  • Publication number: 20180343133
    Abstract: A content distribution network includes first and second controllers, and multicast enabled routers. The first controller is configured to select a multicast channel for distributing content, to determine that the content has a geographic restriction associated with a restricted area in the content distribution network, to link an exclusion policy for the content to the multicast channel while the multicast channel provides the content, and to deny a request for the content from a client system within the restricted area based on the exclusion policy. The second controller is configured to distribute the exclusion policy to the multicast enabled routers including a first router configured to store the exclusion policy, and to ignore a multicast join message from the client system within the restricted area based on the exclusion policy.

  • Publication number: 20180234369
    Abstract: Aspects of the subject disclosure may include, for example, receiving an image, delivery instructions, and metadata associated with the image from a first device associated with a first user. The delivery instructions indicate to deliver the image to a second device associated with a second user, and the delivery instructions comprise security features and the metadata comprises a plurality of security preferences for delivery. Further, the plurality of security features and the plurality of security preferences are implemented on the image. In response to determination of a security risk due to the implemented security features or security preferences, the image is not delivered to the second device and a message is delivered to the first device indicating that the image was not delivered. Other embodiments are disclosed.

  • Publication number: 20180048525
    Abstract: Systems, methods and computer readable media are provided to control anycast traffic using a software defined network controller. Telemetry and event data is gathered from a plurality of service nodes in the network. The telemetry and event data sent by an event broker to an analytic application with a resource conditions at each of the plurality of service nodes is determined based on the telemetry and event data. Traffic routing change recommendations are provided to a software defined network controller based on resource conditions at each of the plurality of service nodes and a set of predetermined policies.

  • Publication number: 20170295030
    Abstract: A system for delivering content over a network includes a server. The server is configured to divide the content into multiple segments, to create multiple data streams using the segments of the content, and to transmit each of the data streams via a respective multicast session, wherein a copy of each of the multiple segments is transmitted during a single time slot of the multicast session.

  • Publication number: 20170078441
    Abstract: A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.

  • Patent number: 9531774
    Abstract: A system for providing multicast distribution of incrementally enhanced content is disclosed. The system may include encoding content by utilizing an incremental layer encoding algorithm to generate a low resolution base stream for content and one or more incremental streams for the content. The incremental streams may each have higher resolutions than the base stream. The system may provide the base streams and one or more of the incremental streams to a client device based on available bandwidth and based on the capabilities of the client device. Each of the streams of content may be provided to the client device by having the client device connect to one or more multicast sessions. As the streams are accessed by the client device, the client device may combine and decode the base streams, along with any accessed incremental streams, to obtain the content at an available resolution.
