Method of distributed treating non-stationary flow of real-time applications in conditions of deficit in heterogeneous computer system resources

FIELD: physics.

SUBSTANCE: from the previous state of the art, the procedures of cluster analysis and determination of query classes, calculating the resource intensity of the query, assigning the request for processing were used. After the introduction of new procedures for setting the level of service quality, determining the computational complexity of the query, ordering queries in accordance with timeliness, it became possible to perform the operation of a heterogeneous computing system in the event of its overload.

EFFECT: increasing the likelihood of servicing requests in the conditions of a deficit in the computer system resources and the presence of denials in the servicing of applications by smoothing the flow of incoming applications by changing the parameters of the service request quality.

SUBSTANCE: invention relates to distribution of backup information across storage locations in a network-based backup architecture. Virtual layering of backup information across storage locations in the backup architecture can be implemented. Statistical models are used to dynamically re-allocate backup information among storage locations and/or layers to ensure availability of data, minimum latency upon restore and minimum bandwidth use upon restore. In addition, heuristics or machine learning techniques can be applied to proactively detect failures or other changes in storage locations such that backup information can be reallocated accordingly prior to a failure.
