Abstract:
1. A method of determining activity in a network, comprising: determining a plurality of frame flows in the network whose activity is to be monitored; partitioning, by a processor, a first portion of said plurality of frame flows into a first set and a second portion of said plurality of frame flows into a second set, each frame flow having an associated count value, periodically determining frame flow activity for the frame flows having associated hardware counters and updating the associated count values for said frame flows; sorting all frame flows based on count values; assigning frame flows with the highest count values to said first set and configuring the hardware counters as required; and assigning the remaining frame flows to said second set and changing which frame flows of said second set have associated hardware counters and configuring the hardware counters as required so that all frame flows in said second set are periodically associated with hardware counters to determine count values.
