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.

该提案的重点是设计和实现基于集群的电子商务服务器（或简称分布式电子商务服务器），该服务器高效、可扩展且能够提供服务差异化。 为了实现这些属性，我们的服务器将有效地调整其服务质量，将根据客户端的配置文件有效地处理任何类型的传入请求，不会涉及任何集中资源，并将缓存静态和某些动态内容。 关键的挑战在于确定一组策略和机制，这些策略和机制应用于区分所提供的服务，并实施真正高效且可扩展的请求处理策略和机制。 在项目结束时，我们将演示在具有 64 个处理器的集群上运行的两个分布式电子商务服务器（在线商店和拍卖服务器）。该项目的贡献如下：（1）电子商务工作负载的完整和一般特征； (2) 了解分布式电子商务服务器的服务差异化所涉及的问题，包括使用基于高优先级客户端过去的操作历史的优化；(3) 分布式电子商务服务器中共享状态维护和交易支持机制的设计、实现和评估； （4）研究提高分布式电子商务服务器的效率和可扩展性的技术和机制。我们相信我们的研究和贡献的潜在影响是深远的。 事实上，我们认为，考虑到各个公司对在线网络操作的依赖程度，我们的研究影响可能是巨大的。此外，我们的研究可用于操作系统和分布式系统教学目的，因为我们的软件基础设施将为研究分布式电子商务服务器提供工具。
