 大多数企业网络无法处理大数据负载
 ======
-As more data moves through the network, efforts to keep up are lagging due to leadership and technology issues.
+随着越来越多的数据通过网络传输，由于领导力和技术问题，数据网络跟上数据传输速度的工作正在滞后。

-Another week, another survey that finds IT cannot keep up with the ever-expanding data overload. This time the problem surrounds network bandwidth and overall performance.
+又过了一周，另一项调查发现，IT已经无法跟上不断膨胀的数据过载。这次问题将围绕着网络带宽和整体性能展开。
 
-[A survey of 300 IT professionals][1] conducted by management consultant firm Accenture found the majority feel their enterprise networks are not up to the task of handling big data and internet of things (IoT) deployments. Only 43% of those companies polled said their networks are ready to support the cloud, IoT, and other digital technologies.
+管理咨询公司埃森哲（Accenture）对[300名IT专业人士进行的一项调查][1] 发现，大多数人感觉他们企业网络无法胜任处理大数据的任务和物联网 (IoT) 部署。只有43%的受访公司表示他们的网络已经准备好支持云服务、物联网和其他数字技术。

-A key reason (58%) is a “misalignment between IT and business needs” that is slowing those rollouts. That is an unusual finding, since 85% of respondents also reported that their networks were completely or mostly ready to support the business’ digital initiatives. So which is it?
+一个关键原因（58%）是“IT与商业需求的不一致性”，这减缓了这些项目的推出。这是一个不同寻常的发现，因为85%的受访者也表示他们的网络已经完全或者大体上已经准备好支持企业的数字化计划。到底是哪一个呢？
 
-The second and third most commonly cited barriers were “inherent complexities between business requirements and operational needs” and “demands for bandwidth, performance, etc. outpacing the ability to deliver” at 45% each.
+第二和第三大时常提及的障碍是“业务需求和运营需求间固有的复杂性”以及“对带宽、性能等方面的需求超过交付能力”，各占45%。
 
-Network bottlenecks continue to grow as the sheer amount of data being pumped over the wires continues to increase thanks to analytics and other big data technologies. The survey found that bandwidth demands were not being met and current network performance continues to fall short.
+由于分析技术和其他大数据技术的推动，大量传输数据持续涌入网络线路，网络瓶颈持续增长。调查发现，带宽需求并未满足，目前的网络性能依旧达不到要求。
 
-Other reasons cited were lack of networking skills, device sprawl, and aging equipment.
+其他原因还包括缺乏网络技术、设备扩展和设备老化。
 
-### One solution to network performance woes: SDN
+### 网络性能问题的一个解决方案：SDN
 
-Accenture found that most firms said [software-defined networks (SDN)][5] were the solution for bandwidth and performance challenges, with 77% of those surveyed reporting they were in the process of deploying SDN or have completed the deployment. It qualified that, noting that while SDN may be in place in parts of the organization, it is not always rolled out uniformly enterprise-wide.
+埃森哲发现，大多数公司表示 [软件定义网络 (SDN)][5] 是应对带宽和性能挑战的解决方案，77%的受访企业在调查中表示正在部署SDN或者已完成部署。它指出，虽然SDN可能在组织的某部分中存在，它并不总是在整个企业范围内统一地推出。

-Now, while it seems no one ever has enough budget for all of their IT ambitions, 31% of those surveyed describe funding network improvements as “easy” and within the network infrastructure team’s control, with CIOs/CTOs being much more likely to report the funding process as “easy” (40%), compared to their direct reports (13%) or directors and vice presidents of infrastructure/network (19%). 
+如今看来，似乎从未有人有足够的预算来满足他们所有的IT雄心，但31%受访者认为网络改善筹资“简单”。而且在网络基础设施团队的控制下，首席信息官/首席技术官更可能将融资过程报告为“轻松”（40%），相较于直接下属（13%）或基础设施/网络主管和副总裁（19%）。 
 
-Saying, "Legacy networks alone cannot support the innovation and performance required in the digital age," the report calls for embracing new technologies, without saying SDN by name. It also called for greater collaboration between the C suite and their direct reports because it was clear there was a disconnect between how the two sides viewed things.
+报告指出，“仅靠传统网络无法支持数字时代所需的创新和性能。”呼吁拥抱新技术，但没有提到SDN的名字。同时呼吁首席执行官和他们直接下属间加强合作，因为很明显，双方在看待问题的方式上存在分歧。
 
-"We believe a new network paradigm is needed to ensure networks meet current and future business needs. However, although there are signs of progress, the pace of change is slow. Companies must undertake significant work before they achieve a unified and standardized enterprise capability that will offer the bandwidth, performance and security necessary to support business needs today—and tomorrow," the report concluded.
+报告总结说，“我们认为需要一种新的网络范式来确保网络满足当前和未来的业务需求。然而，尽管有进步的迹象，但改变的步伐缓慢。公司必须承担起重担，才能实现统一和标准化企业能力，提供必要的带宽、性能和安全，以支持当前和未来的业务需求”。
