Abstract: Techniques are disclosed for providing a Software Defined Networking (SDN) controller with real-time or near-real time visibility of the operation of data center fabrics to determine whether the DCI was properly configured. For example, an SDN controller receives high-level configuration data that describes a desired state of a network managed by the SDN controller at a high level of abstraction. The SDN controller applies a transformation function to the high-level configuration data to generate a low-level configuration data for network devices configured to implement the desired state of the network. SDN controller configures the SDN controller as a peer to the network devices to obtain one or more routes exchanged between the network devices. The SDN controller sends the low-level configuration data to the network devices to cause the network devices to implement the desired state of the network.

Abstract: A network device includes match filters to be applied to packets transiting two or more network interfaces. In one example, a network device includes a filtering unit configured to apply one or more filters to a first packet transiting a first network interface to determine a first rule the first packet matches, send the first packet and data representing the first network interface to a first accounting filter associated with the first rule, apply the filters to a second packet transiting a second network interface to determine a second rule that the second packet matches, the second packet being different than the first packet, and the second network interface being different than the first network interface, and send the second packet and second data representing the second network interface to a second accounting filter associated with the second rule.
