Members

dwSize

Size of the structure.

dwRoundTripLatencyMS

Approximate time, in milliseconds (ms), it takes a packet to reach the remote computer and be returned to the local computer. This number will change throughout the session as link conditions change.

dwThroughputBPS

Approximate throughput, in bytes per second (Bps), for the link. This number will change throughout the session as link conditions change. This value is approximate, and you may want to calculate your own value for greater accuracy.

dwPeakThroughputBPS

Peak throughput, in bytes per second (Bps) for the link. This number will change throughout the session as link conditions change. This value is approximate, and you may want to calculate your own value for greater accuracy.

dwBytesSentGuaranteed

Amount, in bytes, of guaranteed messages that have been sent.

dwPacketsSentGuaranteed

Number of packets of guaranteed messages that have been sent.

dwBytesSentNonGuaranteed

Amount, in bytes, of nonguaranteed messages that have been sent.

dwPacketsSentNonGuaranteed

Number of packets of nonguaranteed messages that have been sent.

dwBytesRetried

Amount, in bytes, of messages that have been retried.

dwPacketsRetried

Amount of packets that have been retried.

dwBytesDropped

Amount, in bytes, of messages that have been dropped.

dwPacketsDropped

Number of packets that have been dropped.

dwMessagesTransmittedHighPriority

Number of high-priority messages that have been transmitted.

dwMessagesTimedOutHighPriority

Number of high-priority messages that have timed out.

dwMessagesTransmittedNormalPriority

Number of normal-priority messages that have been transmitted.

dwMessagesTimedOutNormalPriority

Number of normal-priority messages that have timed out.

dwMessagesTransmittedLowPriority

Number of low-priority messages that have been transmitted.

dwMessagesTimedOutLowPriority

Number of low priority messages that have timed out.

dwBytesReceivedGuaranteed

Amount, in bytes, of guaranteed messages that have been received.

dwPacketsReceivedGuaranteed

Number of packets of guaranteed messages that have been received.

dwBytesReceivedNonGuaranteed

Amount, in bytes, of nonguaranteed messages that have been received.

dwPacketsReceivedNonGuaranteed

Number of packets of nonguaranteed messages that have been received.

dwMessagesReceived

Number of messages that have been received.
