Abstract: A technology for content delivery is provided. In one example, performance of a caching network, performance of a delivery network, and customer demand are modeled. Instructions are provided for a client device on how to request content based on the modeled performance of the caching network, the modeled performance of the delivery network and the modeled customer demand.

Abstract: Techniques are described for facilitating the delivery of digital content using gossip protocols. A group of client devices share information about network conditions in sideband communications using a gossip protocol. Each of the client devices then uses this information to make decisions about how to access content. By providing accurate and current information about network conditions the occurrence of buffering events and/or fatal errors may be significantly reduced or eliminated.

Abstract: A top-level service executes a procedure call to at least one dependent service to determine an entitlement result for a user device making a request of the top-level service. A processing device generates an entitlement token comprising the entitlement result, encrypts the entitlement token and sends the entitlement token to the user device. The user device can return the entitlement token when making additional requests of the top-level service to prevent the top-level service from having to make additional procedure calls to the at least one dependent service.

Abstract: Techniques are described by which decryption key rotation may be accomplished to support the protection of live streaming content. During playback of content using a decryption key, the client begins acquisition of a second stream of the same content (including a new decryption key) such that the client can transition playback of the content from the first stream to the second with few or no visible artifacts from the viewer's perspective.
