TCP Statistics

	Retransmit Algorithm	The algorithm used to determine the timeout value for
		retransmitting unacknowledged octets.
	Max Retransmit Time	The maximum value permitted by a TCP
		implementation for the retransmission timeout,
		measured in milliseconds.
	Active Opens	The number of times TCP connections have made a
		direct transition to the SYN-SENT state from the
		Closed state.
	Failed Attempts	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.
	Established Conns	The number of TCP connections for which the current
		state is either Established or Close-Wait.
	Output Segments	The total number of segments sent, including those on
		current connections but excluding those containing
		only retransmitted octets.
	Input Errors	The total number of segments received in error (for
		example, bad TCP checksums).
	Min Retransmit Time	The minimum value permitted by a TCP
		implementation for the retransmission timeout,
		measured in milliseconds.
	Max TCP Connections	The total number of TCP connections that the CSS
		supports.
	Passive Opens	The number of times TCP connections have made a
		direct transition to the SYN-RCVD state from the
		LISTEN state.
	Resets	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.
