Non-ack-eliciting packets are eventually acknowledged when the endpoint sends an ACK frame in response to other events. -In order to assist loss detection at the sender, an endpoint SHOULD send an ACK -frame immediately on receiving an ack-eliciting packet that is out of order. The -endpoint SHOULD NOT continue sending ACK frames immediately unless more -ack-eliciting packets are received out of order.

A receiver does not know whether there are _missing packets_. We should simply state that there is a gap in the packet numbers. -- You are receiving this because you are subscribed to this thread.
