Gorry and Arjuna - This looks fine to me. One sentence needs to be corrected: Section 2.4 says the following: "Reception of a Quick-Start Response packet results in the sender entering the Quick-Start Mode." I think this needs to be rephrased. Later text gives conditions when the reception of a Quick-Start Response packet doesn't result in the sender entering the Quick-Start Mode. E.g., when "the approved Quick-Start rate is less than current sending rate". The rest of my feedback below is all nits and typos and such. - Sally http://www.icir.org/floyd/ NIts and typos: Introduction, next to last paragraph: "Rate-based protocols (e.g. TFRC [RFC5348], CCID-3 [RFC4342]) have a different feedback mechanism compared to TCP, where feedback may be sent less frequently (e.g. once per RTT)." -> "Rate-based protocols (e.g. TFRC [RFC5348], CCID-3 [RFC4342]) have a different feedback mechanism than that of TCP. With rate-based protocols, feedback may be sent less frequently (e.g. once per RTT)." Introduction: "implement different mechanism" -> "implement a different mechanism" Section 2.3: Could you swap the last two paragraphs? Secton 2.3, next to last paragraph: "Request, therefore" -> "Request therefore" Section 2.5, first paragraph: "period, during" -> "period during" Section 2.5, second paragraph: "when sender" -> "when the sender" Section 2.5, Figure 2: It might be more clear to have this for Quick-Start Mode: +----------------------------------------------+ | Quick-Start Packets --> | | <-- Feedback A from Receiver | | (first feedback of a QS Packet) | | Quick-Start Packets --> | | <-- Feedback B from Receiver | | (feedback of all QS Packets) | | Receipt of Feedback A +----------------------------------------------+ And then the Quick-Start Validation Phase could end with "Receipt of Feedback B". Section 2.5, last paragraph: "congestion, stops" -> "congestion stops" Section 2.7, next to last paragraph: "effects multiple connections" -> "affects multiple connections" The sections go 2.8, then 2.8, then 2.10. Section 2.10, last paragraph: "connnection, and" -> "connnection and" Section 3.2: "CCID-3, leads" -> "CCID-3 leads" Section 3.2.4, third paragraph: "congestion, stops" -> "congestion stops" Section 3.3.1: "packet per second" -> "packets per second" Section 4.2, second paragraph: "link or network-layer paths" -> "links or network-layer paths"
