Dublin, Oct. 29, 2026 (GLOBE NEWSWIRE) -- "Data Center Networking Market Size, Share & Trends Analysis - Global Opportunity Analysis & Industry Forecast (2026-2036)" has been added to ResearchAndMarkets.com's offering.

The global data center networking market is estimated at USD 42.6 billion in 2026 and is projected to reach USD 98.4 billion by 2036, expanding at a CAGR of 8.7% during the forecast period. Growth is being driven by hyperscale data center expansion, cloud computing adoption, AI infrastructure investment, high-speed Ethernet upgrades, and rising demand for programmable network management.

The report evaluates the hardware, Software AG , and communication protocols supporting connectivity among servers, storage systems, computing resources, and external networks. It examines market trends, technological advancements, commercialization strategies, competitive developments, segment performance, and regional growth opportunities across the data center networking value chain.

Market Dynamics

Rapid investment in AI training and inference infrastructure is creating significant demand for high-performance data center networks. AI clusters require thousands of GPUs to exchange data with minimal latency, increasing adoption of high-radix switches, low-latency optical interconnects, specialized AI networking fabrics, and 400G or 800G connectivity. These requirements are generating a high-value growth opportunity for networking equipment, semiconductor, optics, and Software AG suppliers.

The transition from 100G to 400G Ethernet is also supporting multi-year hardware procurement programs, while early 800G deployments continue to gain momentum. These upgrades require operators to replace leaf, spine, and core switches alongside optical transceivers and cabling. At the same time, Software AG -defined networking is enabling centralized and programmable network management, improving automation, multi-tenancy, provisioning, and operational efficiency.

Increasing network scale remains a key industry challenge. Data centers may contain hundreds of thousands of switch ports and millions of virtual connections, raising configuration, monitoring, security, and reliability requirements. This complexity is strengthening demand for AI-based network management platforms that automate network operations, identify performance issues, and predict failures.
