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。

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？

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%。

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。

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。

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%）。

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。

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”。
