Members
dwRtoAlgorithm
The retransmission time-out algorithm in use. The following table shows the possible values. This member can be one of these values.Value Description MIB_TCP_RTO_CONSTANT
Constant Time-out
MIB_TCP_RTO_RSRE
MIL-STD-1778 Appendix B
MIB_TCP_RTO_VANJ
Van Jacobson's Algorithm
MIB_TCP_RTO_OTHER
Other
- dwRtoMin
The minimum retransmission time-out value in milliseconds.
- dwRtoMax
The maximum retransmission time-out value in milliseconds.
- dwMaxConn
The maximum number of connections. If this member is -1, the maximum number of connections is dynamic.
- dwActiveOpens
The number of active opens. In an active open, the client is initiating a connection with the server.
- dwPassiveOpens
The number of passive opens. In a passive open, the server is listening for a connection request from a client.
- dwAttemptFails
The number of failed connection attempts.
- dwEstabResets
The number of established connections that have been reset.
- dwCurrEstab
The number of currently established connections.
- dwInSegs
The number of segments received or transmitted.
- dwOutSegs
The number of segments transmitted. This number does not include retransmitted segments.
- dwRetransSegs
The number of segments retransmitted.
- dwInErrs
The number of errors received.
- dwOutRsts
The number of segments transmitted with the reset flag set.
- dwNumConns
The cumulative number of connections.
