RM_SENDER_STATS structure
The RM_SENDER_STATS structure provides statistical information for a Reliable Multicast sender session. This structure is used with the RM_SENDER_STATISTICS socket option.
Syntax
typedef struct _RM_SENDER_STATS { ULONGULONG DataBytesSent; ULONGULONG TotalBytesSent; ULONGULONG NaksReceived; ULONGULONG NaksReceivedTooLate; ULONGULONG NumOutstandingNaks; ULONGULONG NumNaksAfterRData; ULONGULONG RepairPacketsSent; ULONGULONG BufferSpaceAvailable; ULONGULONG TrailingEdgeSeqId; ULONGULONG LeadingEdgeSeqId; ULONGULONG RateKBitsPerSecOverall; ULONGULONG RateKBitsPerSecLast; ULONGULONG TotalODataPacketsSent; } RM_SENDER_STATS;
Members

Total bytes sent, consisting of source path message (SPM), original data (ODATA) and repair data (RDATA) sequences.
- NaksReceived
-
Type: ULONGULONG
-
Number of NAKs received.
- NaksReceivedTooLate
-
Type: ULONGULONG
-
Number of NAKs received after the send window advanced beyond the NAK'ed sequence.
- NumOutstandingNaks
-
Type: ULONGULONG
-
Number of NAKs for which responses have not been sent.
- NumNaksAfterRData
-
Type: ULONGULONG
-
Number of NAKs after repair data (RDATA) sequences were sent for which responses have not been sent.
