Data Center Networking Market

The rising adoption of AI, high-performance computing (HPC), and data-intensive applications is further accelerating demand for advanced Ethernet- and InfiniBand-based networking solutions. At the operational level, organizations are prioritizing automation, intent-based networking, and network telemetry to improve performance assurance and reduce manual configuration complexity. Collectively, these trends are redefining data center networking as a foundational infrastructure layer, critical for ensuring scalability, resilience, and performance efficiency in modern digital enterprises.

The data center networking market is expected to grow at a CAGR of 16.5% during the forecast period, from USD 55.64 billion in 2025 to USD 139.08 billion in 2031. The global data center networking market is witnessing steady expansion, driven by rapid cloud adoption, hyperscale data center buildouts, and increasing east-west traffic generated by virtualized and containerized workloads. Enterprises are modernizing network architectures to support high-bandwidth, low-latency, and scalable connectivity across on-premises, colocation, and multi-cloud environments. The shift toward leaf-spine architectures, 400G/800G switching, and software-defined networking is enabling greater agility, improved traffic visibility, and simplified network operations.
