Collaborative Research: Middleware Support for Multicast Data Dissemination

该提案是匹兹堡大学和凯斯西部储备大学的合作提案。该提案计划探讨基本问题和相关的中间件开发问题，以支持广播和组播数据传播。当许多人试图访问相同的信息时(例如，选举期间的新闻网站)，服务器经常不堪重负，导致长时间的延迟。如果整个互联网上存在有效的多播功能，一台服务器就可以处理所有请求，既节省了计算机功率，又减少了总的互联网通信量。该方法将突出最先进的差距，并将研究和探索新的技术和算法。目标包括1.透明地为应用程序提供数据管理服务，如缓存、调度和一致性维护；2.提高互联网功能、性能和成本效益；3.减少应用程序开发时间，同时提高性能和可靠性。提案计划将信息和开发的软件提供给

The proposal is a collaborative proposal involving University of Pittsburgh & Case Western Reserve University. The proposal plans to explore fundamental questions and associated middleware development issues to support broadcast and multicast data dissemination. When many people try to access the same information (for example, news sites during the Election), servers are often overwhelmed resulting in long delays. If an effective multicast capability existed across the Internet, a single server could have served all the requests, saving both computer power as well as reducing the amount of overall Internet traffic. The approach will highlight gaps in the state-of-the-art and will research and explore new techniques and algorithms. The objectives include1. transparently provide applications with data management services such as caching, scheduling and consistency maintenance, 2. improve internet functionality, performance, and cost-effectiveness, and3. reduce the application development time while improving performance and reliability.The proposal plans to make the information and developed software available to
