论文摘要
整个互联网一直保持在服务提供商和自主系统的控制之下。物联网（IoT）和边缘计算提供了不断增长的需求，并为其Web服务工作流提供了更多用户控制。网络软件化将在构建，逐步部署和维护环境的各个阶段彻底改变网络格局。软件定义的网络（SDN）和网络函数虚拟化（NFV）是网络软件化的两个核心原则。 SDN通过抽象数据平面中网络设备的控制来提供逻辑集中的控制平面。 NFV虚拟化专用的硬件中间箱，并将其部署在服务器和数据中心之上，作为网络函数。因此，网络软件化可以通过增强其控制并改善网络服务的可重复性来有效地管理系统。在这项工作中，我们提出了针对潜伏敏感的Web服务工作流的软件定义的Internet（SDI）的愿景。 SDI将网络软焊接扩展到Internet规模，以在Internet上启用延迟感知的用户工作流执行。
The Internet, at large, remains under the control of service providers and autonomous systems. The Internet of Things (IoT) and edge computing provide an increasing demand and potential for more user control for their web service workflows. Network Softwarization revolutionizes the network landscape in various stages, from building, incrementally deploying, and maintaining the environment. Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are two core tenets of network softwarization. SDN offers a logically centralized control plane by abstracting away the control of the network devices in the data plane. NFV virtualizes dedicated hardware middleboxes and deploys them on top of servers and data centers as network functions. Thus, network softwarization enables efficient management of the system by enhancing its control and improving the reusability of the network services. In this work, we propose our vision for a Software-Defined Internet (SDI) for latency-sensitive web service workflows. SDI extends network softwarization to the Internet-scale, to enable a latency-aware user workflow execution on the Internet.
