In one implementation, a method includes obtaining time series data. The time serious data includes a plurality of network utilization measurements. The plurality of network utilization measurements is indicative of a plurality of utilizations of one or more resources of a network resource at a plurality of times. The method also includes determining whether the time series data comprises a plurality of segments. Each segment of the plurality of segments is associated with a separate regression model and each segment includes a portion of the time series data. The method further includes identifying a current segment from the time series data when the time series data comprises the plurality of segments. The method further includes determining an estimated network utilization based on a current regression model associated with the current segment.

Estimating utilization of network resources using time series data

An example embodiment of the present invention provides a process for abstracting an implementation-independent model to an implementation-specific model during transformation in a MDA system. In the example embodiment, the MDA system comprises a transformation engine whose components might include software tools such as AndroMDA and Muse. The transformation engine accepts as input an implementation-independent model written in a modeling language such as UML that provides graphical notation to describe inheritable classes and their attributes and relationships. The transformation engine also accepts a configuration file which allows the designation of a class in the model as a manageable resource. From these inputs, the transformation engine creates a manageable resource corresponding to the class, which resource includes any subclasses by inheritance from the designated class unless the subclass is specifically excluded in the configuration file. In one embodiment, the manageable resources created by the transformation engine are WSMD manageable resources.
