Mirja Kühlewind has entered the following ballot position for draft-ietf-tsvwg-rfc4960-errata-06: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-rfc4960-errata/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- 1) sec 3.27.2: " o When the endpoint does not transmit data on a given transport address, the cwnd of the transport address SHOULD be adjusted to max(cwnd/2, 4*MTU) per RTO. At the first cwnd adjustment, the ssthresh of the transport address SHOULD be adjusted to the cwnd." This part is still unclear to me. What does adjust "per RTO mean"? I guess it is sufficient to adjust it once after the first RTO without data, no? Also I assume ssthresh is set after the cwnd adjustment? 2) sec 3.28.2 "An SCTP receiver MUST NOT generate more than one SACK for every incoming packet, other than to update the offered window as the receiving application consumes new data. When the window opens up, an SCTP receiver SHOULD send additional SACK chunks to update the window even if no new data is received. The receiver MUST avoid sending large bursts of window updates." This is also not super well specified now. What is a large burst? I would rather like to see something like "The receiver MUST not send more then one window update per RTT." 3) 3.31. Would it make sense to then use a different variable, e.g. cwnd_temp or max_send_limit, and not cwnd...? 4) Text changes in sec 3.35.2. are kind of unclear. I assume the new text should be added at the end of the old text sections...?
