Using software-based controllers or application programming interfaces (APIs) to connect with underlying hardware infrastructure and manage traffic on a network, software-defined networking, or SDN, is a networking technique. This approach is distinct from traditional networks, which manage network traffic with specialized hardware components like switches and routers. SDN can use software to build and manage a virtual network or manage conventional hardware. Software-defined networking offers a new method of managing the routing of data packets through a centralized server, while network virtualization allows organizations to divide multiple virtual networks within a single physical network or to connect devices on different physical networks to create a single virtual network.

The global software-defined networking market size was valued at USD 16.23 billion in 2021. It is expected to reach USD 153.70 billion by 2030, growing at a CAGR of 28.37% during the forecast period (2022-2030).

Software-Defined Networking (SDN) is experiencing significant growth and evolution, driven by various trends and advancements in the industry.

Here are some of the latest trends shaping the SDN landscape:

• Network Agility and Simplified Management: As network configurations become less complex, organizations are looking for network topologies that make it easier to manage a variety of workloads.

• 5G Technology Integration: SDN skills are essential for managing the sophisticated network features and variety of use cases that 5G networks bring as the technology spreads globally.

• Geographical Highlight: With business behemoths and scholarly know-how propelling industry breakthroughs, the United States distinguishes itself as a leader in SDN innovation. SDN, however, has a worldwide impact; adoption has been examined in a number of locations.

• Kubernetes with Container-Managed Infrastructure: Kubernetes and container-based infrastructure are increasingly integrated in SDN environments, helping to improve network efficiency and manage workloads.

• SD-WAN Extension for Requirements in Remote Work: Software Defined Wide-Area Networks (SD-WAN), which improve broadband connectivity, application performance, and access to workplace applications for remote workers, have become more popular as a result of the growth in remote work.

• Deployment of Cloud-Native Applications: In order to facilitate dynamic resource allocation inside cloud environments and improve speed and agility, programmable network infrastructures like SDN are becoming increasingly necessary as cloud-native applications are deployed.

• Network virtualization: This technique improves flexibility and scalability by enabling the creation of virtual networks that are independent of actual hardware.

• By using Network Functions Virtualization (NFV), network functions that are typically handled by specialized hardware appliances can be virtualized, increasing efficiency and reducing costs.

• Software-Defined WAN (SD-WAN): The use of SD-WAN technology to improve wide-area network control and management, which is especially advantageous for purposes including remote work and better connectivity.

• Cloud-Native SDN Solutions: These new SDN offerings enable enterprises to effectively manage and optimize their networks by providing scalability, agility, and seamless integration with cloud environments.

• 5G Technology Integration: Managing sophisticated network components and a variety of use cases offered by 5G networks through the integration of SDN capabilities with 5G technology will propel growth and innovation in the SDN market.

• SDN has historically been linked to telecommunications firms, who greatly profit from adaptable networks that can be rapidly set up to satisfy shifting client demands. SDNs are becoming more and more common in industry, nevertheless. Intel is implementing SDN in its semiconductor manufacturing plants. 41% of manufacturers rank the ability to quickly adjust bandwidth capacity as their main justification for investing in SDN.

• Growing Adoption of SDN: By dividing the control plane from the data plane and enabling centralized management and orchestration, SDN allows enterprises to achieve more agility and scalability in their networks.

• Integration with Emerging Technologies: SDN is being combined with edge and cloud computing, enabling businesses to build automated and more effective network infrastructures that meet the needs of contemporary applications.

• As 5G networks are implemented, SDN will be essential for dynamically controlling network traffic, maximizing resource use, and guaranteeing smooth connectivity for a wide range of devices.

• Increase in SD-WAN Solutions: SD-WAN solutions, which are especially useful in remote work situations, use SDN principles to optimize wide area network management. This results in increased connectivity, cost effectiveness, and application performance.

• Collaborations with Cloud Service suppliers: To offer integrated solutions that combine SDN capabilities with cloud services for a unified networking experience, there is a trend of cooperation and collaborations between SDN suppliers and significant cloud service providers.

• Security is a Key Focus: SDN trends place a strong emphasis on security, with a particular focus on integrating strong security features into SDN architectures to better threat mitigation and detection as well as the deployment of zero-trust network policies for increased network resilience.
