Released in 2019, Cisco’s Silicon One architecture was the result of a massive $1 billion investment. And it represented the industry’s only scalable, programmable, and unified networking architecture. From the very beginning, Cisco’s vision was bold: to completely rethink what the internet could do and how accessible it could be.

Since then, Silicon One has delivered rapid improvements in speed, bandwidth, low latency, and energy savings. Today it powers hyperscale, data centers, service provider, and enterprise networks, across a wide range of Cisco products that are enabling and securing the AI revolution.

Here are some key moments that shaped this remarkable journey, from the first sparks of inspiration to the recent release of the Silicon One P200, which is enabling the rapid acceleration of the AI era.
