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.

Abstract: Systems and methods are described for maintaining communication between hosts that, due to the roaming of a host, are no longer in the same LAN segment within a network. In one embodiment, the method includes receiving an address resolution request from the first host, the address resolution request requesting an actual media access control (MAC) address associated with an internet protocol (IP) address of the second host, obtaining the actual MAC address of the second host, the second host having roamed from away from a first network location where a first host is located, receiving a data packet from the first host that is to be delivered to the second host, and routing the data packet to the second host at its current location, the current location of the second host being determined by its actual MAC address.
