Abstract:
Software-Defined Wide Area Networks (SD-WAN) have revolutionized the traditional approach to WAN by offering greater flexibility, cost-efficiency, and performance optimization. However, as network demands evolve, there is a growing need to take SD-WAN a step further. This review explores the conceptual evolution of SD-WAN from traditional WAN architectures to autonomous, self-healing network systems. The next phase of SD-WAN involves the integration of advanced automation, artificial intelligence (AI), and machine learning (ML) to enable networks that can dynamically adapt, self-manage, and resolve issues in real-time, thereby significantly reducing human intervention. Traditional SD-WAN primarily focuses on centralized management and static routing policies to improve network performance and reduce costs. While this has addressed many challenges in enterprise networks, it still lacks the ability to autonomously adjust to network failures, traffic shifts, or security breaches. The future of SD-WAN, however, envisions a more intelligent, self-healing infrastructure where networks can automatically detect, diagnose, and recover from faults without manual input. This model leverages AI and ML to analyze network data, predict potential disruptions, and take proactive measures to maintain optimal performance. In addition, the integration of edge computing, 5G technologies, and Internet of Things (IoT) devices will further enhance SD-WAN’s ability to scale and meet the growing demands of modern enterprises. By shifting towards autonomous and self-healing systems, businesses can achieve more resilient, efficient, and secure networks that not only respond to issues but anticipate and prevent them. This review outlines the key technologies, benefits, and challenges associated with this evolution, offering a vision for a new era of SD-WAN that is both agile and intelligent, capable of delivering unprecedented levels of network reliability and performance.
