Appl. No.:

16/538074

- New York NY, US
Yu-Chin Tai - Sunnyvale CA, US

International Classification:

G06F 16/29
G06F 16/9535

Abstract:

As provided herein, a list of locales of interest in a location may be sorted into one or more categories. A user performing a search for a locale of interest (e.g., a restaurant) may be identified. A local score may be assigned to the locale of interest based upon a number of local users (e.g., users residing in the location) that perform the search. A second user may be determined to be near the locale of interest. A category of interest may be determined for the second user (e.g., an interest in local non-tourist restaurants). Responsive to the category of interest corresponding to the category and the local score of the locale of interest exceeding an interest threshold, the second user may be provided with a recommendation to go to the locale of interest. The locale of interest may be a local favorite restaurant rather than a tourist trap.

International Classification:

H04L 12/24
G06F 17/30

Abstract:

Techniques are disclosed for notifying network control software of new and moved source MAC addresses. In one embodiment, a switch detects packets sent by a new or migrated virtual machine, and sends a copy of a detected packet to the network control software as a notification. The switch further learns the source MAC address, thereby permitting the entry to be used for normal forwarding prior to validation of the entry and the VM associated therewith by the network control software. Until the network control software has validated the VM, the switch may periodically retry the notification to the network control software. “No_Redirect” and “Not_Validated” flags may be used to indicate whether a notification has already been attempted and thus no retry is necessary, and that the VM associated with the VM has not yet been validated, respectively.

International Classification:

H04L 12/24
G06F 17/30

Abstract:

Techniques are disclosed 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. The switch further adds to a forwarding database a temporary entry which 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. The “No_Redirect” 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 network control software validates the source MAC address, depending on whether the “No_Redirect” is set.
