Latest Patents

One of Hoffmann's latest patents addresses the issue of protecting a network from a unicast flood. This approach involves a method where, if the destination MAC address of a frame is not found in a table of unknown MAC addresses, the MAC address is added to the table. The frame is then forwarded to non-blocked spanning tree links to locate the MAC address within the network. If the MAC address is already in the table and a timer for suppressing frame forwarding is active, the frame is discarded. Conversely, if the timer is inactive, a counter for counting received frames is incremented and compared to a threshold value. If the counter exceeds the threshold, the timer is activated, and the frame is discarded. If not, the frame is forwarded to the non-blocked spanning tree links to find the MAC address.
