Networking: The AI-Driven Shift to High-Speed Interconnections and Sustainable Bandwidth

Enterprise networking is the transport system for advanced technologies on-premises and in the cloud. The landscape of data  center networking has shifted in the past few years to focus less on cloud computing and direct Internet access, and now is  primarily focused on providing high-speed interconnections for AI workloads. Bandwidth is increasing rapidly as AI models  evolve and require more and more resources to execute in a reasonable amount of time. Innovation in the market must  also embrace sustainability to ensure that development doesn’t outpace the ability of modern data center infrastructure to  provide power and cooling. 

When working on strategy, product, marketing, and sales initiatives, consider intelligence from our expert analysts – planned deliverables for 2026 include:

Welcome

The vision behind everything in Futurum’s Custom Research practice is this: research should show you what is happening, what comes next, and what to do about it. It should be personal to each audience, easy for people to grasp, and structured so LLMs can reason over it accurately. And it should be fast and turnkey; you want answers now, not another project to carry for quarters.

Whether you are defining business, channel, or go-to-market strategy; evaluating vendors or justifying ROI; or commissioning research to fill an emerging market need, we have your back, with a program that answers your questions with the objectivity and credibility to drive real decisions.

To do it, we bring unmatched data to bear: Futurum research, surveys, and market projections; validated market feeds; ETR’s 15 years of insight from 10,000 technology decision-makers; G2’s buyer and user data; and what our analysts hear every day. Add leading primary collection, from AI-moderated voice interviews to surveys and analyst-led interviews, all turnkey, and every project comes out credible, nuanced, and actionable.

And we don’t just drop the results in your lap. For internal work, we provide analyst-led sessions, interactive dashboards, and a range of formats. For market-facing work, Futurum delivers turnkey activation and amplification that actually gets seen, by people and by LLMs, through our media and share of voice. This is research that moves decisions and markets.

We will meet you wherever you are, from a fast-turn brief to a multi-year program, and shape the work to your goals, timeline, and budget. The right program for your moment.

If any of this is useful, I would love to talk.
