Latest Patents
One of Helén's latest patents is titled "Method and detector for resolving unicast flooding." This invention discloses a method and a detector capable of resolving unicast flooding in a layer 2 broadcast domain. The method is performed in a detector that has a medium access control (MAC) address. The detector receives a first flooded packet with a destination MAC address that differs from its own. It then sends a message to a node in the layer 2 broadcast domain, determining the type of node based on the destination MAC address or the destination Internet Protocol (IP) address. This innovative approach helps to trigger the node to announce its MAC address, effectively resolving unicast flooding and reducing bandwidth consumption.
Another significant patent by Helén is "Managing data frames in switched networks." In this invention, a routing device and another routing device of a switched network form a virtual router, addressable by a virtual MAC address. The further routing device receives at least one data frame and sends a request to the routing device, instructing it to send an alert message that conveys information about the virtual MAC address throughout the switched network. This invention enhances the management of data frames, improving overall network performance.
