  • Patent number: 9935994
    Abstract: A method, computer readable medium and apparatus for calculating a capacity for high speed packet access data in a link in a communications network are disclosed. For example, the method initializes parameters associated with streaming data, long elastic data and short elastic data, determines, via a processor, a capacity value such that a quality of service metric is met for the streaming data, the long elastic data and the short elastic data and provisions the link with the capacity value if the quality of service metric is met.

  • Patent number: 9807592
    Abstract: The increasing amount of internet traffic from video streaming services, in addition to users requesting more personalized content and creating/sharing video content, has led to a huge demand for highly scalable and efficient distribution of video content, especially with mobile computing devices. Embodiments provide a network and service infrastructure better suited to these video content distribution and mobility needs. More intelligence is provided in the network infrastructure through an awareness of the user status/activity, end-user device, and content characteristics in correlation with the network bandwidth conditions. In this view of adding more intelligence in the network, additional communication is utilized between the service platform and the network to identify content characteristics (e.g., video content, content encoding characteristics), network characteristics, and device characteristics.

  • Publication number: 20150195328
    Abstract: Technology to provide improved quality-of-experience-aware multimedia streaming is disclosed. Several types of communications that can be made between clients and servers are described. These communications enable improvements to current approaches that are used to achieve hyper-text transfer protocol (HTTP) adaptive streaming. These messages can be used in conjunction with computer circuitry configured to: determine a bandwidth available to the server for transmitting HTTP adaptive streaming content to a plurality of clients; receive HTTP requests from the plurality of clients for representations offered by the server in a manifest file for the HTTP adaptive streaming; and calculate an availability of each representation that is offered in the manifest file for the server. The availability can be calculated, at least in part, based on the determined bandwidth. The availability of each representation can be communicated from the server to the plurality of clients.
