DESCRIPTION (provided by applicant): The aims of this supplement are to provide fast, reliable intranet and Internet services to link the science faculty and students across campus, and to provide faculty and students with essential training and support in use of these services. A fault-tolerant, scaleable, load balanced, and configurable system has been designed to provide the necessary infrastructure. These characteristics will be assured through multiple DSL lines, and a wide-area network (WAN) for the science community via a gigabit-over-copper backbone (to be furnished by the university) plus wireless (802.11 b) connections to more remote buildings on campus. A two-level help desk system will be implemented to train and support students and faculty, while at the same time providing work experience for computer science students. In addition to providing all science faculty and students with basic Internet and file sharing capabilities, the system will enable use of live Internet in class, computer-mediated instruction and testing, and access to campus resources such as the RISE servers and the library (e.g., online journals). Internet capabilities at U. Guam are limited by bandwidth (11/2 Tl lines total, or ~2250K bps) and unreliable connections through the Computer Center proxy servers. The network connecting the various college LAN's to allow them to access the leased-line Internet connection from the Computer Center is a mixture of fiber loops and point-to-point connections between the computer center and some colleges. The capacity of the current infrastructure is insufficient to provide the bandwidth-intensive services being developed including those in the RISE program IT classroom. Security concerns with the present mixed administrative/academic computing prevent file sharing between buildings. The present system is very prone to failure, and email and Internet services are frequently unavailable; most students and faculty do not have effective access to the Internet from campus; this is a serious impediment to the training goals of the RISE program and the research (including SCORE) projects at UOG. Project objectives, specified in measurable terms and evaluation questions, will be tracked through to allow evidence-based decision-making on the future development of the campus network. The infrastructure and the support service will serve as a model for further development of a proposed campus-wide Academic Computing Services, and the network can be reconfigured to integrate fully with the university system beyond the end of the grant period. The system is a novel solution to our unusual circumstances, and has been reviewed by Cisco-trained engineers.

描述（由申请人提供）：本补充文件的目的是提供快速、可靠的内联网和互联网服务，以连接整个校园的科学教师和学生，并为教师和学生提供使用这些服务的基本培训和支持。 容错、可扩展、负载平衡且可配置的系统旨在提供必要的基础设施。这些特性将通过多条 DSL 线路和科学界的广域网 (WAN) 来保证，该广域网通过千兆铜缆主干网（由大学提供）以及与更偏远建筑物的无线 (802.11 b) 连接在校园里。将实施两级服务台系统来培训和支持学生和教师，同时为计算机科学专业的学生提供工作经验。除了为所有理科教师和学生提供基本的互联网和文件共享功能外，该系统还将支持在课堂上使用实时互联网、以计算机为媒介的教学和测试，以及访问 RISE 服务器和图书馆（例如图书馆）等校园资源。 ，在线期刊）。 U.Guam 的互联网功能受到带宽（总共 11/2 Tl 线路，或约 2250K bps）和通过计算机中心代理服务器的不可靠连接的限制。连接各个学院 LAN 以允许它们从计算机中心访问租用线路互联网连接的网络是计算机中心和一些学院之间的光纤环路和点对点连接的混合体。当前基础设施的容量不足以提供正在开发的带宽密集型服务，包括 RISE 计划 IT 教室中的服务。当前混合管理/学术计算的安全问题阻碍了建筑物之间的文件共享。现有系统很容易出现故障，电子邮件和互联网服务经常无法使用；大多数学生和教师无法从校园有效访问互联网；这严重阻碍了 UOG 的 RISE 计划和研究（包括 SCORE）项目的培训目标。 将跟踪以可衡量的术语和评估问题指定的项目目标，以便对校园网络的未来发展做出基于证据的决策。基础设施和支持服务将作为进一步开发提议的校园范围学术计算服务的模型，并且可以重新配置网络，以便在资助期结束后与大学系统完全集成。该系统是针对我们异常情况的新颖解决方案，并且已经过思科培训工程师的审查。
