A performance assessment model for distributed software systems

In this research, a performance-engineered design framework that utilizes the system architecture and object-oriented software design techniques of the Unified Modeling Language (UML) and the architecture of the Hierarchical Performance Model (HPM) is developed to assist designers in developing and evaluating alternatives for performance assessment. Architectural, structural and behavioral components at various levels of abstraction are considered for performance model generation and evaluation. during the software design process. Performance Views for the presentation of performance information and selection of critical path scenarios are also described Throughout the paper, the author presents ways in which this framework supports current methods for the performance assessment of software architectures.
