Prevent cascade failures in computer systems

摘要

A computer hardware implemented method of preventing a cascading error in a complex data stream computer system, wherein a cascading error results in untrusted output from the complex data stream computer system, and wherein the computer hardware implemented method comprises: Receiving a first group of binary data identifying a plurality of subcomponents in a complex data stream computer system, the identified plurality of subcomponents having a plurality of upstream subcomponents and a downstream subcomponent; Receiving a second group of binary data identifying a plurality of outputs generated by the plurality of upstream subcomponents; Receiving a third group of binary data identifying multiple sub-component sub-inputs, wherein the identified multiple sub-component sub-inputs are the identified multiple outputs generated by the plurality of upstream sub-components, and wherein the identified multiple inputs are inputs to a sub-component downstream data processing process performed by the subordinate subcomponent; Generating accuracy values by computer hardware by assigning an accuracy value to each of the identified multiple outputs, the accuracy value describing a confidence level of accuracy for each of the identified multiple outputs, and wherein each of the identified multiple outputs is separated into separate upstream subcomponents of a separate upstream data processing process created by the several upstream subcomponents; Generating weighting values by the computer hardware by assigning a weighting value to each of the identified multiple inputs to the subordinate subcomponent, the weighting value describing a criticality level for each of the identified multiple inputs when executing the downstream data processing process in the subordinate subcomponent; and Using the accuracy values and the weighting values by the computer hardware to dynamically adjust which of the identified multiple inputs are input to the subordinate subcomponent until an output from the subordinate subcomponent corresponds to a predefined trustworthiness level.
