US Patent:

7974288, Jul 5, 2011
Filed:

May 15, 2009
Appl. No.:

12/467007
Inventors:

David Romrell - Hillsboro OR, US
Christopher Charles Ptacek - Beaverton OR, US
Assignee:

Barracuda Networks Inc - Campbell CA
International Classification:

H04L 12/56
US Classification:

370392, 3703953, 3703955
Abstract:

Data traffic is scheduled by, in a first scheduler, selecting a source of traffic from a plurality of sources of traffic, each source being associated with a second scheduler, in a second scheduler associated with the selected source of traffic, selecting a type of traffic from a plurality of types of traffic within the source selected by the first scheduler, and transmitting data of the selected type and source. Identifying and creating tunnels between endpoints in a network for optimum data traffic method and apparatus.

US Patent:

20210029416, Jan 28, 2021
Filed:

Oct 8, 2020
Appl. No.:

17/065950
Inventors:

- Suwanee GA, US
Christopher Ptacek - Beaverton OR, US
Zhan Hong Liau - Richmond Hill, CA
Bhavesh Patel - Mississauga, CA
Parasuram Ranganathan - Brampton, CA
Sean Michael Sheedy - Lake Oswego OR, US
International Classification:

H04N 21/81
H04N 21/435
H04N 21/858
H04N 21/2343
H04N 21/44
H04N 21/235
H04N 21/262
Abstract:

A method receives a manifest for video requested by a client device. The manifest including links for different versions of the video for the client device to use to request segments of the different versions of the video based on conditions detected by the client device. A placeholder in the manifest is selected based on a configuration specifying the placeholder as a trigger to insert alternate content into the manifest. The method then selects a metadata payload based on the configuration specifying the placeholder and a source of the metadata payload and dynamically inserts the metadata payload into the manifest at a position based on the placeholder. The metadata payload is added with an identifier from the configuration that identifies the metadata payload to the client device. The manifest is outputted with the metadata payload for use by the client device while playing the video.
