time sequence(tcp trace)

retag add tags

Hi , I am a newbie

Recently I learning the time sequence (tcptrace)

Why one of the segment blocks of the SACK option field will be removed without being confirmed ?

SACK's segment block should be removed after the missing segment is confirmed.

However, in the following case, when the sender loses the packet again, the segment block of the SACK option is one less segment.

Please help answer , thank you so much
