Admission control for aggregate data flows based on a threshold adjusted according to the frequency of traffic congestion notification
InactiveUS6839767B1Guaranteed bandwidthExacerbating congestion condition is avoidedError preventionTransmission systemsTraffic capacityData stream
An admission controller and its method of operation for controlling admission of data flows into an aggregate data flow are described. Admitted data flows are aggregated into an aggregate data flow for transmission by a router, for example, over a data network. The aggregate data flow typically follows a pre-established path through the network; for example a multi-protocol label switched (MPLS) path. The path has minimum and maximum bandwidth limits assigned to it. The admission controller controls admission of new data flows into the aggregate data flow by granting or denying new session requests for the new data flows. Congestion notifications received from the network and bandwidth limits of the path are considered in determining whether to grant or deny a new session request. In this way, the admission controller provides elastic sharing of network bandwidth among data flows without exacerbating network congestion and while remaining within the path's bandwidth limits. The data flows may include transaction oriented traffic.

Accounting allocation method
InactiveUS6014640AQuantity minimizationEasy and efficient implementationComplete banking machinesFinanceDistribution methodParallel computing
An expense allocation method utilizes matrix multiplication to transform a set of reciprocal or cascading allocation rules into a new set of one-step allocation rules. The new set of rules reallocates amounts directly to the ultimate destination without going through numerous intermediate levels of reallocation. By taking advantage of the specific structure of the matrix, and partitioning the matrix into four (4) subparts, the matrix multiplication process is greatly simplified. The expense allocation method can be easily and efficiently implemented on a computer system, including computers based upon parallel or vector architectures. This invention permits most allocation work to be done before the end of an accounting period, allowing end-of-period accounting work to be completed sooner. Alternatively, expenses can be allocated as they occur, rather than waiting until the end of a period.

A method and system is provided for doing compact disc TOC look-ups cheaply and efficiently by using a special indexing mechanism particularized to TOC look-ups. The indexing scheme allows a successful search of TOCs using as few as 2 disk seeks in contrast to the usual hundreds of disk seeks required by a general purpose indexing scheme. This performance improvement is achieved by using a static database of TOCs in a read-only implementation so that the data organization and code for lookups can be optimized without regard for any updates to this data at a later time. The index data structure is arranged in a fashion that allows for seek-less, linear scans of index information once the proper scan location in the index has been identified.
