The global software-defined networking market size was valued at USD 35.67 billion in 2025 and is projected to grow from USD 42.93 billion in 2026 to USD 189.08 billion by 2034, registering a CAGR of 20.36% during the forecast period from 2026 to 2034. North America dominated the software-defined networking market with a market share of 38.5% in 2025.
To make networks more manageable and flexible, software-defined networking is a networking strategy that enables networks to be intelligently and centrally controlled or programmed with the aid of software-based controllers or application programming interfaces (APIs). The network resources are optimized, and networks are swiftly adjusted to new applications, commercial demands, and data traffic. Additionally, it provides a wealth of benefits for businesses, like the ability to respond more quickly to problems and outages for improved network availability, increased flexibility & accelerated time-to-market for new applications, and programmability for networking that enables businesses to automate their network functions and lower operating costs. Traditional networks rely on physical infrastructures like switches and routers for connections and proper operation. On the other hand, a software-based network enables the user to regulate the distribution of resources at the level of the virtual network via the control plane.

Agentic AI Is Moving SDN Toward More Autonomous Network Operations
The Software-Defined Networking Market is moving beyond rule-based automation toward AI agents that can interpret telemetry, diagnose problems, recommend changes, and automate selected network actions. This strengthens the original SDN model because centralized software control can now respond more intelligently to changing network conditions. Enterprises can use these capabilities to reduce repetitive configuration work, identify root causes faster, and optimize paths or policies before users experience major disruption. The trend is particularly relevant across data centers, campuses, branches, and service-provider networks where manual management becomes difficult at scale. Vendors are consequently combining SDN controllers with AIOps, real-time observability, intent validation, and automated remediation.
In February 2026, Cisco expanded AgenticOps across its networking portfolio, adding agentic workflows for campus, branch, industrial, data-center, and service-provider environments.
AI Data Centers Require Programmable High-Performance Network Fabrics
Rapid expansion of AI infrastructure is increasing demand for software-controlled networking capable of handling large, changing traffic flows between thousands of accelerators. AI training requires high bandwidth, low latency, congestion control, telemetry, and predictable performance, making static network management increasingly unsuitable. Programmable fabrics can automatically configure paths, monitor network conditions, and optimize traffic according to workload requirements. NVIDIA's Spectrum-X platform, for example, combines Ethernet switching, SuperNICs, adaptive routing, telemetry, and software to improve AI networking performance by 1.6 times compared with off-the-shelf Ethernet. As AI clusters expand across facilities, SDN becomes increasingly valuable for coordinating complex networks and maintaining efficient use of expensive computing infrastructure.
In October 2025, Meta and Oracle announced adoption of NVIDIA Spectrum-X Ethernet switches for large-scale AI data-center networks, including open networking deployment within Meta's ecosystem.
Migration from Existing Networks Creates Integration and Skills Barriers
SDN adoption can be slowed by the difficulty of replacing or integrating traditional network environments. Enterprises often operate equipment from several generations and vendors, along with existing automation scripts, security policies, management platforms, and operational procedures. Moving toward centralized, intent-based control requires accurate network models and integration with this installed infrastructure. Organizations also need engineers who understand APIs, automation, telemetry, overlays, and software-driven operations alongside conventional networking. These requirements increase migration time and implementation risk. Even modern SDN platforms offer different licensing tiers and multivendor capabilities, meaning organizations must carefully assess functionality, hardware compatibility, staff skills, and operational costs before expanding software-defined management across large environments.
In May 2025, Maynooth University reported using Juniper Apstra to automate an EVPN-VXLAN data-center fabric while managing modernization with a networking team of only three people.
Multi-Site AI Fabrics Create a New Scale-Across Networking Opportunity
An important opportunity is emerging as AI infrastructure expands beyond individual data centers. Power, space, cooling, and computing constraints can prevent organizations from placing every accelerator in one building. Software-defined networking can coordinate traffic across geographically separated facilities, allowing distributed computing resources to operate more like one logical infrastructure pool. This creates demand for topology-aware routing, congestion control, centralized policies, real-time telemetry, and automated multi-site orchestration. SDN vendors can therefore extend beyond conventional data-center fabrics into inter-data-center networking designed specifically for distributed AI. Providers that maintain predictable performance across sites can capture demand from cloud companies and enterprises building increasingly large AI computing environments.
In August 2025, NVIDIA introduced Spectrum-XGS Ethernet for connecting distributed data centers into unified AI super-factories and announced CoreWeave as an adopter of the scale-across technology.
Cybersecurity Requirements Are Making Programmable Networks Harder to Govern
Centralized programmability improves network agility but also makes security governance critical. SDN controllers and automation systems can influence large portions of infrastructure, meaning configuration errors, compromised credentials, vulnerable APIs, or unsafe automated changes can have broad consequences. Organizations therefore need strong access controls, cryptography, asset management, incident handling, supply-chain security, continuous monitoring, and evidence that cybersecurity policies are actually enforced. Regulatory requirements add another layer of complexity for cloud providers, data centers, managed service providers, and other digital infrastructure operators. SDN platforms must consequently combine automation with policy validation, segmentation, auditability, and secure change management rather than focusing only on faster network configuration and centralized control.
In June 2025, ENISA issued NIS2 technical implementation guidance covering network security, incident handling, access control, cryptography, supply-chain security, and asset management for regulated digital-infrastructure organizations.
