Abstract
A system includes a resource manager that provides unenforced allocation of streaming I/O bandwidth from streaming I/O bandwidth providers (e.g., CPU, disk, etc.) to streaming I/O bandwidth consumers (e.g., software application, television, etc.). Unenforced allocation denotes that bandwidth allocation in response to a consumer request is not guaranteed, nor is a consumer guaranteed that, once bandwidth has been allocated, it will not be de-allocated and reclaimed by the resource manager for allocation to another bandwidth consumer, based on a priority assigned to the bandwidth consumers.A bandwidth manager is included in a streaming I/O bandwidth provider that provides unenforced allocation from that particular provider to streaming I/O bandwidth consumers, in the same manner as the resource manager described above.Adaptive applications (consumers) are described which can submit a modified request for less provider bandwidth from a bandwidth provider if an initial request for bandwidth is denied by the consumer. The adaptive application can operate adequately, if not optimally, on the lesser amount of bandwidth, if it is allocated.
