MIB-II Object Types
The TCP Group
Implementation of the TCP group is mandatory for all systems that implement the TCP.
Note:
tcpRtoAlgorithm
Syntax
Value
Integer
Access
Read-only
Status
Mandatory
Description
The algorithm used to determine the time-out value used for retransmitting unacknowledged octets.
tcpRtoMin
Syntax
Integer
Access
Read-only
Status
Mandatory
Description
The minimum value permitted by a TCP implementation for the retransmission time-out, measured
in milliseconds.
Note:
1-46
Instances of object types that represent information about a particular TCP connection are
transient; they persist only as long as the connection in question.
Declaration
Description
1 (other)
None of the following
2 (constant)
A constant rto
3 (rsre)
MIL-STD-1778, Appendix B
4 (rsre)
Van Jacobson's algorithm [10]
More refined semantics for objects of this type depend upon the algorithm used to
determine the retransmission time-out. In particular, when the time-out algorithm is rsre
(3), an object of this type has the semantics of the LBOUND quantity described in RFC
793.
