How Ciena keeps the internet online, with CEO Gary Smith

Bandwidth Growth

Bandwidth growth has been a consistent trend over the past two decades, with annual increases of 20-30%, driven by the proliferation of connected devices and applications. Gary Smith notes that the advent of AI could further accelerate this growth to 30-40% per year, as more data centers come online to support AI-driven applications 1. He emphasizes the challenge of predicting the exact impact of AI on bandwidth demand, but acknowledges a significant uptick in cloud traffic due to the need for interconnected data centers 2.

We're underestimating the amount of traffic that's going to be there.

This growth is not just about current applications like ChatGPT but extends to potential future uses in fields like medicine, which require substantial bandwidth.

   

AI's Network Impact

The impact of AI on network infrastructure presents both challenges and opportunities. Gary Smith explains that while fiber optics remain a constant, the technology at the ends of these fibers is where significant advancements occur, allowing for massive scaling without the need for new fiber installations 3. He also highlights the geopolitical dynamics affecting internet architecture, noting that different countries are beginning to diverge in their network designs, which could influence the global internet landscape 4.

We're underestimating the amount of traffic and bandwidth that will be required.

This divergence is particularly relevant as AI applications demand more bandwidth and power, potentially leading to an exponential rise in network capacity needs.
