Abstract
A system, apparatus, and method for transmitting data in a broadcast mode to multiple devices operating in a network. The invention enables the efficient utilization of bandwidth while providing a desired level of quality of service for the applications executing on the devices that utilize the broadcasted data. The invention utilizes a set of bandwidth constraints 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. The present invention implements processes to cause the quality of service provided to each application to degrade smoothly, with certain priorities and guarantees being maintained. The present invention also provides event segmentation and reassembly functions for applications, and includes reliability mechanisms to increase the ability to provide data to client devices that have not been actively receiving for significant periods of time.
