Architectural level analysis of a software system for its quality attributes is a proven cost-effective approach. This is particularly significant for performance, which defines m...
The paper presents a hierarchical modeling approach of the N version programming in a real – time environment. The model is constructed in three layers. At the first layer we d...
Traditional agreement-based Byzantine fault-tolerant (BFT) systems process all requests on all replicas to ensure consistency. In addition to the overhead for BFT protocol and sta...
—The class of modern datacenters recently coined as “warehouse scale computers” (WSCs) has traditionally been embraced as homogeneous computing platforms. However, due to fre...
Quantitative prediction of quality properties (i.e. extrafunctional properties such as performance, reliability, and cost) of software architectures during design supports a syste...
