In this talk, we examine change and the rate of change from antiquity to the present, and we extrapolate to the future. We draw on the measures of social development due to historian Ian Morris. This shows that we are in an age of exponentially-increasing rate of change that will only increase unpredictably in the future. This necessitates a flexible architecture for the Internet to handle the future. We motivate the needs by the FarmerZone project, a futuristic application of AI to precision agriculture in India. Software-defined networks (SDN) is a promising alternative to the inflexible hardware routers of today's Internet. We discuss some of the challenges of SDN. One is rollout of SDN routers without disrupting the Internet. Another is scalability of the control plane of SDN. As SDN tends to be multi-vendor, ensuring security is a particularly difficult challenge. Rapid mobility with wireless networks is another issue.

沉思于变化：SDN驱动程序

在本次演讲中，我们研究了从古代到现在的变化和变化率，并推断了未来。我们借鉴了历史学家伊恩·莫里斯（Ian Morris）提出的社会发展措施。这表明，我们正处于一个变化率呈指数级增长的时代，将来这种变化只会以不可预测的速度增长。这就需要互联网具有灵活的体系结构来应对未来。我们通过FarmerZone项目激发了需求，该项目是AI在印度精密农业中的未来应用。软件定义网络（SDN）是当今Internet灵活的硬件路由器的有前途的替代方案。我们讨论了SDN的一些挑战。一种是在不中断Internet的情况下推出SDN路由器。另一个是SDN控制平面的可伸缩性。由于SDN往往是多供应商，确保安全是特别困难的挑战。无线网络的快速移动性是另一个问题。
