  • Protecting a network from a unicast flood
    Patent number: 10623196
    Abstract: An approach is provided for protecting a network from a unicast flood. If the destination MAC address of a frame is not included in a table of unknown MAC addresses, the MAC address is added to the table and the frame is forwarded to non-blocked spanning tree links to find the MAC address in the network. If the MAC address is included in the table, and if a timer for suppressing forwarding of frames is active, the frame is discarded, or if the timer is inactive, a counter for counting received frames is incremented and compared to a threshold value. If the counter is greater than the threshold value, the timer is activated and the frame is discarded. If the counter is not greater than the threshold value, the frame is forwarded to the non-blocked spanning tree links to find the MAC address in the network.

  • Multi-band link-aggregation pre-negotiated power save modes
    Patent number: 10609647
    Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.
