Ralith commented on this pull request. > -When there is no data to send, the sender SHOULD send a PING or other -ack-eliciting frame in a single packet, re-arming the PTO timer. +It is possible the sender has no new or previously-sent data to send. +As an example, consider the following sequence of events: new application data +is sent in a STREAM frame, deemed lost, then retransmitted in a new packet, +and then the original transmission is acknowledged. When there is no data to +send, the sender SHOULD send a PING or other ack-eliciting frame in a single +packet, re-arming the PTO timer. In this case, the second packet is ack-eliciting and has not been acknowledged, eventually leading to a probe timeout. However, there is no unsent or sent-but-unacknowledged ack-eliciting data available to send, so a `PING` is fabricated instead. Perhaps "there is new or previously sent data" should be more specific? -- You are receiving this because you are subscribed to this thread.
