Abstract
A method reduces cache memory requirements for testing a multiplicity of flows. The method includes receiving data corresponding to a frame in a particular flow among the multiplicity of flows. In response to the frame received, the method updates a set of cached flow counters in cache memory for the particular flow. The method updates one or more regular operation counters and one or more conditional counters among the set of cached flow counters, including a last serviced counter. The method updates, responsive to any error conditions, one or more error condition counters among the set of cached flow counters. The method evaluates whether to transfer values from the cached flow counters to system accumulators in system memory using at least a value in the last serviced counter for the particular flow. Responsive to the evaluating, the method transfers the values from the cached flow counters to the system accumulators.
