“Enterprises have shifted connectivity to the internet, mostly with DIA. This changes the security environment away from private MPLS to the best-efforts public internet.”

Last week, Senior Manager of Enterprise Research Greg Bryan joined Ciena's Brian Lavallée for a live webinar all about submarine cables and security.

For his part, Greg described how the enterprise network has shifted in the last few years, how carriers and enterprises have responded to these changes, and why geography matters in network security.

Many retail service providers, such as mobile operators, MVNOs, and cable broadband providers, rely heavily on wholesale carriers to transport and terminate their customers’ international calls.

Wholesale carriers terminated approximately 257 billion minutes of traffic in 2022, down 5% from 2021. Wholesale traffic declined at an average rate of 1% per year over the past ten years, compared to a -2% CAGR for overall traffic. Wholesale carriers terminated nearly three-fourths (72%) of international traffic in 2022, up from 70% the year before.

Traffic to mobile phones in emerging markets has spurred expansion in wholesalers' share of the overall market. In 2022, wholesale carriers terminated over 87% of traffic to Sub-Saharan Africa and South America. In contrast, wholesale carriers terminated only 56% of traffic to Western Europe.

How? Is the network getting faster?

Not quite. Think bigger highway, not faster cars.
