    Hi Miguel!
    I don't understand in the exercise 1 how you get the value '3Ttx' and what does it mean.
    Could you please explain it? Thanks in advance.

    Ttx stands for transmission time (of a single packet)

    3Ttx is three times transmission time (which is what is left for the last packet to be forwarded from first router to B).
