Theory on economic growth-the importance of broadband-IT broadband upgrade information On the importance of broadband upgrade to economic growth

Overview: consumers, businesses, research institutes and education on Internet usage has been growing exponentially, this pattern of growth is also great pressure on our current broadband infrastructure. Now, people seem to fail to take into account the broadband networks of importance to economic growth and prosperity.

To this end, the United States further communication (CIENA), Senior Vice President and Chief Technology Officer of shidifu·yalishanda (Steve Alexander) recently, " why broadband network upgrades are essential to economic growth ," explains this issue. Alexander's article reads.

Argument "improving United States federal debt ceiling if the correct options for the country" as this topic, networking industry is now embroiled in a debate about this debate is around the "need to improve network data connection speeds" expand this theme. Network capacity-constrained circumstances, such restrictions on consumers, businesses, research institutions and the economy as a whole are very unfavourable, and network-related developments and innovations will be limited restrictions, in such situations, television role as an important economic driver is supposed to need to upgrade to greater levels of concern.

High-speed, high-capacity network to our decision will play an important role in the future, because this will support the global Internet and digital economy. To a large extent, based on 100G technology network has become the solution to the current mainstream development needs, and this is also reflected in the traditional network architecture and the size of a great leap forward. It should be said that soon after, our network technology base will exceed 100G, will even expand to 400G, 10Terabit is more likely to create the network.

Wire fees:

There is no doubt that more and more users demand for networking. We have "fast-track" to be a "connected world", in fact, it is just beginning. According to Internet World Stats data shows that over the past 10 years, the global number of Internet users grew by as much as 7 times, increasing from per cent in 2000 to 2.4 billion in 2012. In order to ensure that 2.4 billion people enjoy a high quality experience of the Internet, so some people think, network communications infrastructure should also be expanded to 7 times more than doubled, so now users can have, like 12 years ago, the network speed.

However, as we all know, that is not the case.

Today, the enormous changes in the way we use the Internet. Facebook unveiled in early 2004, and YouTube launched in 2005 launched; Netflix started streaming video services in 2007, Hulu.com and in 2008 after joining the ranks of video streaming service. These services have been clearly reflects how consumers use the Internet has evolved from a simple text email into rich media and streaming video services. In addition, except for wired connection to network, wireless Internet, also developed significantly. From this, then the simple connection of the pressure on traditional networks have been great.

According to our assessment, if New York City's 8 million people, only 10% population trying to stream movies, then the network infrastructure needs will be the network transmission capacity of 1.6Terabit per second. This demand will lead to overload your network, and by virtue of existing technologies to meet such needs also take enormous costs. However, if you are unable to provide the required speed, that would mean that users watch online video, there is a lower-quality picture playback, pixel count, pause and so on, which are not willing to accept the results of the current user.

This demand is the same, of course, also appears in the wireless Internet. Over the past 10 years, mobile devices (smartphones, tablet computers, e-readers, laptops etc) usage patterns can be described as showing explosive development. In fact, according to multiple news sources in the industry shows that global annual mobile device shipments this year are expected to reach more than 2 billion units. According to CCS Insight's data show that at the current pace, is expected by 2017, the mobile device shipments will exceed the number of the global population. As the number of these devices continues to grow, more and more rich media content is required by the user, in this case, we face the dilemma in network capacity.

A typical case:

Recently, the Denver Broncos football team (Denver Broncos), Vice President, IT business noted that in terms of this year's event, user has been uploading network traffic for the first time often exceeds the download traffic situation. The reason is this: user's "self portrait" and large play short video content results. In recognition of this situation, a football team-the San Francisco gold rush team (San Francisco 49ers) will be installed in their new Stadium next year a 10 Gbps Internet connection infrastructure to meet the needs of users.

Simply put, now it even higher speeds and more network capacity, to ensure that users have access to high quality experience.

Business user needs:

Business user does not make any difference. Because of measures IT virtualization and enterprise use of cloud computing, mobile, video, and bring your own device of Office policies and other factors affect enterprise user demand for network capacity is also on the rise. For enterprise users, data centers, corporate data center and between data centers to the cloud often also require more bandwidth, thus contributing to the day-to-day running, and do a data backup and recovery failures.

