The most annoying advertisement that I have ever seen is a video ad of the game Dead by daylight . I was playing a game on my mobile, and came across this ad. The audio and visual nearly gave me a heart attack. I'm not a fan of horror genre. This unexpected ad, especially the audio, is so annoying that I turn off the audio completely on my phone to avoid any future nasty surprises like this.
RTT is short for round-trip time, the time required for a network communication to travel from the source to the destination and back. RTT is used by some routing algorithms to aid in calculating optimal routes.
