Evaluating the impact of transceiver temperature on interface utilization

Abstract:

In one embodiment, a device obtains temperature and utilization measurements for a set of network interface transceivers in a network. The device computes, for each of the transceivers, a correlation coefficient between its temperature and utilization measurements. The device applies a k-nearest neighbor classifier to the correlation coefficients, to predict a correlation coefficient. The device uses the predicted correlation coefficient to determine an impact of temperature on utilization of a particular network interface transceiver. The device initiates a mitigation action, when the determined impact of temperature on the utilization of the particular network interface transceiver exceeds a predefined threshold.
