why only the first packet retransmission
I did an experiment about retransmission. I am confused that why from 15:23:17 to 15:23:35 only seq 120091 retransmits. In my opinion,seq number from 120627 to 130275 should retransmit too,because their RTOs are time out. But they didn't retransmited until seq 120091 retransmission finished. Does anyone know why? ---------------------------------------------------'DATA-------------------------------
