Table 11. TCP Statistics
Name Description
RtoAlgorithm
The algorithm used to determine the timeout value used for retransmitting
unacknowledged octets.
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 ATLAS 800 Series 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.
