RM_RECEIVER_STATS structure (wsrm.h)

The RM_RECEIVER_STATS structure provides statistical information for a Reliable Multicast receiver session. This structure is used with the RM_RECEIVER_STATISTICS socket option.

Members

NumODataPacketsReceived

Type: ULONGULONG

The number of original data (ODATA) sequences received.

NumRDataPacketsReceived

Type: ULONGULONG

The number of repair data (RDATA) sequences received.

NumDuplicateDataPackets

Type: ULONGULONG

The number of duplicate sequences received.

DataBytesReceived

Type: ULONGULONG

The number of data bytes received.

TotalBytesReceived

Type: ULONGULONG

The total bytes received, consisting of source path message (SPM), original data (ODATA) and repair data (RDATA) sequences.

RateKBitsPerSecOverall

Type: ULONGULONG

An internally calculated receive rate from the beginning of the session, in kilobits per second.

RateKBitsPerSecLast

Type: ULONGULONG

The receive rate for the period specified by INTERNAL_RATE_CALCULATION_FREQUENCY.

TrailingEdgeSeqId

Type: ULONGULONG

The oldest sequence identifier in the receive window.

LeadingEdgeSeqId

Type: ULONGULONG

The newest sequence identifier in the receive window.

AverageSequencesInWindow

Type: ULONGULONG

The average number of sequences in the receive window.

MinSequencesInWindow

Type: ULONGULONG

The minimum number of sequences in the receive window.

MaxSequencesInWindow

Type: ULONGULONG

The maximum number of sequences in the receive window.

FirstNakSequenceNumber

Type: ULONGULONG

NumPendingNaks

Type: ULONGULONG

The number of sequences awaiting a NAK confirmation.

NumOutstandingNaks

Type: ULONGULONG

The number of sequences awaiting repair data (RDATA).

NumDataPacketsBuffered

Type: ULONGULONG

The number of packets currently buffered.

TotalSelectiveNaksSent
