鉴于有TX对美国网络存在偏见，特找来一篇博文与大家分享。有错误的地方还请专业人士指正。 地广人稀，这点美国跟澳洲相似。以美国的国力和经济发达程度，美国政府尚未有雄心勃勃的 全国光纤网络计划来造福民众和产业；以古狗的技术水平，尚且需要先在小范围技术试点。以 澳洲有限的技术水平、不算多的GDP外加沉重的福利负担，一张口就是覆盖93%国土面积、光 纤到户，是否有点脱离实际了呢？-- 译者 古狗博克 由产品经理米妮.英格索  和简姆斯.凯利发布 千兆的大胆设想：我们的光纤实验网络 2010年2月10日上午08时00分 想象一下，在乡下卫生所，用网络把三维医学成像传送到纽约，跟在纽约的专家讨论病人的病情。或者在不到5分钟的时间里下载一部高清晰度的电影。或在与世界各地的同学们一边协作，一边看大学的3D教学视频直播。通用，超高速互联网接入将使这一切变为可能。我们已经敦促联邦通讯委员会研究新的、创造性的国家宽带计划方案来实现这一目标 - 今天，我们宣布我们自己的实验。 我们正在在美国少数几个地方规划建设和测试超高速宽带网络。我们将提供比大多数美国人正在使用的互联网速度快100倍以上的千兆网络接入 - 光纤到户连接。我们计划在初期为5万人提供有价格竞争力的服务，并争取提高至50万人。 我们的目标是要尝试新的方法使每个人可以得到更好，更快的互联网。下面是一些我们考虑到的具体情况： *下一代应用程序：我们想看看开发者和用户在超高速环境下有什么可以做的，无论是开创新的高带宽“杀手应用程序”和服务，或我们还不能想象的其他用途。 *新的布线技术：我们会尝试用新的方法来建立光纤网络，并为在其他地方布署光纤(的人们)提供信息和支持，我们将与世界分享我们吸取的教训。 *开放和选择：我们将运作一个“开放式接入”网，使用户有多个网络服务供应商可供选择。与我们过去的一贯主张一致的是，我们将以开放的、非歧视性和透明的方式管理我们的网络。 正像我们在山景的WiFi无线网一样，这个项目的目的是实践和学习。网络提供商在扩大和改善高速因特网接入上正在取得实质性的进展，但仍有更多工作要做。我们认为仍有许多问题需要解决 - 但通过我们的试验，我们希望能在为大家提供更快、更好的互联网这个共同目标作出有意义的贡献。 Google Blog Posted by Minnie Ingersoll and James Kelly, Product Managers Think big with a gig: Our experimental fiber network 2/10/2010 08:00:00 AM Imagine sitting in a rural health clinic, streaming three-dimensional medical imaging over the web and discussing a unique condition with a specialist in New York. Or downloading a high-definition, full-length feature film in less than five minutes. Or collaborating with classmates around the world while watching live 3-D video of a university lecture. Universal, ultra high-speed Internet access will make all this and more possible. We've urged the FCC to look at new and creative ways to get there in its National Broadband Plan – and today we're announcing an experiment of our own. We're planning to build and test ultra high-speed broadband networks in a small number of trial locations across the United States. We'll deliver Internet speeds more than 100 times faster than what most Americans have access to today with 1 gigabit per second, fiber-to-the-home connections. We plan to offer service at a competitive price to at least 50,000 and potentially up to 500,000 people. Our goal is to experiment with new ways to help make Internet access better and faster for everyone. Here are some specific things that we have in mind: * Next generation apps: We want to see what developers and users can do with ultra high-speeds, whether it's creating new bandwidth-intensive "killer apps" and services, or other uses we can't yet imagine. * New deployment techniques: We'll test new ways to build fiber networks, and to help inform and support deployments elsewhere, we'll share key lessons learned with the world. * Openness and choice: We'll operate an "open access" network, giving users the choice of multiple service providers. And consistent with our past advocacy, we'll manage our network in an open, non-discriminatory and transparent way. Like our WiFi network in Mountain View, the purpose of this project is to experiment and learn. Network providers are making real progress to expand and improve high-speed Internet access, but there's still more to be done. We don't think we have all the answers – but through our trial, we hope to make a meaningful contribution to the shared goal of delivering faster and better Internet for everyone.
