Abstract
Systems, methods and computer-readable storage devices each provide, for a given flow entry in a flow table associated with a packet flow, a first atomic counter associated with a first color and a second atomic counter associated with a second color. The system, for a first coloring interval, marks traffic in the packet flow from a tenant to a fabric as the first color and increments the first atomic counter. At a conclusion of the first coloring interval and for a second coloring interval, the system marks the traffic in the packet flow from the tenant to the fabric as the second color and increments the second atomic counter. The system compares first packet counts associated with the first color at an ingress point with second packet counts associated with the first color at an egress point to the fabric.
