Segment Analysis
By Component: Services Gain Momentum Amid Complexity
Products retained 74.72% of data center networking market revenue in 2025, led by Ethernet switches that transitioned from 100 G to 400 G to satisfy AI workloads. Optical interconnects, storage fabrics, and application delivery controllers reinforced Product dominance but now face slowing unit growth as enterprises focus on architectural simplification. Vendors reported upticks in 51.2 Tbps chassis sales as GPU clusters expanded.
The Services segment is projected to grow at 17.7% CAGR as customers offload design, integration, and lifecycle management of lossless fabrics. Installation services for Priority Flow Control tuning, consulting on congestion metrics, and ongoing managed-fabric subscriptions fuel recurring revenue. Enterprises cite reduced mean-time-to-deploy by 38% after adopting turnkey managed operations, positioning Services as a critical enabler of AI business outcomes.
By End-User: Manufacturing Drives Edge Transformation
IT & Telecommunications captured 35.75% of the data center networking market in 2025 by virtue of hyperscale cloud, CDN, and telco investments that underpin digital-service delivery. Banking, media streaming, and e-commerce workloads dominate regional consumption across metro campuses.
Manufacturing & Industrial will advance at an 18.05% CAGR through 2031 as predictive-maintenance algorithms migrate from centralized clouds to factory-floor micro-data centers. Low-latency Ethernet fabrics link robotics, machine-vision cameras, and MES applications, cutting downtime and energy waste. Edge-native networking contracts have grown 2.4 times since 2023, underpinning sustained demand for compact, fanless 400 GbE leaf switches.
By Data-Center Type: Hyperscalers Lead AI Infrastructure
Colocation operators held 56.45% of 2025 revenue as enterprises pursued asset-light models but insisted on controlling their own layer-2 domains. Retrofit activity focused on liquid cooling loops and higher amperage feeds to accommodate racks exceeding 80 kW.
Hyperscaler and Cloud Service Provider campuses will rise at a 19.05% CAGR, accounting for the largest absolute addition to global optical backbones. AI clusters with 16,000+ GPUs require non-blocking Clos fabrics exceeding 2 Pbps, prompting system integrators to deploy fully integrated leaf-spine-superspine topologies pre-cabled at the factory. The result is an unprecedented pull-through effect for top-of-rack optics and 102.4 Tbps switching silicon.
By Bandwidth: Greater Than 100 GbE Segment Accelerates
Ports between 50 GbE and 100 GbE represented 38.15% of shipments in 2025 as enterprise refresh cycles caught up with hyperscale standards. However, the >100 GbE tier will grow 17.74% annually, driven by the data center networking market need for 400 G leafs and 800 G spines in AI clusters. In comparison, ≤10 GbE ports now concentrate in branch and management networks only.
The >100 GbE expansion correlates with merchant-silicon roadmaps offering 51.2 Tbps and 102.4 Tbps densities. Optoelectronic co-packaging and advanced PAM4 modulation further lower power per bit, partially offsetting rack-level thermal pressures. Early pilots of 1.6 T Ethernet are under evaluation by three hyperscalers for 2027 production clusters.

Detailed country-level analysis extends to Belgium, Nigeria, Canada, and Brazil incorporating local coverage and market participation, as required.
Regulatory Landscape
Data center networking demand is increasingly shaped by cybersecurity, operational resilience, and product compliance regimes that extend beyond operators to equipment and managed-service providers. In the European Union, NIS 2 sets baseline security and supply-chain expectations across critical and important entities, while the Digital Operational Resilience Act (DORA) tightens incident reporting and third-party risk management requirements for covered financial services and their ICT service providers, reinforcing auditability and telemetry in network operations. The EU AI Act (2025) also raises governance expectations for AI systems, influencing how organizations document risk, transparency, and controls for AI workloads running on high-bandwidth fabrics.
Sustainability and hardware-compliance rules are adding parallel constraints on networking refresh cycles. EU Ecodesign and RoHS requirements affect design choices for switches, optics, and power-efficient architectures, increasing the emphasis on energy-per-bit metrics and lifecycle management across multi-vendor environments. Outside Europe, the United States continues to apply a more fragmented approach, including state-level AI-related transparency measures such as in Maryland and Colorado, which feeds into region-specific compliance playbooks for AI infrastructure deployments and the services built around them.
Competitive Landscape
Data center networking market competition is moderate but intensifying as AI optimizations shift value toward lossless fabrics and integrated telemetry. Arista Networks overtook Cisco in Q4 2023 switching revenue within hyperscale accounts by aligning its EOS operating system with AI congestion-control enhancements. NVIDIA capitalized on Spectrum-X to extend its GPU moat into Ethernet, targeting end-to-end AI platform ownership.
Cisco counters through Silicon One integration with NVIDIA’s platforms and by leveraging its enterprise installed base for cross-selling AI-ready fabrics. Juniper Networks’ impending acquisition by HPE signals a strategic move to fuse AI-native routing with edge-to-cloud stacks. Dell and Huawei compete on vertically-integrated racks that pre-stage copper-to-liquid cooling conversions. Start-ups such as Arrcus exploit cloud-neutral routing stacks to win Tier-2 cloud and colocation footprints where agility trumps vendor incumbency. Optical landscape dynamics include Nokia’s purchase of Infinera to create coherent-optics portfolios tuned for metro data-center-interconnect.

