The junctions between different internet networks are close to being overwhelmed, the Finnish telecom equipment company said in a weekly report seen by Bloomberg News.

“Globally, service providers are starting to see the increased strain and are approaching the capacity on some peering links and edge routers,” Nokia said.

But don’t panic yet: Operators can sidestep major jams and outages by rapidly upgrading equipment and adding components at these bottlenecks, according to the company, which likened it to a supermarket hiring more cashiers for busy times.

“They can add more capacity, which is easily done,” Nokia said. “Networks are handling traffic well — so far.”
