Number of NCFs received with reason code "rx_delay" (LBT-RM, LBT-RU)

C# |
public long ncfsRetransmissionDelay()

Number of NCFs that have been received with the reason
code set to "rx_delay".

When a source transport's retransmit rate limiter prevents it from
immediately retransmitting any more lost datagrams, it responds to a NAK by
sending an "NCF rx_delay", then queues the retransmission for a later send.
The receiver transport should wait for the retransmission and not immediately
send another NAK. If this count is high, one or more crybaby receiver
transports may be clogging the source transport's retransmit queue.
This method returns a value from the first
set of statistics encapsulated within this object
and would normally be used when the object has been
created using a specific source to instantiate the class.
