High-speed Panamanian Telecommunications Network for Global Change Research

科茨 目前，来自巴拿马、萨尔瓦多、尼加拉瓜、洪都拉斯和危地马拉的所有区域电子通信都是通过哥斯达黎加，利用128 cubs卫星连接到因特网。 史密森热带研究所和巴拿马学术网通过哥斯达黎加的一条19.2小熊的陆地线路与因特网联接。 这种小带宽的陆地线路不足以满足巴拿马研究界的需求，而且众所周知不稳定。 为了满足STRI研究人员的需求，史密森学会（SI）在STRI的Tivoli/Tupper设施安装了一个卫星天线。 STRI将其新安装的卫星链路的一半带宽提供给RAP。 这条卫星链路最初将用于处理128个幼仔的通信量，但如果需要，该链路可扩大到一个完整的T1连接（24 x 64个幼仔）。 在计划的安装完成后，以下实验室设施将连接到Tivoli/Tupper卫星天线：1。 在Tivoli/Tupper内部，现有局域网（LAN）上的100多个工作站将连接到卫星天线链路。 2. 3.5公里外的STRI Naos海洋研究实验室现有的20个站点局域网将增加一个服务器，并通过扩展频谱无线链路与Tivoli/Tupper连接。 STRI将为Naos实验室提供另外30个工作站，并将这些机器与局域网连接。 3. 巴罗科罗拉多的现有LAN。岛屿（BCI）是STRI的主要陆地研究地点，距离超过30公里，目前通过微波链路与巴拿马运河委员会的光纤电缆连接到Tivoli/Tupper。 SI计划为BCI内部LAN的重大扩展提供资金，STRI已请求NSF支持微波链路的升级，以支持这一扩展。 4. 连接RAP成员（巴拿马科技大学（UTP）、巴拿马大学（UP）、安提瓜圣马尔大学（USMA））的现有广域网将使用扩频无线链路连接到Tivoli/Tupper。 5. 国家可再生自然资源研究所的局域网目前没有与因特网连接，而距离Tivoli/Tupper 20公里的地方将需要通过两条专用的INTEL电话线使用两个大容量调制解调器。 与INRANARE局域网的互联网连接还需要一个4 Mb服务器、一个路由器、一个收发器和一个UPS 本提案所要求的增量设备将使巴拿马史密森热带研究所的全球变化研究界能够充分参与电子数据和信息交换，这对成功的尖端研究方案至关重要。 STRI拥有许多第一科学质量的数据集，这些数据集很难通过任何其他方式获得。 STRI在热带森林科学中心全球50公顷地块系统中记录最好的地点开展工作，并拥有超过40年的珊瑚礁监测计划数据。 除了STRI之外，其他几个研究机构也将受益于这一改进的服务，所有巴拿马学术研究网络（RAP）的成员：巴拿马科技大学（UTP）以及国家可再生自然资源研究所（INRENARE）。 巴拿马是美洲全球变化研究所的成员国，该研究所是美国的一项倡议，旨在促进美洲科学机构就全球变化问题开展合作研究。 国家科学基金会是美国政府机构，由白宫指定，在IAI内履行美国的职责。

Coates Currently, all regional electronic traffic from Panama, El Salvador, Nicaragua, Honduras and Guatemala is channeled through Costa Rica, using a 128 cubs satellite link to the Internet. The Smithsonian Tropical Research Institute (STRI) and the Panamanian Academic Network (RAP) are linked to the Internet through Costa Rica via a 19.2 cubs land line. This small-bandwidth land line is inadequate for the needs of the research community of Panama, and is notoriously unstable. In order to address the needs of the researchers at STRI, the Smithsonian Institution (SI) has installed a satellite dish at STRI's Tivoli/Tupper facility. STRI has offered half of the bandwidth of its newly installed satellite link to RAP. This satellite link will be initially installed to handle traffic of 128 cubs, but the link can be expanded up to a full T1 connection (24 x 64) cubs) should the need arise. Following laboratory facilities will be connected to the Tivoli/Tupper satellite dish after the planned installation is completed: 1. Within Tivoli/Tupper itself, over 100 workstations on an existing Local Area Network (LAN) will be connected to the satellite dish link. 2. An existing 20 station LAN at the STRI Naos marine research laboratory, 3.5 km distant, will be augmented by a server and connected via a spread-spectrum wireless link to Tivoli/Tupper. STRI will supply an additional 30 workstations for the Naos Laboratory, and connect these machines to the LAN. 3. An existing LAN at Barro Colorado. Island (BCI), STRI's principal terrestrial research site, over 30 km distant, is currently connected to Tivoli/Tupper by a microwave link to the Panama Canal Commission's fiber optic cable. SI plans to fund a major expansion of the LAN within BCI, and STRI has requested support from NSF for the upgrading of the microwave link to support this expansion. 4. An existing Wide Area Network linking the members of the RAP (the Technological University of Panama (UTP), the University of Panama (UP), th e University of Santa Mar a Antigua (USMA)) will be connected using a spread spectrum wireless link to Tivoli/Tupper. 5. The LAN at the National Institute for Renewable Natural Resources (INRENARE) currently has no link to the Internet, and the 20 km distance to Tivoli/Tupper will require the use of two high-capacity modems over two dedicated INTEL telephone lines. The Internet link to the LAN at INRANARE will also require a 4 Mb server, a router, a transceiver, and a UPS The incremental equipment requested in this proposal will allow the global change research community at the Smithsonian Tropical Research Institute (STRI) in Panama to participate fully in the electronic exchange of data and information crucial to a successful and cutting-edge research program. STRI has many data sets of the first scientific quality that would be difficult to access any other way. STRI operates on of the best documented sites within the Center for Tropical Forest Science's global system of 50-hectare plots, and has over forty years of data from its coral reef monitoring program. In addition to STRI, several other research institutions will benefit from this improved service, all members of the Panamanian Academic Research Network (RAP): the Technological University of Panama (UTP), as well as the National Institute for Renewable Natural Resources (INRENARE). Panama is a Member State of the inter-American Institute for Global Change Research (IAI), a U.S. initiative to stimulate cooperative research on global change issues among the scientific institutions of the Americas. The National Science Foundation is the U.S.Government agency designated by the White House to carry out U.S. responsibilities within the IAI.
