TCP_ESTATS_FINE_RTT_RW_v0 structure

The TCP_ESTATS_FINE_RTT_RW_v0 structure contains read/write configuration information for extended TCP statistics on fine-grained round-trip time (RTT) estimation statistics for a TCP connection.

Syntax


typedef struct _TCP_ESTATS_FINE_RTT_RW_v0 {
  BOOLEAN EnableCollection;
} TCP_ESTATS_FINE_RTT_RW_v0, *PTCP_ESTATS_FINE_RTT_RW_v0;

Members

EnableCollection

A value that indicates if extended statistics on a TCP connection should be collected for fine-grained RTT estimation statistics.

If this member is set to TRUE, extended statistics on the TCP connection are enabled. If this member is set to FALSE, extended statistics on the TCP connection are disabled.

The default state for this member when not set is disabled.

Remarks

The TCP_ESTATS_FINE_RTT_RW_v0 structure is used as part of the TCP extended statistics feature available on Windows Vista and later.

The TCP_ESTATS_FINE_RTT_RW_v0 is defined as version 0 of the structure for read/write configuration information on fine-grained round-trip time estimation statistics for a TCP connection.

Extended TCP statistics on extended path measurement information for a TCP connection are enabled and disabled using this structure and the SetPerTcp6ConnectionEStats and SetPerTcpConnectionEStats functions when TcpConnectionEstatsFineRtt is passed in the EstatsType parameter.

The TCP_ESTATS_FINE_RTT_RW_v0 structure is retrieved by calls to the GetPerTcp6ConnectionEStats or GetPerTcpConnectionEStats functions when TcpConnectionEstatsFineRtt is passed in the EstatsType parameter.
