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.
