    摘要： In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.

    摘要： In one embodiment, the techniques herein provide that a node may receive indicia of a fault state in one or more components of a computer network. Based on the indicia, the node may then identify a network dependency group including a plurality of network components that are hierarchically associated with the one or more components. The node may then receive, from a database, a time series of performance data values corresponding to the network dependency group, wherein the time series comprises performance data values from before and after the onset of the fault state. The node may then identify altered performance data values in the time series comprising values which differ before and after onset of the fault state, and then determine a root cause of the fault state by identifying one or more particular components within the network dependency group that are associated with the altered performance data values.
