This paper presents a characterization of broadband user behavior from an Internet Service Provider standpoint. Users are broken into two major categories: residential and Small-Office/Home-Office (SOHO). For each user category, the characterization is ...
Fine grain performance evaluation of e-commerce sites
E-commerce sites are still a reference for the Web technology in terms of complexity and performance requirements, including availability and scalability. In this paper we show that a coarse grain analysis, that is used in most performance studies, may ...
Ranking configuration parameters in multi-tiered e-commerce sites
E-commerce systems are composed of many components with several configurable parameters that, if properly configured, can optimize system performance. Before upgrading existing systems to overcome performance bottlenecks, several areas of a site's ...
Assessing the scalability of component-based frameworks: the CADENUS case study
This paper proposes an approach to scalability analysis of component-based systems. A theoretical model of the orchestrated behavior of a system's components is developed and potential bottlenecks are identified. The model is derived by performing an ...
A recursive random search algorithm for network parameter optimization
This paper proposes a new heuristic search algorithm, Recursive Random Search(RRS), for black-box optimization problems. Specifically, this algorithm is designed for the dynamical parameter optimization of network protocols which emphasizes on obtaining ...
