Framework for Designing, Evaluating, and Deploying Global-scale Adaptive Networked Systems

国家科学基金分布式系统研究CISE/ cnsabstract申请号：项目名称：设计、评估和部署全球规模自适应网络系统框架目前，设计和构建网络和分布式系统仍然充满了困难。然而，随着世界上越来越多的基础设施依赖于网络系统，解决这些挑战变得越来越重要。网络系统面临的挑战包括故障、系统组件之间缺乏命运共享、高度可变的通信模式、竞争条件、难以重现错误、异步、安全问题等。虽然Java等高级编程语言的出现提高了抽象级别，减轻了这种负担，但大多数程序员仍然面临着重新发明适当的技术来处理异步、容易发生故障的网络环境的任务，这些环境只有少数精英程序员知道。本提案旨在探索一种高级语言和运行时环境的设计和实现，用于构建和操作健壮的、高性能的、高可用的全局规模分布式系统。目标应用包括互联网规模的路由协议、行星规模的网络试验台和计算网格。这项工作旨在全面支持从设计到部署和操作的整个分布式系统生命周期。这项工作的总体目标是在以下方面实现质的转变：i)构建、调试和部署健壮的分布式系统所需的时间，ii)将高级策略转换为低级系统规范和配置的便利性和准确性，以及iii)以公平和一致的方式比较竞争系统架构的效用的能力。Brett D. fleisch博士CISE/ cns2004年6月29日项目主任。

National Science FoundationDistributed Systems Research CISE/CNSABSTRACTPROPOSAL NO.: 0411307PRINCIPAL INVESTIGATOR: Vahdat, Amin MINSTITUTION: University of California, San DiegoPROPOSAL TITLE: Framework for Designing, Evaluating, and Deploying Global-scale Adaptive Networked SystemsToday, designing and building networked and distributed systems remains fraught with difficulty. Yet, addressing these challenges is becoming increasingly important as an ever larger fraction of the world's infrastructure comes to rely upon networked systems. Challenges faced by networked systems include failures, lack of fate-sharing among sys-tem components, highly variable communication patterns, race conditions, difficulty in reproducing bugs, asynchrony, security concerns, etc. While the advent of higher-level programming languages such as Java has raised the level of abstraction and eased this burden, most programmers still face the task of reinventing the appropriate techniques for dealing with asynchronous, failure-prone network environments known by a handful of elite programmers.This proposal is exploring the design and implementation of a high-level language and runtime environment for building and operating robust, high-performance, and highly-available global-scale distributed systems. Target applications include Internet-scale routing protocols, planetary-scale network testbeds, and computational Grids. This work aims to holistically support the entire distributed system life-cycle from design to de-ployment and operation. The overall goals of this work are to effect a qualitative shift in: i) the time required to build, debug, and deploy robust distributed systems, ii) the ease and accuracy of translating high-level policy to low-level system specifications and con-figurations, and iii) the ability to compare the utility of competing systems architectures in a fair and consistent manner.
