Latest Patents
One of Sze-Wa Lao's latest patents focuses on network control software notification and invalidation of static entries. This innovation discloses techniques for notifying network control software of new and moved source MAC addresses. In one embodiment, a switch may redirect a packet sent by a new or migrated virtual machine to the network control software as a notification. The switch does not forward the packet, thereby protecting against denial of service attacks. Additionally, the switch adds a temporary entry to a forwarding database that includes a 'No_Redirect' flag for a new source MAC address or updates an existing entry for a source MAC address that hits in the forwarding database by setting the 'No_Redirect' flag. This flag indicates whether a notification has already been sent to the network control software for this source MAC address. The switch may periodically retry the notification to the network control software until the source MAC address is validated, depending on whether the 'No_Redirect' flag is set.
