Abstract:
Approximation techniques based on the theory of queueing networks are developed, including the approximate formulation of the MVA method (single-class and multi-class models) for fixed and variable service rates, hierarchical modeling based on flow equivalence (definition of flow-equivalent servers), bounds on performance (asymptotic bounds and balanced-systems bounds), bottleneck analysis. Examples of approximate methods for the analysis of non product-form systems are described, such as systems with memory/population constraints, blocking systems, priority systems (SWIC method), Fork-Join systems, etc. Reference is made to the development of models for Web-based systems, with emphasis on particular features such as load burstiness, the existence of proxying, caching, mirroring etc.
