摘要

Methods and systems are described for managing blackout restrictions. A user device may retrieve a blackout condition from a blackout device. The blackout device may be a node in plurality of blackout nodes. Each of the blackout nodes may store blackout conditions for different corresponding content. The user device may retrieve the blackout condition from a blackout device associated with content in response to a request for the content. The user device may determine whether information associated with the user device satisfies the blackout condition. If the information satisfies the blackout condition, the requested content may be blocked. Alternative content may be output instead of the requested content.

說明書

The plurality of connections may comprise persistent connections. As a non-limiting example, a persistent connection may be a network communication channel that remains open for additional requests and responses rather than closing after a single exchange. The blackout condition (e.g., restriction condition, access condition) may be received via a persistent connection. A state (e.g., open state) of the persistent connections may not depend on a number of transactions (e.g., request and response), a state of a transaction, and/or a quality of a transaction. For example, the persistent connections may remain in an open state despite packet loss. The persistent connections may remain in an open state until the user device sends an instruction to close the persistent connections (e.g., or until a failure of the persistent connections, such as a failure of an underlying protocol such as transmission control protocol). The persistent connections may be configured to allow the user device and the blackout information server to transmit data at any time (e.g., if the persistent connection is operational). The persistent connections may be configured to remain in an open state after an initial transaction (e.g., a request is received and/or after a response is transmitted to the initial request). The initial transaction may be after the persistent connections are established (e.g., via exchange of an opening handshake). The persistent connections may not have a limit on the number of requests (e.g., transactions, responses). The persistent connections may not automatically be closed after a request is fulfilled. The persistent connections may remain in an open state without requiring an instruction to keep the persistent connections open. The persistent connections may remain in an open state without requiring a request or response to be pending. The persistent connections may be established based on an upgrade handshake from hypertext transfer protocol. The persistent connections may comprise a websocket connection to the blackout information server. The blackout information server may be queried via the persistent connections (e.g., a websocket connection, a websocket session).
