International ClassG06F 013/362AbstractA computer system includes bus bandwidth management for operation of a high-speed bus. The high-speed bus is coupled to a plurality of modules. A plurality of client applications operate on the computer system, and request services from the high-speed bus to transfer data from a source module to at least one destination module. The bus bandwidth management system contains a bus manager, a dispatcher, a global controller, and a local controller contained on each module. Transfer requests for data transfer on the high-speed bus are made from the client applications to the bus manager. The bus manager takes the requested information and, based on a bus management policy management in effect, schedules a transfer order for the transfer requests. The bus manager then transfers the ordered transfer requests to the dispatcher. The dispatcher decomposes the ordered transfer requests into individual bus transfer operations. For each individual bus transfer operation, the dispatcher loads a command packet into the global controller, the source module, and the destination module(s). After the dispatcher dispatches all individual bus transfer operations, the dispatcher returns to the bus manager to receive the next transfer request. The global controller executes the individual bus transfer operations in the transfer order.Other References
