PREDICTIVE MODELS OF FILE ACCESS PATTERNS BY APPLICATION AND FILE TYPE

摘要

The speed at which files can be accessed from a remote location is increased by predicting the file access pattern based on a predictive model. The file access pattern describes the order in which blocks of data for a given file type are read by a given application. From aggregated data across many file accesses, one or more predictive models of access patterns can be built. A predictive model takes as input the application requesting the file access and the file type being requested, and outputs information describing an order of data blocks for transmitting the file to the requesting application. Accordingly, when a server receives a request for a file from an application, the server uses the predictive model to determine the order that the application is most likely to use the data blocks of the file. The data is then transmitted in that order to the client device.

1. A computer-implemented method comprising:
receiving access data from client devices of file accesses by applications to requested files, each instance of access data from a file access indicating a requested file, an application accessing the requested file, a file type of the requested file, and a respective order of access by the application of data blocks within the requested file; analyzing the received access data to identify an access pattern for a combination of an application and a file type; creating a model of the access pattern for a combination of the application and the file type, the model indicating a predicted order of access of data blocks of a file by the application; and responsive to a subsequent request received from a given application for a file of a given file type,
determining from the model for the combination of the given application and the given file type, a predicted order of access of data blocks of the file by the given application, andserving data blocks from the file to the given application according to the predicted order.
