TL;DR: A process to derive a reference architecture for a domain and the mapping of this reference architecture to the architectures of three open source Web servers, which is a relatively new domain is presented.
Abstract: A reference software architecture for a domain defines the fundamental components of the domain and the relations between them. Research has shown the benefits of having a reference architecture for product development, software reuse and maintenance. Many mature domains, such as compilers and operating systems, have well-known reference architectures. We present a process to derive a reference architecture for a domain. We used this process to derive a reference architecture for Web servers, which is a relatively new domain. The paper presents the mapping of this reference architecture to the architectures of three open source Web servers: Apache (80KLOC), AOL-Server (164KLOC), and Jigsaw (106KLOC).

TL;DR: Results obtained have shown that such an approach for supporting the CPPS design activity makes stakeholders aware of their decision consequences and is useful in practice, which can lead the way for the development and integration of such knowledge-based decision-making approaches within state-of-the-art digital factory and Computer Aided Engineering Design (CAED) tools.

TL;DR: A new technique is proposed that minimizes visual clutter for multiple, overlapping areas for large diagrams, yet preserves the diagram layout familiar to designers of complex, real-world systems.
Abstract: Understanding complex software systems requires getting insight in how system properties, such as performance, trust, reliability, or structural attributes, correspond to the system architecture. Such properties can be seen as defining several 'areas of interest' over the system architecture. We visualize areas of interest atop of system architecture diagrams using a new technique that minimizes visual clutter for multiple, overlapping areas for large diagrams, yet preserves the diagram layout familiar to designers. We illustrate our proposed techniques on several UML diagrams of complex, real-world systems.

TL;DR: In this paper, a Transparent Network Computing extension to a highly available version of UNIX System V Release 4.2 is presented to provide a higher degree of availability to I/O devices by providing for the takeover of their controlling entity.
Abstract: A system area network computer system architecture is structured as a single system image cluster operating system to offer an opportunity to increase the availability to I/O devices in the system. The computing system comprises a number of processor units coupled to a plurality of input/output (I/O) elements by a routing fabric that provides each of the processor elements with access to any one of the I/O elements. Using a Transparent Network Computing extension to a highly available version of UNIX System V Release 4.2, the system provides a higher degree of availability to I/O devices by providing for the takeover of their controlling entity.
