CCR-9877139 Berman该项目进行研究的设计，实施和算法的分析，以支持分布式网络中的可扩展和可靠的通信服务。 重点围绕影响国家网络通信基础设施的重要挑战以及越来越多的网络用户和服务的需求。 这些挑战包括：减轻网络流量日益减少的局部性对网络主干造成的压力，缓解增加大量地理上分散的网络主机的问题，采用容错和容错通信方法，以及将快速切换和移动的通信设备等各种技术纳入国家联网基础设施。 在应对这些挑战方面的一个重大障碍是在如此庞大且不断增长的全球网络中路由、交换、寻址和保证消息传递的困难。 这是一个基础和应用研究的计划，使用网络算法，计算组合学和图论技术攻击这些可扩展性和可靠性问题。 网络的拓扑结构和与网络路由方案相关的算法特性的分析将是主要的焦点。 将利用俄亥俄州超级计算机中心和OCARNet专用ATM研究网络提供的网络平台进行广泛的实施和实证研究。

CCR-9877139BermanThis project conducts research on the design, implementation, and analysis of algorithms for the support of scalable and reliable communication services in distributed networks. The focus centers around important challenges that affect the national network-communication infrastructure and the needs of increasing numbers of network users and services. These challenges included mitigating the stress on network backbone caused by the diminishing locality of network traffic, easing the addition of large numbers of geographically distributed network hosts, implementing fault-tolerant and congestion-tolerant communication methods, and integrating diverse technologies such as fast-switching and mobile communication devices into the national networking infrastructure. A significant obstacle in meeting these challenges is the difficulty of routing, switching, addressing, and guaranteeing delivery of messages in such a large and growing global network. This is a program of fundamental and applied research attacking these scalability and reliability problems using techniques of network algorithms, computational combinatorics and graph theory. The analysis of the topological structure of networks and the algorithmic properties associated with network routing schemes will be the primary focus. Extensive implementations and empirical studies building on the experience using the network platform provided by the Ohio Supercomputer Center and the OCARNet dedicated ATM research network will be performed.