For example, medical institutions are faced with managing paper records to electronic medical data arising from the data file into the challenges of explosive growth. Today, more and more towards networked electronic medical records at the same time, picture archiving and communication systems (PACS) produced by image has a high resolution, which often require more network capacity, in addition, large files can reduce the traditional network speed. This change but also to the increase in the volume of data and storage, fault activity has brought an increasing number of problems, and these problems are medical IT industry has not previously been seen.

In fact, the United States Mongolia Institute of market research firm (Ponemon Institute) in 2012, the survey found that about 30% data storage of medical data. About 45% per cent of the respondents believed that their factory is planning to upgrade the storage devices in the coming year. There is no doubt that, with increasing storage requirements, bandwidth requirements are also on the rise.

Research and education network requirements:

Research and educational institutions around the world are engaged in projects require large amounts of bandwidth. From shaping the human brain (approximately 100 billion neurons, and spread over 1000 per cent between the connection point) model for this task, in General, this is equivalent to total 100 trillion connections points. In order to mimic the task, which requires a lot of high performance computing infrastructure and database technologies, and it also gives the network a lot of ability to pay.

For example, in 2010, Canada Brain Imaging Network (CBRAIN) shows how the network of 100-Gigabit per second links used to support research and development work. After using this connection speed, researchers in Canada brain imaging research network and the network of StarLight networks between d and 4D of Chicago video. This show also reflects the remote physicians and students how to use the Internet to learn new methods, look at patients as well as interacting with the surgical site.

Role of the network:

In the current circumstances, communications networks play an important role, and thus the demand for speed is imminent. Consumers, businesses, research institutes and education sectors to network communications infrastructure demand is also growing at an unprecedented rate. Investments that meet the needs of these advanced networks, to maintain user's love of new and better services also plays a crucial role, and this will ultimately promote revenue growth, and ultimately inspire research innovations.

论宽带升级对经济增长的重要性 - 宽带 - IT资讯
论宽带升级对经济增长的重要性

概述：消费者、企业、研究机构以及教育行业对互联网的使用量一直呈几何级数增长，这种迅猛增长的格局也对我们当前宽带基础设施形成了巨大压力。如今来看，人们似乎忽视了宽带网络的繁荣对经济增长的重要性。

为此，美国讯远通信(CIENA)公司高级副总裁兼首席技术官史蒂夫·亚历山大（Steve Alexander）近日对“宽带网络升级为何对经济增长至关重要”这一问题进行了阐述。亚历山大的文章内容如下。

如同争论“提高美国联邦债务上限是否为该国正确选择方案”这一话题一样，网络行业如今也卷入了一场争论，这种争论就是围绕“是否需要提高网络数据连接速度”这一主题而展开的。在网络能力受限的情况之下，这种限制对消费者、企业、研究机构以及整个经济都非常不利，而且网络相关的进展和创新必将受限制约，在这样的形势之下，宽带作为经济推动力的重要作用理应需要提升到更加令人关注的水平。

高速高能力的网络对我们的未来都将起着重要的决定作用，因为这样的网络将支撑着全球互联网和数字经济。在很大程度上，基于100G技术的网络已经成为解决当前发展需求的主流，而且这也体现了传统网络架构和规模的巨大飞跃。应当说，不久之后，我们的网络技术基础将突破100G，甚至会拓展到400G，更有可能会打造10Terabit的网络。

连网的费者：

毫无疑问，用户对网络的需求将会越来越多。我们已经“快速”成为一个“连网的世界”，事实上，这才是刚刚开始。据Internet World Stats的数据显示，在过去的10年中，全球互联网用户数量增长了7倍之多，从2000年的3.6亿增加到了2012年的24亿。为了确保这24亿网民能够享用高质量体验的互联网，因此也有人认为，网络通讯基础架构也应当扩容7倍多，这样现今的用户才能拥有与12年前一样的网络速度。

不过，众所周知，事实情况并非如此。

如今，我们使用互联网的方式也发生了巨大变化。Facebook于2004年初步亮相；YouTube于2005年开始上线；Netflix于2007年开始流视频服务，之后Hulu.com也于2008年加入了视频流服务的行列。这些服务已经明确体现出，消费者使用互联网的方式已经从简单的文本电子邮件转变成丰富的媒体和视频流等服务。另外，除了现在的有线连接网络之外，无线互联网也大大发展。由此可见，那么简单化连接的传统网络面临的压力已经很大。

