    摘要： A backbone service exposes network parameters, such as a minimum available bandwidth, latency, or packet loss, in a tunnel path between any source-destination pairs. The network parameters can be mapped as a function of time so that service teams can schedule when to use the backbone with minimized interruption to other users. The data generated by the backbone service can be transmitted, stored or displayed for informational purposes to provide insights to service teams on how to better leverage the network and create awareness of the current status of the backbone. The backbone service can be extended to provide bandwidth brokerage for controlling traffic distribution in the network. The backbone service can further provide triggered messages that inform service teams about failures in the network that could reduce the available bandwidth. The messages can further target users of affected source-destination pairs.

    摘要： Techniques are described for reducing the delay between the live playhead of live streaming content and the client playhead of a client device consuming the live stream. In one technique, an increased playback speed is used by the media player on the client device so that the delay is gradually reduced. In another technique, the media player jumps forward in the stream, skipping content identified as expendable.

    摘要： A system for delivering live streaming content based on accurate media data fragment size and duration. The system may include a client media player to receive a portion of a streaming media file (e.g., in an MP4 format), download a first sub-portion of the streaming media file including fragment-level metadata, and parse and analyze the fragment-level metadata to determine a size and duration of a current fragment of the media file. A media server may generate custom data identifying a size and duration of a current fragment of a media file. The media server may insert the custom data (e.g., as a custom header or unique packet identifier) and send the custom data to a client media player. The client media player may be configured to decode the custom data and determine the current fragment size and duration.
