The TCP_ESTATS_BANDWIDTH_RW_v0 structure contains read/write configuration information for extended TCP statistics on bandwidth estimation for a TCP connection.
A value that indicates if extended statistics on a TCP connection should be collected for outbound bandwidth estimation.
If this member is set to TcpBoolOptEnabled, extended statistics on the TCP connection for outbound bandwidth estimation are enabled. If this member is set to TcpBoolOptDisabled, extended statistics on the TCP connection for outbound bandwidth estimation are disabled. If this member is set to TcpBoolOptUnchanged, extended statistics on the TCP connection for outbound bandwidth estimation are left unchanged.
The default state for this member when not set is disabled.
A value that indicates if extended statistics on a TCP connection should be collected for inbound bandwidth estimation.
If this member is set to TcpBoolOptEnabled, extended statistics on the TCP connection for inbound bandwidth estimation are enabled. If this member is set to TcpBoolOptDisabled, extended statistics on the TCP connection for inbound bandwidth estimation are disabled. If this member is set to TcpBoolOptUnchanged, extended statistics on the TCP connection for inbound bandwidth estimation are unchanged.
The default state for this member when not set is disabled.
The TCP_ESTATS_BANDWIDTH_RW_v0 structure is used as part of the TCP extended statistics feature available on Windows Vista and later.
The TCP_ESTATS_BANDWIDTH_RW_v0 is defined as version 0 of the structure for read/write configuration information on bandwidth estimation for a TCP connection.
Extended TCP statistics on bandwidth estimation for a TCP connection are enabled and disabled using this structure and the SetPerTcp6ConnectionEStats and SetPerTcpConnectionEStats functions when TcpConnectionEstatsBandwidth is passed in the EstatsType parameter.
The Offset parameter passed to the SetPerTcp6ConnectionEStats and SetPerTcpConnectionEStats functions is currently unused and must be set to 0. Consequently, the TCP_ESTATS_BANDWIDTH_RW_v0 structure pointed to by the Rw parameter when the EstatsType parameter is set to TcpConnectionEstatsBandwidth must have both the EnableCollectionOutbound and EnableCollectionInbound structure members set to the preferred values in a single call to the SetPerTcp6ConnectionEStats and SetPerTcpConnectionEStats functions.
The TCP_ESTATS_BANDWIDTH_RW_v0 structure is retrieved by calls to the GetPerTcp6ConnectionEStats or GetPerTcpConnectionEStats functions when TcpConnectionEstatsBandwidth is passed in the EstatsType parameter.
