International Classification:

H04L 12/56

US Classification:

370419

Abstract:

A Layer network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.

International Classification:

G06Q 30/00

US Classification:

705 1453

Abstract:

The present invention provides techniques including determining or providing guaranteed delivery advertising offers or products based at least in part on advertisement retargeting related information, such as predicted, forecasted, or assessed advertisement retargeting serving opportunities over a period of time. Historical user online activity information may be obtained, patterns leading to retargeting opportunities may be determined, and, based at least on the determined patterns, a prediction or assessment may be made of future retargeting opportunity availability. Guaranteed delivery advertising offers or products, or parameters thereof, may be determined based at least in part on the prediction or assessment.

Appl. No.:

13/462976

Inventors:

Ayman Farahat - San Francisco CA, US
Tarun Bhatia - Simi Valley CA, US
Eric Bax - Altadena CA, US

Assignee:

Yahoo! Inc. - Sunnyvale CA

International Classification:

G06Q 30/02

US Classification:

705 1443

Abstract:

Techniques are provided that can be used in experimentation in online advertising. In an experiment, a short, recurring time interval during a period may be divided into a set of segments. Serving opportunities to users occurring during each of the segments may be associated with a particular specified experimental treatment. The short duration of the interval and segments may aid in reducing experimental bias by reducing variation in non-experimental variables between different treatment groups. User behavior following experimental treatment may be tracked and utilized in measurement of user response associated with the treatment. Results of the experiment may be utilized in optimizing aspects of an online advertising campaign.

International Classification:

G06F 15/173

US Classification:

709224

Abstract:

Methods and systems for determining the effect of a host on network latency while delivering online ads are disclosed. Observational test data relating to one or more network latency tests conducted on a plurality of hosts may be obtained. A first group and a second group of hosts may be created, wherein the first group includes the host and the second group doesn't include the host. At least one predetermined metric for each of the first group and the second group is computed based on the test data. A ratio of the at least one predetermined metric for the first group to the at least one predetermined metric for the second group is computed. The host may then be ranked based at least in part on the ratio.
