Retaining key parameters after a transmission control protocol (TCP) session flap

A network device, comprising:

• one or more memories;
• and
• one or more processors to:
• monitor a transmission control protocol (TCP) session with an other network device;
• identify a TCP header, a socket of the TCP session, and one or more of a set of ingress packets or a set of egress packets;
• inspect the TCP header, the socket, and the one or more of the set of ingress packets or the set of egress packets to identify session information,
• wherein the session information includes negotiated TCP options associated with the TCP session and one or more of a finish packet or a reset packet;
• detect a TCP session flap based on the session information including the one or more of the finish packet or the reset packet;
• store, in a dead TCP session list, data identifying the session information based on the TCP session flap being detected;
• and
• identify, based on the negotiated TCP options, an out-of-sync issue,
• wherein the out-of-sync issue corresponds to the network device having selective acknowledgement enabled and the other network device not having selective acknowledgement enabled.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
• monitor a transmission control protocol (TCP) session with an other network device;
• identify a TCP header, a socket of the TCP session, and one or more of a set of ingress packets or a set of egress packets;
• inspect the TCP header, the socket, and the one or more of the set of ingress packets or the set of egress packets to identify session information,
• wherein the session information includes negotiated TCP options associated with the TCP session and one or more of a finish packet or a reset packet;
• detect a TCP session flap based on the session information including the one or more of the finish packet or the reset packet;
• store, in a dead TCP session list, data identifying the session information based on the TCP session flap being detected;
• and
• utilize, based on the TCP session flap being detected, the negotiated TCP options to identify an out-of-sync issue,
• wherein the out-of-sync issue corresponds to the network device having selective acknowledgement enabled and the other network device not having selective acknowledgement enabled.