Market Opportunities and Future Outlook
AI-optimized fabrics are driving a step change in high-speed Ethernet, creating whitespace for platforms and services that simplify adoption of 800G and 1.6T-class networking in GPU-heavy environments. The opportunity is concentrated in validated, systems-level reference architectures that reduce integration risk across switches, optics, cabling, and operations tooling, a direction reflected in vendor moves toward end-to-end AI infrastructure bundles from Cisco, Arista, and HPE/Juniper. With products still accounting for 74.72% of market revenue in 2025, switch and optical platforms remain central, but lossless Ethernet tuning and congestion management are expanding the addressable scope for installation, integration, and managed-fabric offerings.
Operational automation is becoming a differentiator for east-west traffic patterns and multi-tenant environments where deterministic performance matters. Software-defined networking controllers, observability, and policy automation can expand as tools for congestion detection and QoS adjustments mature, including orchestration that spans on-prem and public cloud connectivity. On the hyperscale side, work on modular interconnect designs and optical switching concepts, including Google research on topologies and optical circuit switching, supports ongoing demand for higher port densities, power-aware designs, and DCI-capable optical interconnects. This aligns with the broader shift toward fabrics that treat networking as part of an AI supersystem rather than a standalone tier.

Data Sources, Market Sizing, and Validation
Desk Research
Desk research was used to set the fact base and define what should be counted as data center networking spend before the model was built. We leaned on public sources such as ITU connectivity statistics, OECD digital economy indicators, World Bank macro series, U.S. Census trade releases for relevant electronics categories, and IEEE and IETF publications that signal technology shifts like 400G and 800G.
We also reviewed vendor annual reports and investor decks, data center association publications, and credible press coverage to understand upgrade cycles, supply constraints, and shipment commentary. Where available, paid subscriptions were used to cross-check company financials and to scan patent activity that can validate the timing of platform transitions. The sources listed here are illustrative only, and many additional public references were used to collect data, validate assumptions, and clarify open questions.
Primary Interviews and Surveys
Primary interviews and surveys helped convert broad demand signals into market-relevant assumptions that can be modeled. We spoke with data center operators, network architects, systems integrators, and component channel participants across APAC, EMEA, and the Americas, so gaps from desk research could be filled and then checked with multiple viewpoints.
Distribution of primary research fieldwork respondents
| Company type | Respondent position | Region |
|---|---|---|
| Top tier: 30% | CXOs: 16% | APAC: 53% |
| Mid tier: 52% | Functional/Unit leaders: 40% | EMEA: 29% |
| Smaller Players: 18% | Managers: 44% | Americas: 18% |
Market-Sizing & Forecasting
Sizing starts with a top-down build where data center footprint growth and upgrade intensity are reconstructed using a demand-pool view, then converted into spend across core networking categories. Inputs that matter in this market include installed and planned data center capacity (MW and floor space proxies), port speed migration (100G to 400G to 800G), switch and router average selling price trends, optics attach rates, and the share of spend routed through managed and integration services.
To keep the model realistic, results are corroborated with selective bottom-up approximations such as sampled price times volume checks for switching ports and transceiver volumes, plus channel feedback on lead times and discounting. When geography or component data is thin, we use conservative interpolation anchored to observable indicators like data center construction activity and cloud capex signals, and then re-check assumptions in follow-up calls. Forecasts are developed using scenario analysis supported by expert input on AI cluster build timing, Ethernet roadmaps, and likely pricing erosion by speed class, then consolidated into a single base case.
Data Validation & Update Cycle
Outputs are validated through multiple checks so that obvious overcounts and missing buckets are removed early. We compare totals against independent signals like data center capex direction, public shipment commentary, and regional build activity, and then anomalies are reviewed by another analyst before sign-off.
If a variance is material, the assumptions that drive it are revisited, and the interview loop is reopened for targeted reconfirmation. The report is refreshed annually, and interim updates are made when major events shift pricing, supply, or deployment pace. Before delivery, a final review pass is completed so clients get the most current view available at that time.
Mordor Intelligence's Global Data Center Networking Market Size Compared Against Other Published Estimates
Published market sizes for data center networking often do not match because counted spend can shift based on what is treated as in-scope networking, which year is used as the base, and how pricing changes are handled for high-speed ports and optics.
Some sources use a broader technology view that can blend adjacent data center technology spend into the networking total. In Mordor Intelligence, the number is limited to networking products, software, and services directly deployed to build and operate data center networks, and it is refreshed with pricing and mix checks tied to 100G to 800G transitions.
Benchmark comparison
| Source | Market Size | Gaps in Research Methodology |
|---|---|---|
| Mordor Intelligence | USD 30.78 B (2025) | |
| Trade Journal A | USD 45.80 B (2025) | Uses a wider definition labeled as data center networking technologies, which can pull in adjacent data center technology categories and a different base-year framing. |
| Global Consultancy B | USD 37.60 B (2024) | Anchors the model to an earlier base year and applies different price and mix assumptions for hardware and software, which can change the implied 2025 level after currency timing and upgrade-cycle normalization. |
The spread in the table mostly comes from scope breadth and base-year choices, and then from how fast pricing is assumed to move as 400G and 800G adoption rises. By keeping the counted spend tied to data center network deployments, and by checking port-speed mix and ASP direction with interview feedback, the estimate stays traceable to practical variables that can be repeated and audited.