据我们评估，如果纽约城800万人口中，只有10%的人口想同时使用流电影，那么网络基础设施的需求将是每秒钟网络传输容量达到1.6Terabit。这种需求将导致如今的网络负载过重，而且凭借现有的技术来满足这样的需求也将要耗费巨大成本。但是，如果无法提供所需的网速，那将意味着用户在观看网络视频时出现更低质量的回放、像素不清、画面停顿等现象，而这恰恰是当前用户所不愿意接受的结果。

这种同样的需求当然也出现在无线互联网之中。在过去的10年中，移动设备（智能手机、平板电脑、电子阅读器、笔记本等）使用量可以说是呈现出爆炸式的发展格局。事实上，据业界多个消息源显示，今年全球年度移动设备总出货量预计将达到20亿台以上。另据CCS Insight的数据显示，如果按照当前的速度发展，预计到2017年时，移动设备出货量将超过全球总人口数。随着这些设备数量的不断增长，丰富的网络媒体内容也越来越被用户所需，在这样的情况下，我们在网络能力方面又面临着两难困境。

典型案例：

最近，丹佛野马橄榄球队（Denver Broncos）的IT业务副总裁指出，在今年的赛事方面，首次出现了用户的网络上传流量常常超过下载流量的局面。其中的原因就是：用户的“自拍内容”和大戏剧短视频内容导致的结果。在认识到这一情况之后，另一支橄榄球队—旧金山淘金者队（San Francisco 49ers）将于明年在他们的新体育场内安装一对10 Gbps的互联网连接基础设施，以此来满足用户的需求。

简单地说，现在的确更高的网速和更强的网络能力，从而确保用户能够获得所需的高质量体验。

企业用户的需求：

企业用户并无什么不同。由于IT虚拟化措施和企业使用云计算、移动、视频以及携带自己设备办公之政策等多种因素的影响，企业用户对网络能力的需求量也在与日俱增。对企业用户而言，数据中心、公司数据中心之间以及数据中心到云之间往往也需要更多的带宽，从而促进日常运行，并做好数据备份工作和恢复故障等。

例如，医疗机构正面临着管理从纸质记录向电子数据文件转变而引发的医疗数据爆炸式增长所带来的挑战。如今，电子医疗记录越来越多的走向网络化，与此同时，图像存档与通信系统（PACS）制作的图像有着极高的分辨率，这往往需要更强的网络能力，另外，制作大文件也会降低传统的网络速度。这种变化也给数据和存储量增加、应对故障的难道活动等带来了越来越多的问题，而且这些问题也是医疗IT行业此前未曾出现过的。

事实上，美国市场研究机构波耐蒙研究所(Ponemon Institute)在2012年的一项调查发现，全球约30%的数据存储都是医疗数据。约45%的受访者认为，他们的工厂正计划在未来一年内对存储设备进行升级。毫无疑问，随着存储需求量的增加，带宽需求同样也在增加。

研究机构和教育行业的网络需求：

全球研究和教育机构都在从事需要大量带宽的项目。从塑造人脑（大约拥有1000亿个神经元，而且分布于1000至10000万个连接点之间）模型这一任务来看，总体而言，这就相当于是连接点总量达到100万亿个。为了完成这一模仿任务，这就需要大量高性能的计算化基础设施和数据库技术，而且这也给网络增加了大量的能力负担。

例如，2010年，加拿大大脑图像网络（CBRAIN）展示了每秒钟100吉比特的网络链接是如何用来支持研发工作的。使用了这种连接速度之后，研究人员能够在加拿大大脑图像网络的研究网络和芝加哥StarLight网络之间传输3D和4D视频图像。这种展示也体现了远程医生和学生如何使用网络来学习新医疗方法、观察病情以及与手术现场进行互动等。

网络的作用：

在当前的情况之下，通讯网络起着重要作用，因而对网速的需求也迫在眉睫。消费者、企业用户、研究机构和教育行业对通讯基础架构中的网络需求也在以前所未有的速度而增长。投资那些能够满足这些需求的先进网络，对维护用户对更新更好服务的爱好也起着非常关键的作用，而且这也将最终促进企业营收增长，并最终激发研究领域的创新。
