Open System Architecture

* Back Cover Architecting with RM-ODP is a comprehensive guide to the techniques for architecting a software system. An architect must address many complex challenges, ranging from business strategy related challenges to technology related challenges. Businesses are evolving from small, centralized, organizational endeavors to large, distributed, virtual enterprises with a multitude of endeavors. Concurrently, technologies supporting systems are evolving to support more autonomous ad distributed processing. Architecting a system for a business that meets the needs of today but is flexible enough to meet the needs of tomorrow requires a number of carefully made architectural decisions, such as: * Determining how to capture the business problem to be solved and relating this to an architectural specification * Creating specifications at the appropriate level of detail, and how to represent these through modeling tools such as UML * Ensuring conformance of the implementation to the specified architecture * Identifying ways of specific semantic behavior * Identifying ways to componentize elements of the architecture Architects of a system must address a number of technology related considerations as well. Among these are interoperability, interactions, policy driven execution, fault tolerance, quality of service, and federation. Patterns of reasoning, architectural patterns for defining a solution, for all of these considerations are found in this book. The International Standard Reference Model of Open Distributed Processing (RM-ODP) provides much in the way of fundamental concepts, rules, and patterns of reasoning for a software architecture of distributed systems. This book explores theuse of RM-ODP, augments that with best practices in industry and academia, and guides the reader to the strengths and weaknesses of RM-ODP. To be sure, RM-ODP is an internationally agreed upon methodology for clearly defining any architecture of a distributed system in an open manner.

HyperTransport™ (HT) technology promises to revolutionize connectivity for computers, servers, embedded systems, and networking and tele-communications equipment. It is a high-speed, low latency, point-to-point, packetized link that enables chips to transfer data at peak rates of up to 12.8 Gigabytes per second, far greater than existing bus technologies. Furthermore, HyperTransport improves reliability and reduces board design complexity. It is scalable and compatible with legacy PC buses, SNA, and PCI. "HyperTransport™ System Architecture provides a comprehensive, technical guide to HyperTransport technology. It opens with an overview of HT systems, highlighting the technology's fundamental principles, basic architecture, and its many advantages. The book goes on to detail all facets of HyperTransport systems, including the protocol, I/O, routing, configuration, and more. It also features important performance considerations and addresses critical compatibility issues. Essential topics covered include: Signal groupsPacket protocol, covering control and data packetsHT flow control, and how it differs from PCI flow controlI/O ordering rules, including upstream, downstream, and host ordering requirementsInterrupts, error detection, and error handlingHT system managementRouting packets, covering point-to-point topology and HT's fairness algorithmDevice configurationThe electrical environment, including power requirements and signaling characteristicsHyperTransport bridgesDouble-hosted chainsAnticipated networking extensionsPCI, PCI-X, AGP, and X86 compatibility issues A chapter is dedicated to transaction examples illustrating the practical application of HyperTransporttechnology. A MindShare PC System Architecture Series book, "HyperTransport™ System Architecture provides complete, authoritative, and detailed information necessary for developers, networking professionals, and anyone interested in implementing and deploying HT systems.

Open Architecture System Integration Strategy - In the late 1980s, Apple Computer was increasingly worried about the legion of graphical user interfaces about to be released that would compete with the Mac OS. In addition to improved versions of Microsoft Windows, which had previously been unsuccessful, they were now facing IBMs Presentation Manager, HP's NewWave, Sun Microsystems' OpenLook, and a host of other X11-based GUIs on various Unix platforms.

Open systems architecture - In telecommunication, the term open systems architecture means the layered hierarchical structure, configuration, or model of a communications or distributed data processing system that (a) enables system description, design, development, installation, operation, improvement, and maintenance to be performed at a given layer or layers in the hierarchical structure, (b) allows each layer to provide a set of accessible functions that can be controlled and used by the functions in the layer above it, (c) enables each layer to be implemented without ...

Open Services Architecture - The Open System Architecture (OSA) is part of the 3rd generation mobile telecommunications network or UMTS. OSA describes how services are architected in an UMTS network.

AMOS Operating System - AMOS is a small open source operating system currently for the x86 architecture.

Computer System Architecture - Computer System Architecture Computer architecture - In computer science, computer architecture is the conceptual design and fundamental operational structure of a computer system. It is a blueprint and functional description of requirements (especially speeds and interconnections) and design implementations for the various parts of a computer â€”focusing largely on the way by which the CPU performs internally and accesses addresses in memory. Open Architecture System Integration Strategy - In the late 1980s, Apple Computer was increasingly worried about the legion of graphical ...
