Thank you for the explanation, @kazuho. I think I now understood the problem. > Mathematically, this might be unbounded, but it's more likely that in practice the limit is 2*active_connection_id_limit as it would be unlikely that unacknowledged RETIRE_CONNECTION_ID frames would remain so once more NEW_CONNECTION_ID frames start arriving. More so as the issuer of those NEW_CONNECTION_ID frames has to have received the RETIRE_CONNECTION_ID frames. This would require endpoints to make assumptions about how the peer handles the `active_connection_id_limit` and how it issues new CIDs. This can get complicated really quickly and leave the connection in an unrecoverable state (or at the least a state with less CIDs than it should have). Introducing a new frame, as @kazuho suggested, seems a lot cleaner to me. -- You are receiving this because you are subscribed to this thread.
