Abstract

Current and future network services and applications are expected to revolutionize our society and lifestyle. At the same time, the abundant possibilities that new network technologies offer to end users, network operators and administrators have created a cumbersome network configuration process to accommodate all different stakeholders and applications. Thus, lately, there is a need to simplify the management and configuration of the network, through possibly an autonomic and automatic way. Intent Based Networking (IBN) is such a paradigm that envisions flexible, agile, and simplified network configuration with minimal external intervention. This paper provides a detailed survey of how the IBN concept works and what are the main components to guarantee a fully autonomous IBN system (IBNS). Particular emphasis is given on the intent expression, intent translation, intent resolution, intent activation and intent assurance components, which form the closed loop automation system of an IBNS. The survey concludes with identifying open challenges and future directions of the problem at hand.

基于意图的网络研究综述

当前和未来的网络服务和应用有望彻底改变我们的社会和生活方式。与此同时，新网络技术为最终用户、网络运营商和管理员提供的大量可能性已经创建了一个繁琐的网络配置过程，以适应所有不同的利益相关者和应用程序。因此，最近有必要通过可能的自主和自动方式简化网络的管理和配置。基于意图的网络(IBN)就是这样一种范例，它设想了在最小的外部干预下灵活、敏捷和简化的网络配置。本文详细介绍了IBN概念的工作原理，以及保证完全自主IBN系统(IBNS)的主要组件。重点介绍了构成IBNS闭环自动化系统的意图表达、意图翻译、意图解析、意图激活和意图保证组件。调查最后确定了当前问题的公开挑战和未来方向。

期刊介绍： IEEE Communications Surveys & Tutorials is an online journal published by the IEEE Communications Society for tutorials and surveys covering all aspects of the communications field. Telecommunications technology is progressing at a rapid pace, and the IEEE Communications Society is committed to providing researchers and other professionals the information and tools to stay abreast. IEEE Communications Surveys and Tutorials focuses on integrating and adding understanding to the existing literature on communications, putting results in context. Whether searching for in-depth information about a familiar area or an introduction into a new area, IEEE Communications Surveys & Tutorials aims to be the premier source of peer-reviewed, comprehensive tutorials and surveys, and pointers to further sources. IEEE Communications Surveys & Tutorials publishes only articles exclusively written for IEEE Communications Surveys & Tutorials and go through a rigorous review process before their publication in the quarterly issues. A tutorial article in the IEEE Communications Surveys & Tutorials should be designed to help the reader to become familiar with and learn something specific about a chosen topic. In contrast, the term survey, as applied here, is defined to mean a survey of the literature. A survey article in IEEE Communications Surveys & Tutorials should provide a comprehensive review of developments in a selected area, covering its development from its inception to its current state and beyond, and illustrating its development through liberal citations from the literature. Both tutorials and surveys should be tutorial in nature and should be written in a style comprehensible to readers outside the specialty of the article.
