TCP Statistics

The Transmission Control Protocol (TCP) provides highly reliable
host-to-host connections in packet-switched networks, and is used in
conjunction with IP to support a wide variety of Internet protocols.

Table 17-6 TCP Statistics

Description
The total number of segments received, including
those received in error. This count includes segments
received on currently established connections.
The total number of segments sent, including those
on current connections but excluding those
containing only retransmitted octets.
The number of times TCP connections have made a
direct transition to the SYN-SENT state from the
CLOSED state.
The number of times TCP connections have made a
direct transition to the CLOSED state from either the
SYN-SENT state or the SYN-RCVD state, plus the
number of times TCP connections have made a direct
transition to the LISTEN state from the SYN-RCVD
state.
The number of TCP connections for which the
current state is either ESTABLISHED or CLOSE-
WAIT.
The total number of segments received in error (e.g.,
bad TCP checksums).
The total number of segments retransmitted - that is,
the number of TCP segments transmitted containing
one or more previously transmitted octets.
The number of times TCP connections have made a
direct transition to the SYN-RCVD state from the
LISTEN state.
The number of times TCP connections have made a
direct transition to the CLOSED state from either the
ESTABLISHED state or the CLOSE-WAIT state.
