LABEL
DESCRIPTION
tcpRtoAlgorithm
This field displays the algorithm used to determine the timeout value that is
used for retransmitting unacknowledged octets.
tcpRtoMin
This field displays the minimum timeout (in milliseconds) permitted by a
TCP implementation for the retransmission timeout. 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.
tcpRtoMax
This field displays the maximum timeout (in milliseconds) permitted by a
TCP implementation for the retransmission timeout. 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.
