TCP_ESTATS_BANDWIDTH_ROD_v0 structure (tcpestats.h)
The TCP_ESTATS_BANDWIDTH_ROD_v0 structure contains read-only dynamic information for extended TCP statistics on bandwidth estimation for a TCP connection.
Syntax
typedef struct _TCP_ESTATS_BANDWIDTH_ROD_v0 {
ULONG64 OutboundBandwidth;
ULONG64 InboundBandwidth;
ULONG64 OutboundInstability;
ULONG64 InboundInstability;
BOOLEAN OutboundBandwidthPeaked;
BOOLEAN InboundBandwidthPeaked;
} TCP_ESTATS_BANDWIDTH_ROD_v0, *PTCP_ESTATS_BANDWIDTH_ROD_v0;
Members
OutboundBandwidth
Type: ULONG64
The computed outbound bandwidth estimate, in bits per second, for the network path for the TCP connection.
InboundBandwidth
Type: ULONG64
The computed inbound bandwidth estimate, in bits per second, for the network path for the TCP connection.
OutboundInstability
Type: ULONG64
A measure, in bits per second, of the instability of the outbound bandwidth estimate for the network path for the TCP connection.
InboundInstability
Type: ULONG64
A measure, in bits per second, of the instability of the inbound bandwidth estimate for the network path for the TCP connection.
OutboundBandwidthPeaked
Type: BOOLEAN
A boolean value that indicates if the computed outbound bandwidth estimate for the network path for the TCP connection has reached its peak value.
InboundBandwidthPeaked
Type: BOOLEAN
A boolean value that indicates if the computed inbound bandwidth estimate for the network path for the TCP connection has reached its peak value.
Remarks
The TCP_ESTATS_BANDWIDTH_ROD_v0 structure is used as part of the TCP extended statistics feature available on Windows Vista and later.
The TCP_ESTATS_BANDWIDTH_ROD_v0 is defined as version 0 of the structure for read-only dynamic information for extended TCP statistics on bandwidth estimation for a TCP connection. This information is available after the connection has been established.
The TCP_ESTATS_BANDWIDTH_ROD_v0 structure is retrieved by calls to the GetPerTcp6ConnectionEStats or GetPerTcpConnectionEStats functions when TcpConnectionEstatsBandwidth is passed in the EstatsType parameter. Extended TCP statistics need to be enabled to retrieve this structure.
The members of this structure are not defined in the IETF RFC on the TCP Extended Statistics MIB. For more information on this RFC, see http://www.ietf.org/rfc/rfc4898.txt.
