Section 3.4 says:
7. SYN-SENT <-- <SEQ=400><ACK=101><CTL=SYN,ACK> <-- SYN-RECEIVED 8. ESTABLISHED --> <SEQ=101><ACK=401><CTL=ACK> --> ESTABLISHED Recovery from Old Duplicate SYN Figure 9.
It should say:
7. ESTABLISHED <-- <SEQ=400><ACK=101><CTL=SYN,ACK> <-- SYN-RECEIVED 8. ESTABLISHED --> <SEQ=101><ACK=401><CTL=ACK> --> ESTABLISHED Recovery from Old Duplicate SYN Figure 9.
Notes:
To align with figure 7 in the same section, after TCP A get the SYN+ACK from TCP B, TCP A should enter ESTABLISHED state instead stay in SYN-SENT state.
