基于DPWS的网络化并行结构的Scalability改进
Improving the Scalability of DPWS-Based Networked Infrastructures
摘要：
Web服务设备配置文件（DPWS）规范支持在各种设置中无缝发现、配置和互操作联网设备，从家庭自动化和多媒体到制造设备和数据中心。不幸的是，事件通知机制的简单性使其适合资源受限的设备，这使得它很难扩展到具有更严格可靠性要求的大型基础设施，具有讽刺意味的是，自我配置将是最有用的。在这份报告中，我们解决这一挑战的建议，以集成基于八卦的传播DPWS，从而保持与规范的原始假设的兼容性，并避免集中配置服务器或自定义黑盒中间件组件。详细地说，我们将展示我们的方法如何提供一个渐进的和非侵入性的解决方案，DPWS的可扩展性的限制，并通过实验评估它的实现基于Web服务的设备（WS4D）的Java多版本DPWS堆栈（JMEDS）。
英文摘要：
The Devices Profile for Web Services (DPWS) specification enables seamless discovery, configuration, and interoperability of networked devices in various settings, ranging from home automation and multimedia to manufacturing equipment and data centers. Unfortunately, the sheer simplicity of event notification mechanisms that makes it fit for resource-constrained devices, makes it hard to scale to large infrastructures with more stringent dependability requirements, ironically, where self-configuration would be most useful. In this report, we address this challenge with a proposal to integrate gossip-based dissemination in DPWS, thus maintaining compatibility with original assumptions of the specification, and avoiding a centralized configuration server or custom black-box middleware components. In detail, we show how our approach provides an evolutionary and non-intrusive solution to the scalability limitations of DPWS and experimentally evaluate it with an implementation based on the the Web Services for Devices (WS4D) Java Multi Edition DPWS Stack (JMEDS).
