Winsborough With National Science Foundation support, the University of Wisconsin's Social Sciences Computing Co-operative will purchase a Fiber Distributed Data Interface backbone for its extensive computing network. This high-bandwidth backbone is necessary to the very data-intensive research done in the Co-op. work which uses a 50 gigabyte, on-line, data base of government and privately collected data files from the U.S. and around the world. The current network is an amalgam of older and more modern equipment using a 10 mb/s ethernet specification. Some of the older technology is slow and some is fragile and this seriously impedes research. The backbone is overloaded in the older part of its topology and peak daily loads are several times industry recommendations. It has become fragile and causes frequent interruptions for researchers along its path. The network to be constructed will have from 30 to 60 times the current bandwidth. It will both serve current users and add Department of Economics researchers to the system. The Social Sciences Computing Co-operative is composed of five research and teaching agencies in the University of Wisconsin and includes the Center for Demography and Ecology, the Department of Sociology, the Department of Rural Sociology, the Institute on Aging and Adult Life and the Institute for Research on Poverty. About 100 faculty and their teams of graduate assistants and professional researchers use the co-op facilities. The research conducted focuses on human resources, demography and the causes and consequences of global change, especially as it relates to the physical environment. The work contributes in a significant way to the increase in basic scientific knowledge much of it relevant to pressing national needs.

温斯伯勒 在国家科学基金会的支持下，威斯康星州大学的社会科学计算合作组织将为其广泛的计算网络购买光纤分布式数据接口主干。这个高带宽的主干网是必要的非常数据密集型的研究所做的合作。工作使用50千兆字节，在线，数据库的政府和私人收集的数据文件从美国和世界各地。目前的网络是使用10 mb/s以太网规范的旧设备和更现代设备的混合体。有些旧技术进展缓慢，有些则很脆弱，这严重阻碍了研究。主干网在其拓扑结构的旧部分过载，峰值日负载是行业建议的几倍。它已经变得很脆弱，沿着的研究人员经常受到干扰，将要建造的网络将拥有目前带宽的30至60倍。 它既为当前用户服务，又将经济系研究人员加入系统。 社会科学计算合作社由威斯康星州大学的五个研究和教学机构组成，包括人口与生态中心、社会学系、农村社会学系、老龄化和成人生活研究所以及贫困研究所。 大约100名教师和他们的研究生助理和专业研究人员团队使用合作社设施。所进行的研究侧重于人力资源、人口以及全球变化的原因和后果，特别是因为它与自然环境有关。这项工作极大地促进了基础科学知识的增加，其中大部分与国家的迫切需要有关。
