NeTS: Medium: KnowOps-Making Network Management and Operations Software Defined

网络运营的复杂性和由此产生的运营成本(OPEX)是网络运营商面临的最大挑战之一。这种复杂性的产生部分是因为现代网络的规模和持续增长，这些网络运行的协议的固有复杂性和错综复杂的依赖关系，以及由于网络连接和联网服务在社会中发挥越来越重要的作用而提高了网络用户的期望。最近的发展使网络变得更加动态，使网络管理和运营(M&amp；O)的复杂性增加了一个全新的维度，从而加剧了这种复杂性。由此产生的事态阻碍了网络创新和变革的步伐。网络管理与运营的研究没有跟上网络自身变革的步伐，本项目通过设计和构建一个以知识为中心的软件定义的网络管理和运营体系结构(KnowOps)来解决这些问题。KnowOps将代表着M&Amo朝着完全自主运营迈出的重要一步。该项目将概括类似数据库的抽象，以创建网络运营结构(NOF)，作为全面网络管理和运营的系统和原则性基础。PIS将把这一基础与以信息为中心的数据挖掘方法结合起来，创建一个结构化的信息库，以系统的方式捕获网络的状态，并将其暴露给其他网络管理功能。最终结果将是一个知识库，能够系统地捕获领域专家指定的操作程序和策略。网络运营支出是数字技术继续渗透到家庭和小型企业应用领域的主要挑战。该项目将涉及与一家大型全国性网络运营商的合作，但也将与一家以农村为主的小型运营商合作。改进的网络管理工具对于服务于网络弱势社区的较小区域运营商尤其重要，这些运营商往往没有较大运营商的技术广度和深度，但他们面临着同样的运营挑战。

The operational complexity of networks and the resulting operational expense (OPEX) count among the top challenges faced by network operators. This complexity arises, in part, because of the scale and continued growth of modern networks, the inherent complexity and intricate dependencies of the protocols that these networks run, and the increased expectations of network users due to the increasing importance that network connectivity and networked services play in society. This complexity has been heightened by recent developments that make networks much more dynamic, adding a whole new dimension to the complexities of network management and operations (M&O). The resulting state of affairs acts to impede the pace of innovation and change in networks. The research on network M&O has not kept pace with the research transforming the networks themselves.This project addresses these issues by designing and building a Knowledge-Centric Software-Defined Network Management and Operations architecture (KnowOps). KnowOps will represent a significant step in moving M&O towards fully autonomic operation. The project will generalize database-like abstractions to create a network operations fabric (NOF) as a systematic and principled foundation for comprehensive network management and operations. The PIs will combine this foundation with information centric data mining methods to create a structured information base which captures, in a systematic manner, the status of the network and expose it to other network management functions. The end result will be a knowledge base capable of systematically capturing operational procedures and policies as specified by domain experts. Network OPEX is a major challenge for continued penetration of digital technologies into application areas in the home and small business. The project will involve collaboration with a large, national network operator but also with a small, mostly rural carrier. Improved network management tools are particularly important for smaller regional operators serving cyber-disadvantaged communities, who often do not have the technical breadth and depth of larger operators, but who, nonetheless, face the same operational challenges.
