TCP Fast Open: initial measurements
Anna Maria Mandalari, Marcelo Bagnulo, Andra Lutu · 2015
In mid-2011 a new mechanism that enables data ex-change during TCP’s initial handshake has been pro-posed by Google. The technique is called TCP Fast Open (TFO). TFO decreases application network la-tency by one full round-trip time. In this paper, we evaluate to which degree the current Internet paths sup-port TFO and how often we encounter cases of inter-ferences from eventual middleboxes along those paths. By expanding the traditional crowdsourcing focus from the human element, we develop a methodology to use a numerous group of end-user devices as measurement vantage points. We find that the 41,3 % of the paths we test allowed for a successful TFO communication. 1.
