In mid-2011 a new mechanism that enables data exchange during TCP’s initial handshake has been proposed by Google. The technique is called TCP Fast Open (TFO). TFO decreases application network latency by one full round-trip time. In this paper, we evaluate to which degree the current Internet paths support TFO and how often we encounter cases of interferences 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.
