ABSTRACT0306457New Mexico State UniversityCook, JonathanIn this age of information, computers have entered virtually every aspect of society and life, andthe future holds expectations of ubiquitous communicating computers, from the PDA-cellphones onthe belt, the desktops at work and home, the traveling laptop, and the smart car. In this alwaysnetworkedworld, it is to be expected that these systems will automatically receive and utilize software upgrades, new software applications, and the like. Today's software has taken the tentative first steps towards automatic, component-based software evolution, but in these mechanisms there is no real control over the evolving software components. Rather, users are quite familiar with the problems of mis-matched, wrongly timed changes in system components. Overcoming these problems will be crucial to developing the \always-on" future of ubiquitous computing. This project will take advantage of the rise in dynamic, distributed, component-based software architectures, and will pursue active techniques to help maintain reliability during system execution and throughout system evolution.Specifically, this research will investigate dynamically combining and controlling multiple versionsof components to increase the overall system reliability throughout its evolution. The goal is to provide a framework where component versions can be inspected, managed, and manipulated. Such a framework will allow new versions of components to be brought into a system to introduce enhancements, while still keeping older versions on-line to protect the system against accidental faults that break existing functionality. In addition, it will enable basic component management facilities that will allow self-checking of components and enable basic reasoning about the dynamic version dependencies that exist in the system.

在这个信息时代，计算机几乎已经进入了社会和生活的各个方面，未来人们期待着无所不在的通信计算机，从腰带上的PDA手机，工作和家庭的台式机，旅行笔记本电脑和智能汽车。在这个总是网络化的世界中，期望这些系统将自动接收和利用软件升级、新的软件应用等。今天的软件已经采取了试探性的第一步，自动，基于组件的软件演化，但在这些机制有没有真实的控制演变的软件组件。相反，用户非常熟悉系统组件中不匹配、错误定时的更改的问题。克服这些问题对于发展“永远在线”的未来无处不在的计算至关重要。本计画将利用动态、分散式、以元件为基础的软体架构的兴起，并将追求主动技术来协助维持系统执行期间与系统演化期间的可靠性，特别是探讨动态地结合与控制多个版本的元件，以增加系统演化期间的整体可靠性。其目标是提供一个框架，可以在其中检查、管理和操作组件版本。 这种框架将允许将新版本的组件引入系统以引入增强功能，同时仍然保持旧版本在线以保护系统免受破坏现有功能的意外故障。此外，它还将启用基本的组件管理设施，这些设施将允许组件的自我检查，并允许对系统中存在的动态版本依赖性进行基本推理。
