应用程序和网络控制平面之间的强烈划分是可取的，但使网络对应用程序的最终目的一无所知，因此无法优化这些应用程序。另一种方法是应用程序向网络声明其抽象需求;例如，“我需要组多播”或“我将在本地域内运行并且对延迟敏感”。这种丰富的语义具有使网络能够更好地实现应用意图的潜力，同时还有助于优化跨应用的网络资源使用。我们将这种方法称为意图驱动网络（IDN）。我们勾画了一个渐进式部署的设计，作为一个垫脚石，在今天的互联网上实现IDN。
The strong divide between applications and the network control plane is desirable, but keeps the network in the dark regarding the ultimate purpose of applications and, as a result, is unable to optimize for these. An alternative approach is for applications to declare to the network their abstract desires; e.g. “I require group multicast”, or “I will run within a local domain and am latency sensitive”. Such an enriched semantic has the potential to enable the network to better fulfill application intent, while also helping optimize network resource usage across applications. We refer to this approach as intent driven networking (IDN). We sketch an incrementally-deployable design to serve as a stepping stone towards a practical realization of IDN within today's Internet.
