'''Blue''' is an [[scheduling discipline]] for the [[network scheduler]] developed by graduate student Wu-chang Feng for Professor [[Kang G. Shin]] at the [[University of Michigan]] and others at the [[Thomas J. Watson Research Center]] of [[IBM]] in 1999.<ref name="mich">{{Cite journal |title=BLUE: A New Class of Active Queue Management Algorithms |author1=Wu-chang Feng |author2=Dilip D.

===Resilient stochastic fair Blue===

Many scheduling algorithms, including the fairness-aimed ones, are notably vulnerable to spoofing [[distributed denial-of-service]] (DDoS) attacks. A resilient stochastic fair Blue (RSFB) algorithm was proposed in 2009 against spoofing DDoS attacks. The basic idea behind RSFB is to record the responsive normal TCP flows and rescue their dropped packets. RSFB algorithm is effective in preserving the TCP throughput in the presence of spoofing DDoS attacks.<ref name=RSFB>{{Cite journal |authorauthor1= Changwang Zhang, |author2=Jianping Yin, and |author3=Zhiping Cai |last-author-amp=yes |url= http://sites.google.com/site/cwzhangres/home/files/RSFBaResilientStochasticFairBluealgorithmagainstspoofingDDoSattacks.pdf |title= RSFB: a Resilient Stochastic Fair Blue algorithm against spoofing DDoS attacks |work= International Symposium on Communication and Information Technology (ISCIT) |year= 2009 |pages= 1566–1567 |isbn= 978-1-4244-4521-9 |accessdate= June 8, 2013 }} [http://portal.acm.org/citation.cfm?id=1789954.1790341 Abstract]</ref>
