Abstract: Methods and apparatus are provided for managing data flows in a switch connected in a network. Such a method includes monitoring a set of data flows traversing the switch for compliance with a predetermined resource-usage policy, and, in response to detection of a non-compliant data flow, mirroring a set of data packets of that flow to send respective mirror packets to a mirror port of the switch. The method further comprises using the mirror packets sent to the mirror port to construct a non-compliance notification for the non-compliant flow, and sending the non-compliance notification into the network. The resource-usage policy can be defined such that the switch is operable to send a non-compliance notification before occurrence of congestion due to the non-compliant flow.

Abstract: Distinct sets of non-stationary data seen on a switch in data communication with one or more of computerized units in a network, are mirrored via two switch ports, which include a first port and a second port. A dual analysis is performed while mirroring said distinct sets of data. First data obtained from data mirrored at the first port are analyzed (e.g., using a trained machine learning model) and, based on the first data analyzed, the switch is reconfigured for the second port to mirror second data, which are selected from non-stationary data as seen on the switch (e.g., data received and/or transmitted by the switch). The second data mirrored at the second port is analyzed (e.g., using a different analysis scheme, suited for the selected data).
