Encyclopedia
Sally Floyd was a computer scientist at the International Computer Science Institute
in Berkeley, California
. She retired in 2009. She is best known for her work on Internet congestion control. She was the inventor of Random Early Detection
active queue management scheme, a co-author on the standard for TCP Selective acknowledgement (SACK), Explicit Congestion Notification
(ECN), the Datagram Congestion Control Protocol
(DCCP) and TCP Friendly Rate Control
(TFRC).
Dr. Floyd received a BA in Sociology from the University of California - Berkeley in 1971. She received an MS in Computer Science in 1984 and a PhD in 1987, both from UC - Berkeley.
She received the IEEE Internet Award
in 2005 and the ACM SIGCOMM Award
in 2007 for her contributions to congestion control.

active queue management scheme, a co-author on the standard for TCP Selective acknowledgement (SACK), Explicit Congestion Notification
Explicit Congestion Notification
Explicit Congestion Notification is an extension to the Internet Protocol and to the Transmission Control Protocol and is defined in RFC 3168 . ECN allows end-to-end notification of network congestion without dropping packets. ECN is an optional feature that is only used when both endpoints...
(ECN), the Datagram Congestion Control Protocol
Datagram Congestion Control Protocol
The Datagram Congestion Control Protocol is a message-oriented Transport Layer protocol. DCCP implements reliable connection setup, teardown, Explicit Congestion Notification , congestion control, and feature negotiation. DCCP was published as RFC 4340, a proposed standard, by the IETF in March,...
(DCCP) and TCP Friendly Rate Control
TCP Friendly Rate Control
TCP-Friendly Rate Control is a congestion control mechanism designed for unicast flows operating in an Internet environment and competing with TCP traffic. The goal is to compete fairly with TCP traffic on medium timescales, but to be much less variable than TCP on short timescales.TCP congestion...
