METHOD AND APPARATUS FOR ADVANCED STATISTICS COLLECTION

Systems, methods, and computer-readable media provide for collection of statistics relating to network traffic between virtual machines (VMs) in a network. In an example embodiment, a virtual switch hosted on a physical server provides network address information of VMs deployed on the physical server to a virtual switch controller. The controller collects this network address information from each virtual switch under its control, and distributes the aggregate address information to each switch. In this manner, the controller and each switch within the controller's domain can learn the network address information of each VM deployed on physical servers hosting switches under the controller's control. Each virtual switch can determine a classification of a frame passing through the switch (e.g., intra-server, inter-server and intra-domain, or inter-domain traffic), and statistics relating to the traffic. In an example embodiment, the virtual switch controller can collect the statistics from each switch within its domain.
