虽然许多应用程序服务提供商已经提出使用瘦客户机计算在互联网上提供计算服务，很少的工作已经完成，以评估在广域网中的瘦客户机计算的有效性。为了评估瘦客户端计算在未来商品高带宽互联网接入背景下的潜力，我们使用了一种新颖的、非侵入性的慢动作基准测试技术来评估几种流行的瘦客户端计算平台在跨国家提供计算服务方面的性能通过Internet 2。我们的研究结果表明，在广域网环境中使用瘦客户端计算可以提供可接受的性能在Internet2，即使客户端和服务器位于数千英里以外的国家的两端。但是，不同瘦客户机平台的性能差异很大，并非所有平台都适合此环境。虽然许多瘦客户端系统被吹捧为带宽效率，我们表明，网络延迟往往是限制广域瘦客户端性能的关键因素。此外，我们表明，用于提高带宽效率的相同技术往往会导致广域网的整体性能较差。我们的特点和分析不同的设计选择在各种瘦客户端平台，并解释这些选择应选择支持广域计算服务。
While many application service providers have proposed using thin-client computing to deliver computational services over the Internet, little work has been done to evaluate the effectiveness of thin-client computing in a wide-area network. To assess the potential of thin-client computing in the context of future commodity high-bandwidth Internet access, we have used a novel, non-invasive slow-motion benchmarking technique to evaluate the performance of several popular thin-client computing platforms in delivering computational services cross-country over Internet2. Our results show that using thin-client computing in a wide-area network environment can deliver acceptable performance over Internet2, even when client and server are located thousands of miles apart on opposite ends of the country. However, performance varies widely among thin-client platforms and not all platforms are suitable for this environment. While many thin-client systems are touted as being bandwidth efficient, we show that network latency is often the key factor in limiting wide-area thin-client performance. Furthermore, we show that the same techniques used to improve bandwidth efficiency often result in worse overall performance in wide-area networks. We characterize and analyze the different design choices in the various thin-client platforms and explain which of these choices should be selected for supporting wide-area computing services.
