Abstract: Methods and apparatus for processing requests for content received from customer devices are described. A decision on how to respond to a request for content is made at an edge node based on a locally maintained popularity list. The local popularity list reflects the local popularity of individual pieces of content at the edge node. A white list of content to be cached and served irrespective of popularity is sometimes used in combination with the local popularity list to make decisions as to how to respond to individual requests for content. In some embodiments the edge node decides on one of the following responses to a content request: i) cache and serve the requested content; ii) serve but don't cache the requested content; or iii) redirect the content request to another node, e.g., an alternate serving node, which can respond to the content request.

Abstract: Encrypting data in a machine learning model is disclosed. Private data to be encrypted is identified. The private data is encrypted in a first trained machine learning model (MLM) by training an MLM with a decryption code to generate the first trained MLM, wherein the first trained MLM is trained to output the private data when provided, as input, the decryption code, but not output the private data if provided any other input.

Abstract: Multicast video program switching architecture. In one embodiment, a user makes a request for service. A controller determines whether the channel is currently broadcast. When the channel is currently broadcast, redirect the user to an address of the channel. When the channel is not currently broadcast, query a storage apparatus to find a currently broadcast channel that has no current viewership, send, a request to a multicast network address translation (MNAT) router comprising a multicast address of the currently broadcast channel and an identifier of the requested channel to modify MNAT settings on the MNAT router and redirect the user to the multicast address, the multicast address associated with the requested channel.

Abstract: A multi-tier content distribution system includes a first repository, a second repository, and a third repository from which to distribute content. The first repository serves as a first choice from which to distribute requested content to a requesting party. If the requested content is not available from the first repository, the multi-tier content distribution system attempts retrieval and distribution of the requested content from the second repository, which serves as a backup resource to the first repository. If the requested content is not available from the second repository, the multi-tier content distribution system attempts retrieval and distribution of the requested content from the third repository, which serves as a backup resource to the second repository. The multi-tier content distribution system includes a content management resource operable to selectively populate the second repository with pre-formatted content retrieved from the third repository.
