Sally Floyd, one of the inventors of Random Early Detection (RED), which helps regulate network traffic, died on August 25 at age 69
In the early 1990s, Dr. Floyd was one of the inventors of Random Early Detection, which continues to play a vital role in the stability of the internet.

Context & Ripple Effects
Sally Floyd's death closes another chapter in a string of obituaries for the people who built the internet's foundations: David J. Farber, whose academic experimental networks helped define the early internet's evolution; David Boggs, who co-invented Ethernet at Xerox PARC; David Walden, who built the Interface Message Processor that switched Arpanet traffic; and Frances Allen, the compiler pioneer and Turing Award winner.
First-order effects
- The networking research community loses one of the last direct links to the early-1990s congestion-control work, with Floyd's Random Early Detection still described as vital to internet stability at the time of her death.
Second-order effects
- Attention on her obituary re-centers RED as living infrastructure rather than history — the queue-management mechanism named in her death notices is the same one running in routers today, raising the visibility of who maintains and extends that lineage.
Third-order effects
- The pattern across these deaths — Farber, Boggs, Walden, Allen, Floyd — marks the transition of the internet's foundational design knowledge from its living inventors to institutions, archives, and the standards they left behind.
The trend: The founding generation that designed the internet's core mechanisms is passing, shifting stewardship of that infrastructure entirely to the institutions and standards they created.
