(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-le-phb/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- I believe that this should be trivial DISCUSS to address, but I thought it important enough to warrant it. I'm OK with basically whatever you answer, I just wanted to make sure this had been seen and considered. "An LE PHB SHOULD NOT be used for a customer’s "normal Internet" traffic nor should packets be "downgraded" to the LE PHB instead of being dropped, particularly when the packets are unauthorized traffic. " Great, sounds good to me -- but in the USA at least, there is are many cell phone plans which are "unlimited", but after some amount of traffic (e.g 22GB) your connection gets throttled to a lower data rate. Is this traffic still 'a customer's "normal Internet" traffic"? Is it appropriate (whatever that means) to downgrade this traffic to the LE PHB? I understand not wanting to touch this issue with a 10 foot pole (and I don't know what the right answer is!), but you *did* open this can of worms by talking about what classification user traffic should have. Note: I'm happy to clear my DISCUSS no matter what the answer is, I just want to make sure it has been considered / discussed. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Major: "Some network providers keep link utilization below 50% to ensure that all traffic is forwarded without loss after rerouting caused by a link failure (cf.Section 6 of [RFC3439]). LE marked traffic can utilize the normally unused capacity and will be preempted automatically in case of link failure when 100% of the link capacity is required for all other traffic. " Yup - very true. But I think it needs to be mentioned that the provider will need to upgrade their monitoring / management system so that they can see the traffic lass. If they monitoring circuit utilization using e.g interface counters (and not by traffic class), a link may have 1% "real" traffic and 90% LE traffic, and it will look like it it 91% "full". I don't have any suggested text to address this (and this is just a comment, so "well, duh, they should know that anyway!" is a fine answer.) Nits: "A main problem is that multicast" -- I'm not sure you can say "A main" - main implies singular.; I'd suggest "The main" or "A major". "However,using the Lower Effort PHB for multicast requires to pay special" -- "requires paying"...
