[Bro-Dev] TCP RTT estimation

[Juhoon Kim]

[Sender]        [Monitor]-------------(a)------>[Receiver]
[Sender]<-------[Monitor]<--------ack-of-(a)----[Receiver]
[Sender]--(b)-->[Monitor]

I thought that the acknowledgement number of the second component
(ack-of-a) is always the same with the sequence number of the next
segment (b). That is how I wanted to identify the segment (b).

However, it seems like it is not always the case. I will study more
about this.

Maybe I underestimate this problem. I will restart from the paper. 

Thanks.
