Sally Floyd

from Wikipedia, the free encyclopedia

Sally Jean Floyd (born May 20, 1950 in Charlottesville , Virginia ; died August 25, 2019 in Berkeley , California ) was an American computer scientist best known for her work on computer networks .

She was previously affiliated with the International Computer Science Institute at Berkeley. In 2009 she retired. She is best known for her work on internet congestion control.

Live and act

Floyd received her bachelor's degree in sociology from the University of California, Berkeley in 1971. She received her master's degree in computer science in 1987 and her PhD in 1989, also at the University of California, Berkeley.

She is known in the field of congestion control as the inventor of the active queue management of Random Early Detection (RED) and thus founded the field of Active Queue Management (AQM) with Van Jacobson . Almost all routers use RED or something designed from it to manage network congestion. Floyd developed the method commonly used today of adding delay jitter to message timers to avoid synchronization.

She was involved in the Internet Architecture Board and in 2007 was one of the ten most cited researchers in computer science.

Publications

  • In 1997, Floyd and Vern Paxson identified the lack of knowledge of network topology as the main obstacle to understanding how the Internet works. In 2001 that paper, Why We Don't Know How to Simulate the Internet , was republished as Difficulties in Simulating the Internet and received the William R. Bennett Prize Paper Award from the IEEE Communications Society.
  • Floyd is co-author of the standard for TCP Selective Acknowledgment (SACK), Explicit Congestion Notification (ECN), the Datagram Congestion Control Protocol (DCCP) and TCP Friendly Rate Control (TFRC).

Awards

  • She received the IEEE Internet Award in 2005 and the ACM SIGCOMM Award in 2007 for her contributions to congestion control.
  • William R. Bennett Prize Paper Award from the IEEE Communications Society for Difficulty Simulating the Internet by Floyd and Vern Paxson
