Packet Reception in ACK Frequency Spec example doesnt specify packets received in batch

[gaurav2699]

The examples provided explains how each packet received would elicit an acknowledgment. However, it does not explicitly mention that packets are not received in batches.
To avoid any potential confusion, I think its worth to add clarification in the specification to state that packets are not received in batches. This would help ensure that the behavior of acknowledgment frequency is clearly understood.

I'm not sure if I understand this comment. It really doesn't matter if packets are received in batches or not, because at the end each packet and more importantly each ACK frame contained in a packets needs to be processed. Or can you make a proposal where exactly you would like to see which clarification?

Also there is a comment on batch processing (as packets could be received in batches) in section 6.5:

To avoid sending multiple acknowledgments in rapid succession, an
endpoint can process all packets in a batch before determining
whether to send an ACK frame in response, as stated in Section 13.2.2
of [QUIC-TRANSPORT].

@mirjak the issue is that the example assumes you send ACKs immediately after processing individual packets; but if the packets were processed in batch, which as you point out is suggested, the ACKs you send out would actually be different. Overall, it effects the logic of when and what to send, depending on batching.

[mirjak]

The example assume that the ACK frames are process in the order as given in the example, basically one by one. You mean we should say that explicitly?

[nibanks]

Yes, exactly.
