The adaptive bandwidth throttling system implements a graceful diminution of services to the clients by delaying a first class of services provided by a network server in response to the effective bandwidth utilized by this network server exceeding a first threshold. If the demand for the bandwidth by this network server exceeds a second threshold, the bandwidth throttling system escalates the throttling response and blocks the first class of services from execution and can also concurrently delay execution of a second class of services. The implementation of the throttling process can be varied, to include additional levels of response or finer gradations of the response, to include subsets of a class of services. In addition, the threshold levels of bandwidth used to trigger the throttling response can be selected as desired by the system administrator.

The invention claimed is: 1. One or more non-transitory computer-readable media having stored thereon a plurality of instructions that, when executed by one or more processors of a computer, cause the one or more processors to: generate a bandwidth value indicating an average bandwidth used by a server to perform previous server operations; receive a request for the server to perform an additional server operation; compare the bandwidth value to a threshold; and restrict the request in a first manner if the bandwidth value exceeds the threshold. 2. One or more non-transitory computer-readable media as recited in claim 1, wherein the previous server operations and the additional server operation include one or more of read operations, write operations, and transmit operations. 3. One or more non-transitory computer-readable media as recited in claim 1, wherein to restrict the request in the first manner is to delay the request. 4. One or more non-transitory computer-readable media as recited in claim 1, wherein to restrict the request in the first manner is to block the request. 5. One or more non-transitory computer-readable media as recited in claim 1, wherein to restrict the request in the first manner is to prevent the request from entering a request queue of the server. 6. One or more non-transitory computer-readable media as recited in claim 1, wherein to receive the request is to receive the request into an asynchronous thread queue. 7. One or more non-transitory computer-readable media as recited in claim 1, wherein to restrict the request in the first manner is further to determine the first manner based at least in part on a size of the data involved with the request. 8. A method comprising: operating on a host computer system a bandwidth throttling system to allocate bandwidth to network servers executing on the host computer system as a function of system administrator defined thresholds via operations comprising: generating a value indicating a bandwidth used by a first server to perform previous server operations; receiving a request for the first server to perform an additional server operation; and restricting the request in a first manner if the value exceeds a first threshold but does not exceed a second threshold, and restricting the request in a second manner if the value exceeds the second threshold. 9. The method as recited in claim 8, wherein the first manner comprises delaying the request. 10. The method as recited in claim 8, wherein the second manner comprises blocking the request. 11. The method as recited in claim 8, wherein the restricting the request in the first manner comprises preventing the request from being presented to the first server. 12. The method as recited in claim 8, wherein the restricting the request in the first manner comprises preventing the request from entering a request queue of the first server. 13. The method as recited in claim 8, wherein the value indicates an average bandwidth used by the first server. 14. The method as recited in claim 8, wherein receiving the request comprises receiving the request into an asynchronous thread queue. 15. The method as recited in claim 8, wherein restricting the request in the first manner further comprises determining the first manner based at least in part on a size of the data involved with the request, and wherein restricting the request in the second manner further comprises determining the second manner based at least in part on the size of the data involved with the request. 16. A host computer system comprising: a processor; a memory operably coupled to the processor for execution of an adaptive bandwidth throttling system, wherein the adaptive bandwidth throttling system comprises a hierarchical bandwidth throttling system operating on the host computer system to allocate bandwidth to a plurality of network servers also executing on the host computer system, the allocating being performed as a function of system administrator defined thresholds via operations comprising: generating a value indicating a bandwidth used by a first server to perform previous server operations; receiving a request for the first server to perform an additional server operation, wherein the additional server operation comprises a server operation of a first class; and restricting the request in a first manner if the value exceeds a first threshold but does not exceed a second threshold, and restricting the request in a second manner if the value exceeds the second threshold while concurrently restricting another request for the first server to perform another server operation, wherein the additional server operation comprises a server operation of a second class.
