What one exec describes as “the most important deployment” in telecom historical past is underway to supply the bandwidth required to run the data- and power-hungry expertise
Misplaced within the headlines trumpeting the astounding dimension and value tags of tomorrow’s information facilities—$200 billion? $500 billion??—is the query of join all of them. Whereas AI’s burning wants for ever extra information, compute, and power dominate tech trade discourse, one piece of the infrastructure puzzle has been all however taken without any consideration: bandwidth. Not anymore. A complete transformation of the web’s bodily structure—from the fiber-optic cables to the longer term websites of knowledge facilities—is at present underway, pushed by the unprecedented calls for of AI workloads.
This overhaul of the web’s plumbing requires greater than merely constructing greater pipes. The networks underpinning cloud computing for the previous 20 years are essentially unsuited to AI’s distinctive calls for. The purpose-to-point infrastructure that served internet and cloud functions so effectively are proving insufficient for the complicated mesh of connections AI requires, during which hyperscalers’ information facilities should shuttle huge volumes of knowledge between their clients’ clouds and places and themselves, with the path and throughput liable to vary on a dime relying on enterprise wants and technique. A community comprised of some giant threads crisscrossing the nation isn’t going to chop it; what’s wanted is a material binding each node collectively.
“How are we going to construct the mass-scale, low-latency, highly-reliable connectivity to assist the way forward for AI?” asks Kye Prigg, govt vp of enterprise operations at Lumen Applied sciences, the place he oversees the telco’s community growth. Lumen’s reply is to put greater than 20,000 miles of state-of-the-art fiber-optic cable, and successfully double its intercity miles throughout the U.S. A whole lot of building crews will construct lots of of future relay stations in what Prigg modestly describes as “one of many largest—if not the largest—fiber deployments occurring in telecom worldwide proper now.”
A New Method to Community Design
Not like the broadband growth of a era in the past, at the moment’s buildout is designed to fulfill the wants of a essentially totally different web. Whereas conventional cloud computing usually manages data shifting between organizations’ personal methods and particular person information facilities, AI workloads demand intense communication between firms’ respective clouds and even between hyperscalers. “With cloud-to-cloud, you’re going to have heavy information flows throughout networks,” Prigg says. This shift not solely requires elevated capability, but in addition a brand new strategy to community design optimized for point-to-point visitors at epic scale.
This reboot begins with the cables themselves. Final yr, Lumen partnered with Corning to make the most of their fiber-optic cables with dramatically greater density than earlier generations. Whereas older variations usually comprise fewer than 200 glass strands per cable, new ones will pack 800 to 1,700 strands into smaller circumferences engineered to suit commonplace pipes. This is not going to solely decrease community latency—essential to real-time responsiveness—but in addition speed up rollout by way of current infrastructure.
Wavelengths On Demand
Lumen is trying to ship much more buyer advantages from its optical relays, which will likely be situated each 50 miles alongside main routes. Many of those “mini–data-center sign boosters,” as Prigg describes them, could have expertise out there to provision and reprogram bandwidth on the fly, enabling clients to connect with an enormous ecosystem of knowledge facilities and cloud service suppliers and thereby easing complexities of multicloud environments and AI functions.
The corporate can also be preserving a big quantity of darkish fiber for itself. Having this capability, Prigg explains, means “an enterprise that desires to mild up fiber can get it just about on demand—we’re speaking about wavelengths on demand.” This represents a departure from the trade’s follow of ready for orders earlier than breaking floor. “That usually takes months and months,” he provides, “so we’re going to have it there already, good to go from Level A to Level B to Level Z.”
Which is an efficient factor, as a result of—in one other break from cloud computing—each hyperscaler’s calls for are totally different in their very own means. “They need totally different information facilities to have totally different connections,” Prigg says. “A few of them wish to buy bandwidth from us and light-weight it up themselves, and a few of them need us to do the entire thing, as a result of they don’t see operating an optical community as a core competence. There are all totally different flavors.”
A Race to Energy
Lastly, the geography of this new community is being formed by an surprising issue: entry to power, relatively than right-of-way. “It’s a race to energy, actually,” Prigg says. “We’re beginning to see explicit corridors opening up the place there’s entry to extra energy within the grid, and these are the places which might be being checked out for these future information facilities.”
With “vital offers within the pipeline,” in Prigg’s phrases, past the preliminary $8.5 billion in AI-related offers the corporate has already secured, Lumen is constructing capability far past present necessities—an enormous wager on AI’s transformative potential harking back to the broadband growth that laid the groundwork for the cloud. However which may be the one factor they’ve in frequent. “That is the most important one I’ve finished in my 30 years within the trade,” he says.
