The focus of this proposal is the design and implementation ofcluster-based electronic commerce servers (or simply distributede-commerce servers) that are efficient, scalable, and capable ofservice differentiation. To achieve these properties, our serverswill efficiently adapt their quality of service, will efficientlyhandle any type of incoming request according to the client's profile,will not involve any centralized resources, and will cache both staticand certain dynamic content. The key challenges are in determiningthe set of policies and mechanisms that should be used todifferentiate the services provided and to implement truly efficientand scalable policies and mechanisms for request processing. At theend of the project, we will demonstrate two distributed e-commerceservers (an on-line store and an auction server) running on a clusterwith 64 processors.The contributions of this project will be the following: (1) Acomplete and general characterization of e-commerce workloads; (2) Anunderstanding of the issues involved in service differentiation fordistributed e-commerce servers, including the use of optimizationsbased on the past history of actions taken by high-priority clients;(3) The design, implementation, and evaluation of mechanisms forshared state maintenance and transaction support in distributede-commerce servers; and (4) The study of techniques and mechanisms forimproving the efficiency and scalability of distributed e-commerceservers.We believe that the potential implications of our research andcontributions are far reaching. In fact, we think that the impact ofour research can be substantial, given how significantly variouscompanies have come to rely on their on-line networking operations.Furthermore, our research can be useful for operating systems anddistributed systems teaching purposes, as our software infrastructurewill provide a tool for the study of distributed e-commerce servers.

该提案的重点是基于集群的电子商务服务器的设计和实施，这些服务器（或简单地分发了商务服务器）是有效，可扩展且能够提供服务差异化的。 为了实现这些属性，我们的服务器设备有效地调整了其服务质量，将根据客户的个人资料有效地授予任何类型的传入请求，不会涉及任何集中资源，并且会静态地缓解静态和某些动态内容。 关键挑战在于确定应使用的一组政策和机制，以分辨提供的服务，并实施真正有效的可扩展策略和请求处理的机制。 在该项目的结构上，我们将演示两个分布式的电子交换器（一个在线商店和一台拍卖服务器），并在Cluster-64处理器上运行。该项目的贡献将如下：（1）（1）电子商务工作负载的Ac-Romplete和一般表征； （2）对服务区分涉及的问题的弥补，供电的电子商务服务器，包括在高优先级客户所采取的行动的过去历史上使用优化的问题；（3）（3）对分布式交易商业服务器中的设计，实施和评估的设计，实施和评估； （4）对分布式电子交换器的效率和可扩展性的技术和机制的研究。我们相信，我们的研究和贡献的潜在影响已达到远处。 实际上，我们认为，考虑到各种各样的人如何依赖其在线网络运营，我们的研究的影响可能很大。FURTHERMORE，我们的研究对操作系统和分布式系统的教学目的可能很有用，因为我们的软件基础设施将为分布式电子商务服务器的研究提供一种工具。
