Abstract
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.
