This structure contains statistics for the TCP protocol running on the local computer.

Syntax

typedef struct _MIB_TCPSTATS {
  DWORD dwRtoAlgorithm; 
  DWORD dwRtoMin; 
  DWORD dwRtoMax; 
  DWORD dwMaxConn; 
  DWORD dwActiveOpens; 
  DWORD dwPassiveOpens; 
  DWORD dwAttemptFails; 
  DWORD dwEstabResets; 
  DWORD dwCurrEstab; 
  DWORD dwInSegs; 
  DWORD dwOutSegs; 
  DWORD dwRetransSegs; 
  DWORD dwInErrs; 
  DWORD dwOutRsts; 
  DWORD dwNumConns; 
} MIB_TCPSTATS, *PMIB_TCPSTATS;

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.
