The Internet, itself in constant innovation since its inception, has historically supported unprecedented innovation across the globe, driving considerable growth in technology and commerce.This paper reviews a set of properties set out by Internet experts in 2012, which aimed to capture the unvarying properties that defined the Internet (“the Invariants”).

An early realization was that that the Invariants not only capture an ideal form of the Internet, they describe a generative platform — a platform capable of continuous growth and fostering the expansive development of new things upon itself.

[…]

Notably, several technologies being developed and deployed in today’s Internet don’t conform to those Invariants, and thus are not laying the foundation for similar innovations in the future. With the Invariants in hand, however, we have a tool to evaluate the state of the Internet and any proposed changes that would impact it, and support discussion between and among technologists and policy makers to help ensure that future choices foster a better Internet, aligned with the ideal expressed in the Internet Invariants.

This is “climate change” of the Internet ecosystem: absent concrete action to address the departure of the application infrastructure of the Internet from the ideal outlined in the Invariants, the experience of the Internet going forward will not feature such a rich diversity of solutions to the needs of the world’s population.
