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

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

A computing platform executing an application may receive a response to a request for opening a network port for utilization by the application from a computing platform distinct from the computer platform executing the application. The computing platform executing the application may determine whether to open the network port for utilization by the application based on the response to the request. In some embodiments, the application may invoke at least one call to an application program interface (API) of an operating system (OS) running on the computing platform executing the application, and the request may be generated responsive to the at least one call to the API of the OS.

Application port management

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

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.

Self-validating data object locator for a media asset

Methods and systems for routing data are disclosed. In one aspect, service management can be implemented on one or more computing devices located between at least one router and one or more nodes. The one or more computing devices can be a default gateway for a plurality of user devices. In another aspect, the disclosed methods and systems can use a tag in routing a data block (e.g., service data) via a predefined route. For example, a device can transmit a request for a tag to a network node for routing a data block via a predefined route. Upon receiving the request, the network node can allocate a tag and create an interface. The interface can be associated with the tag and communications between the network node and the device for routing the data block.

Systems and methods for routing data

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.
