High-speed Panamanian Telecommunications Network for Global Change Research

Coates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流量都通过哥斯达黎加，使用128个CUBS卫星连接到互联网。史密森热带研究所(Smithsonian Tropical Research Institute)和巴拿马学术网络(RAP)通过一条19.2只幼崽的座机通过哥斯达黎加与因特网相连。这种小带宽的固定线路不能满足巴拿马研究界的需求，而且出了名的不稳定。为了满足STRI研究人员的需求，Smithsonian Institution(SI)在STRI的Tivoli/Tper设施安装了卫星天线。STRI已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CUBS的流量，但如果需要，该链路可以扩展到全T1连接(24个)。在计划的安装完成后，以下实验室设施将与Tivoli/Tper卫星天线相连：1.在Tivoli/Tper内部，现有局域网上的100多个工作站将与卫星天线连接。2.STRI Naos海洋研究实验室现有的一个20站局域网，距离3.5公里，将增加一个服务器，并通过扩频无线链路与Tivoli/Tper相连。STRI将为NAOS实验室额外提供30台工作站，并将这些机器连接到局域网。3.在科罗拉多州巴罗市建立现有的局域网。科学与技术研究所的主要陆地研究地点(BCI)距离蒂沃利/塔佩尔30多公里，目前通过与巴拿马运河委员会的光缆的微波链路连接到蒂沃利/塔珀。SI计划为BCI内的局域网的重大扩展提供资金，STRI已请求国家科学基金会提供支持，以升级微波链路以支持这一扩展。4.将使用扩频无线链路将现有的广域网连接到蒂沃利/塔佩尔，以连接区域行动方案的成员(巴拿马理工大学、巴拿马大学、安提瓜圣玛大学)。5.国家可再生自然资源研究所(可再生自然资源研究所)的局域网目前没有连接到因特网，距离Tivoli/Tper 20公里将需要在两条专用英特尔电话线上使用两个大容量调制解调器。INRANARE与局域网的因特网连接还需要一个4Mb服务器、一个路由器、一个收发器和一个UPS。本提案中要求的增量设备将允许巴拿马史密森热带研究所(STRI)的全球变化研究社区充分参与对成功和尖端研究计划至关重要的数据和信息的电子交换。STRI拥有许多第一科学质量的数据集，任何其他方式都很难访问这些数据集。STRI在热带森林科学中心50公顷的全球系统中记录最好的地点运作，并拥有其珊瑚礁监测计划40多年的数据。除了科学与技术研究所之外，巴拿马学术研究网络(RAP)的所有成员--巴拿马理工大学(UTP)以及国家可再生自然资源研究所(INRENARE)--的其他几个研究机构也将受益于这项改进的服务。巴拿马是美洲全球变化研究所(IAI)的成员国，该研究所是美国的一项倡议，旨在鼓励美洲各科学机构就全球变化问题开展合作研究。国家科学基金会是白宫指定的美国政府机构，负责履行美国在IAI内的职责。

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.
