Data-driven identification of features related to a state change of a network component
Techniques and mechanisms for automatically identifying counters/features of a network component that are related to a state change (or event) for the network component or for the network itself. For example, using data obtained from the network component around a time of the state change, delta averages for the features around the time of the state change may be determined.

Thus, the techniques described herein provide for an approach to distill which counters/features contribute the most to a particular state change from a data driven perspective. |

Scheduling around frame based equipment (FBE) idle periods reduces the flexibility of scheduling and partitioning.
