    摘要： Data may be transmitted in a broadcast mode to multiple devices operating in a network. Efficient utilization of bandwidth while providing a desired level of quality of service is enabled for the applications executing on the devices that utilize the broadcasted data. A set of bandwidth constraints may be utilized in combination with a set of heuristics and rules for the allocation and re-allocation of bandwidth among multiple applications in a manner that minimizes the impact on the quality of service metrics of importance to the affected applications when contention exists for the network resources. Quality of service provided to each application may be degraded smoothly, with certain priorities and guarantees being maintained. Event segmentation and reassembly functions for applications may be provided, as well as reliability mechanisms to increase the ability to provide data to client devices that have not been actively receiving for significant periods of time.

    摘要： Embodiments provide systems, methods, and computer program products for mapping higher-layer circuits, links, flows, and services to lower layer circuit and connection elements to determine utilization of the lower layer circuit elements based on the high-layer traffic. Higher layer configuration data and lower layer configuration data are imported to populate a model. An inter-layer relationship is either directly or indirectly mapped from the higher layers to the lower layer. Once the inter-layer relationship is established, the higher-layer circuits, links, flows, and services are inspected using the lower layer circuit and connection elements. Circuit and packet-based utilization is determined for the lower layer elements based on the higher-layer traffic flows.

    摘要： Datacasting systems may include one or more compound carousels each managing one or more elementary carousels, and managed by a bandwidth manager. Subsets of compounds carousels may be identified, for example, according to priority levels. Bandwidth allocations may be determined for the compound carousels. For example, the bandwidth manager may utilize multiple bandwidth allocation cycles to determine the bandwidth allocations. The multiple bandwidth allocation cycles may form a sequence. Each bandwidth allocation cycle may at least partially allocate an available datacasting bandwidth resource to at least one of the identified subsets of the compound carousels. The allocations may be based at least in part on desired bandwidths determined by the compound carousels and/or one or more bandwidth guidelines of datacast sessions associated with the compound carousels.

    摘要： A datacast system, and associated apparatus and method for automatically managing a data object or objects within a hierarchical carousel structure by enabling, among other functions, the dynamic allocation of bandwidth to each carousel within the structure. The dynamic bandwidth allocation enables a server platform to redistribute the bandwidth allocated to a carousel or set of data objects to adjust to desired changes in object transmission policies or priorities of a datacast application.

    摘要： Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.
