Stefan Savage (born 1969) is an American computer science researcher, currently a Professor in the Systems and Networking Group at the University of California, San Diego.
That same year, Savage published "Sting", a paper and software tool that presented a mechanism to abuse quirks in the TCP protocol to allow a single party to infer bidirectional packet loss, a valuable contribution to traffic measurement.
[3] In 2000, Savage's team published Practical Network Support for IP Traceback, which proposed a simple stochastic extension to internet routers that would enable them to trace floods of traffic back to their origin.
[3] In 2001, Savage, with colleagues at UCSD and CAIDA, published Inferring Internet Denial-of-Service Activity, which introduced the idea of the network telescope and provided major empirical results regarding DDOS attacks.
[6] In 2005, Ishwar Ramani and Stefan Savage developed Syncscan algorithm that cuts the time needed to switch between Wi-Fi access points.
