An announcement protocol may allow disparate, and previously incompatible, content delivery network caches to exchange information and cache content for one another. Announcement data may be stored by the respective caches, and used to determine whether a cache is able to service an incoming request. URL prefixes may be included in the announcements to identify the content, and longest-match lookups may be used to help determine a secondary option when a first cache determines that it lacks a requested content.

Content delivery network routing using border gateway protocol

Aspects of the disclosure relate to transmitting content throughout a distribution network. For example, a computing device may generate data packets and attribute packets, and transmit the data packets and attribute packets to one or more user devices. The attribute packets may comprise information that enables validation and storage after the data packet is reassembled by the receiving device.

Systems and methods for content transmission

Methods and systems for managing data and transmission of content are disclosed. A computing device may receive a request for content. The computing device may determine data associated with the requested content.

Methods and systems for processing data requests

A method of data conditioning is disclosed that in one aspect can include the steps of receiving a data stream, encoding a time code in the data stream to identify a portion of the data stream corresponding to a content fragment, and separating the identified portion of the data stream to define the content fragment, wherein the content fragment comprises the encoded time code.

System and method for data stream fragmentation with scalability

Transaction activity of a cache maintaining content may be monitored to determine periods of transaction activity below a first threshold amount of transactions. A period of anticipated transaction activity above a second threshold amount of transactions may be determined. A period of anticipated transaction activity below the first threshold may be selected based upon the monitored periods of transaction activity below the first threshold and the determined period of anticipated transaction activity above the second threshold. Content then may be evicted from the cache during the selected period of anticipated transaction activity.

Cache eviction during off-peak transactions

Aspects of the disclosure relate to validation of a request for an asset based on information in the request. Validation of the request can be processed by a network node in a network repository that contains the asset. In one aspect, validation of the request can comprise determining if the request is legitimate based at least on processing at least a portion of the information in the request. In response to a legitimate request, the network node can process the request and, as a result, a data object associated with the asset can be supplied to a device originating the request. In the alternative, the network node can yield an exception.

Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, a system that monitors telemetry information may include a user that gathers telemetry information of a device and transmits the information to a monitored room. A manager may join a monitored room and monitor the monitored room for particular types of telemetry information. In one example, a manager may determine whether a downstream device is experiencing a network problem, such as a low bitrate. A manager may also transmit commands to the player via the monitored room, which causes the downstream device to operate in accordance with the transmitted command. In one example, a manager may transmit a command that causes a player to decode a particular service.

Monitoring and using telemetry data

Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, methods that monitor and use telemetry information may include receiving telemetry information relating to advertisements, whether the advertisement reporting is active, and/or whether thresholds associated with the output of advertisements have been satisfied. In some examples, telemetry information may be received via an application. In some examples, advertisments may be selected or generated for display based on analysis of the telemetry infomration. In some examples, commands may be transmitted to a device to initiate advertisement related reporting.
