Abstract: Devices, systems and methods that measure at least one of the latency and the jitter experienced over a defined portion of a path between a sending device and a receiving device. A network monitoring unit is located between the sending and receiving devices, and monitors packets exchanged between the two to measure the latency and/or jitter.

Abstract: Devices, systems and methods that determine both the existence of, and location where, packets were dropped in transit between a sending device and a receiving device. A network monitoring unit is located between the sending and receiving devices, and monitors packets exchanged between the two to determine the location where packets were dropped.

Abstract: Devices, systems, and methods that identify and mark traffic intended to pass through a network with low latency relative to other traffic through the network. The devices, systems, and methods may include a first low latency DOCSIS (LLD) agent that identifies characteristics of low latency packets and/or a second LLD agent that uses the characteristics to identify low latency traffic and mark it for low latency treatment in the network.

Abstract: Systems and methods that adaptively grant amounts of bandwidth to a remote device for upstream transmissions. The systems and methods may adaptively grant a first amount of bandwidth during a first interval, and vary the amount of bandwidth proactively granted over subsequent intervals using a metric of usage of the proactive bandwidth granted.

Abstract: A method receives a manifest for video requested by a client device. The manifest including links for different versions of the video for the client device to use to request segments of the different versions of the video based on conditions detected by the client device. A placeholder in the manifest is selected based on a configuration specifying the placeholder as a trigger to insert alternate content into the manifest. The method then selects a metadata payload based on the configuration specifying the placeholder and a source of the metadata payload and dynamically inserts the metadata payload into the manifest at a position based on the placeholder. The metadata payload is added with an identifier from the configuration that identifies the metadata payload to the client device. The manifest is outputted with the metadata payload for use by the client device while playing the video.

Abstract: Systems and methods for providing a full reverse translating proxy for streaming media content, which can employ session tracking or transmuxing, or both. The described system can be integrated seamlessly into an existing adaptive streaming environment. The system can transmux each request from a client into a delivery format supported by an origin content server, and vice versa, irrespective of the specific delivery format used by either the client or server. Conversely, the system can further transmux the requested content into the delivery format used by the client. A stateful session model can link each request from a specific end user for a specific piece of content to a particular identified client streaming session.
