Abstract: Rate reduction for an application controller is provided. Computing resources used by an application controller receiving an amount of traffic from a network device can be determined. A determination whether the computing resources used by the application controller are approaching a computing capacity of the application controller can be made. A message can be sent to the network device to reduce the amount of traffic sent to the application controller in response to a determination that the application controller is approaching the computing capacity. A reduced amount of traffic can be received from the network device. Incrementally increasing amounts of traffic can be received from the network device after receiving the reduced amount of traffic from the network device.

Abstract: An Edge switch. The edge switch includes a first module configured to receive multiple coupling signals from at least one user node. a second module, and a log. For each coupling signal, the coupling signal indicates coupling one of the at least one user nodes to one of at least one target nodes via one of at least one proxy servers, the first module is configured to determine an identity of the one of the at least one user nodes and an identity of the one of the at least one target nodes from the coupling signal, and the second module is configured to record the identity of the one of the at least one user nodes, the identity of the one of the at least one target nodes, and date and time at which the coupling signal was processed by the edge switch in an entry in the log.

Abstract: Systems, and methods, including executable instructions and/or logic thereon are provided for ternary content addressable memory (TCAM) updates. A TCAM system includes a TCAM matching array, a TCAM action array that specifies actions that are taken upon a match in the TCAM array, and a TCAM driver that provides a programmable interface to the TCAM matching array and the TCAM action array. Program instructions are executed by the TCAM driver to add a divert object which encompasses actions associated with the TCAM actions array and to apply the divert object to update action fields in the TCAM action array, without changing the relative order of entries in the TCAM matching array, while hardware is simultaneously using the entries.
