RtoAlgorithm
The algorithm used to determine the timeout value used for
retransmitting unacknowledged octets.

rsre(3)       MIL-STD-1778, Appendix B

Enumerations:
  • other (1)
  • constant (2)
  • rsre (3)
  • vanj (4)
RtoMin
The minimum value permitted by a TCP implementation for the
retransmission timeout, measured in milliseconds.  More
refined semantics for objects of this type depend upon the
algorithm used to determine the retransmission timeout.  In
particular, when the timeout algorithm is rsre(3), an object
of this type has the semantics of the LBOUND quantity
described in RFC 793.
RtoMax
The maximum value permitted by a TCP implementation for the
retransmission timeout, measured in milliseconds.  More
refined semantics for objects of this type depend upon the
algorithm used to determine the retransmission timeout.  In
particular, when the timeout algorithm is rsre(3), an object
of this type has the semantics of the UBOUND quantity
described in RFC 793.
MaxConn
The limit on the total number of TCP connections the entity
can support.  In entities where the maximum number of
connections is dynamic, this object should contain the value
-1.
ActiveOpens
The number of times TCP connections have made a direct
transition to the SYN-SENT state from the CLOSED state.
PassiveOpens
The number of times TCP connections have made a direct
transition to the SYN-RCVD state from the LISTEN state.
AttemptFails
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.
EstabResets
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.
CurrEstab
The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT.
InSegs
The total number of segments received, including those
received in error.  This count includes segments received on
currently established connections.
OutSegs
The total number of segments sent, including those on
current connections but excluding those containing only
retransmitted octets.
RetransSegs
The total number of segments retransmitted - that is, the
number of TCP segments transmitted containing one or more
previously transmitted octets.
InErrs
The total number of segments received in error (e.g., bad
TCP checksums).
OutRsts
The number of TCP segments sent containing the RST flag.
