From Land to Sea to Cloud
By Brian Lavallée – Submarine networks carry over 99% of all telecommunications traffic between continental landmasses making them easily classified as critical infrastructure. There’s also no “Plan B” for these submerged assets, so they’ll continue to act as the jugular veins of intercontinental connectivity for years to come and will thus require constant technology innovation to reliably and securely maintain this pivotal role.
But exactly what traffic is transported back and forth on seabeds around the world? According to respected industry analyst firm TeleGeography, it’s increasingly Data Center Interconnection (DCI) traffic, and LOTS of it.
It’s projected that Internet Content Providers (ICPs) will soon account for the majority of submarine traffic in all regions of the world. Impressive for a group of companies that just over a decade ago, were essentially non-players in the submarine networking market.
Given the astonishing amount of DCI traffic added to traditional wholesale traffic, several new technologies were introduced to address this extraordinary growth, which sits at around 40% CAGR worldwide, according to TeleGeography. more>
