Abstract: Systems and methods are described for optimizing resource utilization in a communications network while also optimizing subscriber engagement with media content over the communications network. Requested content objects can be identified as delayable objects that can be queued for opportunistically delayed communication to both requesting and non-requesting subscribers. Queued delayed content objects are scored with an eye toward optimizing both subscriber engagement and utilization of opportunistically available communications link resources. For example, a storage manager calculates a likelihood that each subscriber will engage with the content if it is opportunistically delivered, and a scheduler calculates a priority order in which to queue each requested delayable content object.

Abstract: Embodiments provide efficient multicast handover for content delivery to client devices in multi-carrier communications systems. For example, client devices in a transport craft can consume a media channel offering via a first carrier during transport through the communications system. Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second.

Abstract: Storage decisions for a content cache determined for upgrades of renditions of a media object based on storage utility values for the renditions. The storage utility values for the renditions may be determined based on expected actions determined using delivery utility of renditions in a plurality of model scenarios. The storage values may also consider the behavior probability for user behaviors of the model scenarios. The rendition upgrade value for the rendition upgrades may be determined as the incremental storage value for a rendition upgrade per an incremental size for a rendition upgrade. By making storage decisions based on rendition upgrade values, the value of renditions stored in the content cache may be optimized.

Abstract: Described herein are ways to reduce bandwidth use for real-time broadcasts between an Internet Service Provider (ISP) and its subscribers by re-encoding audiovisual data streams to have a generic encoding that can be viewed by subscribers of different content providers. A system can determine that a plurality of subscribers is watching the same live event and can multicast the generic encoding of the live event to the plurality of subscribers, even where individual subscribers stream the live event from different content providers. This can eliminate the need for streaming multiple versions of the same live event from different content providers to subscribers. The systems can generically encode an audiovisual data stream of a live event to generate a single audiovisual data stream for the live event that is multicast to subscribers watching the same live event.

Abstract: Described herein are ways to advantageously reduce bandwidth use between an internet service provider and its subscribers by re-encoding media objects to have a generic encoding that can be cached at subscriber devices. When a subscriber makes an authorized request for a media object from a content provider, a cached version of the generically encoded media object may be played by the subscriber even if the subscriber is not a customer of the content provider that originally provided the media object. This can eliminate the need for streaming a new copy of the media object from the content provider. The disclosed systems are configured to identify when differently-encoded media objects represent the same media object so that subscribers can play cached media objects rather than requiring each media object be streamed from different content providers.

Abstract: Selection of a variant of a media object for delivery from a service provider to a user system using a delivery utility of available variants. The variants may each use different amounts of network resources. The delivery utility may be based on a network resource usage (e.g., a weighted network resource usage such as a provisioning cost value). The network resource usage may represent a cost to the service provider to transmit the variant. The delivery utility calculation may also be based on a predicted quality of experience for a variant. This may include a weighted probability of the quality of experience related to an effect of an adverse experience resulting from delivery of the variant (e.g., a churn cost value). The use of the delivery utility calculation may efficiently use communication network infrastructure to improve user quality of experience, server more users using given networking resources, or both.

Abstract: A media delivery system may obtain a manifest of a media object defining a plurality of renditions of at least one media element of the media object. Predetermined trimming rules may be applied to identify at least one rendition of a plurality of renditions of the at least one media element for removal from the manifest. The identified at least one rendition may be deleted from the manifest to generate a trimmed manifest. The media delivery system may deliver the trimmed manifest to a user system in operative communication with the shared communications channel of the media delivery system. In turn, removing renditions may facilitate efficiencies in relation to delivering the media object using the shared communications channel.

Abstract: Systems and methods are described for using opportunistically delayed delivery of content to address sub-optimal bandwidth resource usage in network infrastructures that allow subscribers to share forward link resources. According to some embodiments, content is identified as delayable and assigned to a delaycast queue and/or service flow. For example, a server system of a satellite communications system identifies content that can be delayed to exploit future excess link capacity through multicasting and to exploit subscriber-side storage resources. Some implementations attempt to exploit any excess link resources at any time, while others exploit unused bandwidth only during certain times or when a certain threshold of resources is available. Various embodiments also provide content scoring and/or other prioritization techniques for optimizing exploitation of the delaycast queue.

Abstract: Described herein are systems and methods that dynamically manage network traffic for individual subscribers based on past and current data usage rates. The disclosed systems and methods operate to control data traffic for a group of subscribers that share a common access network or that share a common access link to an access network. Prior to an individual subscriber reaching their data plan limit, the disclosed systems and methods track individual subscribers' past and current data rates and manage individual subscribers' current usage rates so that each subscriber's continually or periodically updating past usage rate stays within a provisioning rate for the group. This can improve user experience because rather than waiting until a subscriber has reached their plan data limit to impose strict data usage restrictions, the disclosed systems and methods use modest restrictions continuously or intermittently during the plan period.

The processor may also be configured to train a surrogate model using at least the simulated data to approximate the digital system model of the system and generate, using the trained surrogate model, estimated values for conditions or parameters of the systems based on operational data, wherein the operational data includes sensor data or in-service data from the system. Further, the processor may be configured to execute the digital system model of the system to generate simulation data based on the operational data and the estimated values or parameters generated by the surrogate model and synchronize or update a digital twin of the system based on the simulation data, wherein the digital twin represents a state or condition of the system.
