The proposed Death flag, or DTH for short, uses the fourth flag bit in the TCP header to indicate likely termination of the TCP session.

The flag allows applications to prepare for abrupt session terminations. Network engineers find this feature helpful in identifying the one or more root causes of TCP RSTs. Critical end users can use the information to better understand TCP narratives.
