U.S.-Italy Cooperative Research: Integrated Voice, Data and Video Communications on High Speed, Fiber Optics Networks

该奖项将支持加州大学洛杉矶分校的Mario Gerla教授与意大利米兰理工大学的Luigi Fratta教授的一项研究合作。提议者打算把重点放在高速网络的设计上。光纤、信号处理和交换技术的进步、微型计算机和工作站的普及以及终端用户的日益复杂化，为向商业和住宅引入增强的通信服务提供了新的机会。提出了城域网的主要研究方向：城域网体系结构的设计与评价；宽带isdn性能评估与拓扑配置；局域网、城域网和b - isdn的互连。将研究基于树形拓扑和波分复用的新型城域网架构，目标是实现比现有城域网产品更高的速度（在千兆范围内）。高速广域网的网络控制和管理技术将得到发展，以保证效率和防止拥塞。

This award will support Professor Mario Gerla of the University of California at Los Angeles in a research collaboration with Professor Luigi Fratta of the Politechnical University, Milan, Italy. The proposers intend to focus on the design of high speed networks. The advances in fiber optics, signal processing and switching technologies, the proliferation of microcomputers and workstations and the increasing sophistica- tion of the end user offer new opportunities for the introduction of enhanced communications services to business and residences. The following main directions of research are proposed: design and evaluation of Metropolitan Area Network (MAN) architectures; performance evaluation and topology configuration of Broadband ISDNs; interconnection of LANs, MANs and B-ISDNs. Novel metropolitan network architectures based on tree topologies and wavelength division multiplexing will be investigated, with the goal of achieving much higher speeds (in the Gigabit range) than available from existing MAN products. Network control and management techniques for high speed, wide area networks will be developed to guarantee efficiency and to prevent congestion.
