More than 15 years ago the cover story of ACM netWorker magazine discussed the dawn of the stupid network – an architecture with smart edge nodes and simple packet forwarding code. Obviously we learned nothing in all those years – we’re still having the same discussions.
The telcos seemed to "fall asleep at the switch" at the core of their network.
"Keep it simple, stupid," or KISS, is an engineering virtue. The Intelligent Network, however, is anything but simple; it is a marketing concept for scarce, complicated, high-priced services.
The Intelligent Network impedes innovation. Existing features are integrally spaghetti-coded into the guts of the network, and new features must intertwine with the old.
Infrastructure improvements are rapidly making the telcos' Intelligent Network a distinctly second-rate choice. The bottom line, though, is not the infrastructure; it is the innovation that the Stupid Network unleashes.
The whole article is well worth reading, more so considering it’s over 15 years old and still spot-on.
