules on node placement, such as Boundary Clock (BC) nodes and Sync-E nodes, a clock selection algorithm, a holdover algorithm, and the like. Advantageously, the present invention provides an architecture that allows practical and real-world useful clock propagation through placement of BCs and Sync-E nodes for best performance. Practical experience and theoretical design are embodied in the present invention to define a very specific set of rules on how to build a network capable of providing accurate and reliable synchronization. The present invention includes clock selection that unifies Sync-E and 1588 algorithms.
