IP ROUTING

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.

Statistical Values

Parameter	Description
Segments Received	The total number of segments received, including those
	received in error. This count includes segments received
	on currently established connections.
Segments Sent	The total number of segments sent, including those on
	current connections but excluding those containing only
	retransmitted octets.
Active Opens	The number of times TCP connections have made a
	direct transition to the SYN-SENT state from the
	CLOSED state.
Failed Connection	The number of times TCP connections have made a
Attempts	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.
Current Connections	The number of TCP connections for which the current
	state is either ESTABLISHED or CLOSE- WAIT.
Receive Errors	The total number of segments received in error (e.g.,
	bad TCP checksums).
Segments Retransmitted	The total number of segments retransmitted - that is, the
	number of TCP segments transmitted containing one or
	more previously transmitted octets.
Passive Opens	The number of times TCP connections have made a
	direct transition to the SYN-RCVD state from the
	LISTEN state.
Reset Connections	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.
