L4S Trials (Comcast) & Inter-Domain Marking
by Livingood, Jason 22 Jun '23

22 Jun '23

FYI on two related items of interest to this list. 1 – If you are a Comcast customer, consider volunteering for our upcoming low latency networking trials (using IETF L4S). See my blog post at https://corporate.comcast.com/stories/comcast-kicks-off-industrys-first-low… and signup at https://www.xfinityinsightscommunity.com/register/start/f4f1ea42-247c-44f1-…. 2 – The IETF L4S standard and the upcoming NQB standards – both dual-queue low latency networking – will rely on end-to-end packet marking to signal dual-queue-capable routers to send packets to the low latency queue. Thus, there will be inter-domain marking which will affect many networks’ edge configurations. * In the case of L4S it may be easier, as L4S relies on the ECN header – and most networks probably forward packets without touching this header. The L4S setting here is to set ECT(1) or CE. * In the case of NQB, the marking is expected to use DSCP-45 (once the RFCs are issued, IANA will make the code point assignment). This will be more challenging for those networks that scrub any DSCP marks from packets and over-write with their own. Post-standardization, networks should permit inbound DSCP-45 marks to remain & pass them along down to the user edge (in cases where 45 is used internally, networks may remark internally and then mark back to 45 as it goes to the user LAN). * In both cases – ECN or DSCP – the packets remain at the best effort priority level. * For slightly more detail see https://github.com/jlivingood/IETF-L4S-Deployment/blob/main/Network-Config-… Thanks!

New addresses for b.root-servers.net
by Robert Story 21 Jun '23

21 Jun '23

USC/ISI is renumbering both its IPv4 and IPv6 addresses for b.root-servers.net on 2023-11-27. Our new IPv4 address will be 170.247.170.2 and our new IPv6 address will be 2801:1b8:10::b. USC/ISI will continue to support root service over our current IPv4 and IPv6 addresses for at least one year (until 2024-11-27) in order to provide a stable transition period while new root hints files are distributed in software and operating system packages. We are renumbering to increase the resilience of the Root Servers System by further diversifying the number of Regional Internet Registries (RIRs) that have allocated IP addresses to Root Server Operators. Our addresses will be the first in the Root Server System to have been allocated by LACNIC and our routes will be verifiable through LACNIC’s Resource Public Key Infrastructure (RPKI) Trust Anchor Location (TAL). We thank LACNIC for helping make this renumbering possible, and ARIN for supporting our prior addressing assignments. The LACNIC announcement, with English, Spanish and Portuguese translations, can be found on their website here: https://www.lacnic.net/6868/1/lacnic/lacnic-asigna-recursos-de-numeracion-a… Please direct any comments or questions to b-poc <at> isi.edu. Regards, Robert P.S.

FCC Chair Rosenworcel Proposes to Investigate Impact of Data Caps
by Sean Donelan 20 Jun '23

20 Jun '23

While a lot of ISPs gave up on data caps, the language is still lurking in many Terms Of Service. https://www.fcc.gov/document/chair-rosenworcel-proposes-investigate-impact-… proposed Notice of Inquiry to learn more about how broadband providers use data caps on consumer plans. Data caps, or usage limits, are a common practice where an internet service provider (ISP) restricts how much bandwidth or data a consumer uses, though many broadband ISPs temporarily or permanently refrained from enforcing or imposing data caps in response to the COVID-19 pandemic. In particular, the agency would like to better understand the current state of data caps, their impact on consumers, and whether the Commission should consider taking action to ensure that data caps do not cause harm to competition or consumers’ ability to access broadband Internet services.

That's been the general theme with operators who are traditionally Layer 1 or Layer 2 service providers, looking to dabble into packet switching. It often makes sense for them to speak to their Transport vendor, as their gear is already an installed base. Two or so years later, those operators will be ripping those Transport boxes out and replacing them with more traditional packet switching gear, as you did as well. Transport vendors continue to push their boxes as being MPLS-capable routers. It tends to be a "tick the box that we had that conversation this new year, make it last at least 3 seconds, and then carry on with real talk" situation :-). Mark.

Association with a General Member organization is not required. Nominees will be assessed based on the direction received from the Board and AC, as outlined in the following guidance letters: * Board Guidance Letter to the Nomination Committee https://www.arin.net/vault/participate/elections/board_nomcom_guidance2023.… * AC Guidance Letter to the Nomination Committee https://www.arin.net/vault/participate/elections/ac_nomcom_guidance2023.pdf To view the requirements, expected qualifications, and/or responsibilities for these elected positions, please visit: * Board of Trustees: https://www.arin.net/about/welcome/board/requirements/ * Advisory Council: https://www.arin.net/about/welcome/ac/requirements/ All nominees must confirm that they do not violate the Nomination and Appointment Conflict of Interest Requirements found at: https://www.arin.net/participate/oversight/elections/processes/conflicts/ Completed nominee questionnaires must be submitted before the Call for Nominations closes at 7:00 PM ET on Friday, 30 June. In addition, Board nominees must digitally sign a release form allowing an independent third party to conduct a background check. Nominees who do not complete the required steps will not be eligible for consideration. Nomination Process and Election Slate Development For detailed information on the ARIN Election nomination process, please visit: https://www.arin.net/participate/oversight/elections/processes/#iv-nominati… For 2023, the process for evaluating nominees is notably different. The Nomination Committee (NomCom) is responsible for helping in the recruitment of individuals to self-nominate for the election. All nominees must self-nominate and complete all nomination materials to be considered for the Initial Candidate Slate. Nominees will be evaluated and assessed by an independent, third-party vendor, and all qualified nominees will appear on the ballot. The evaluation of qualifications will be based on the nominee questionnaire responses, background checks (Board only) and interviews, and the guidance letters received from the Board and AC. The Candidate Slate will include at least five candidates for the Board and at least seven candidates for the AC. The open seats up for election will include three three-year term seats and one one-year term seat for the Board; for the AC, there will be five three-year term seats and one one-year term seat. Seats with partial terms are filled by the nonelected candidate who possesses the highest number of votes cast for the position and who is willing to serve. Additional information about the Nomination Process: * NomCom members: https://www.arin.net/about/welcome/board/committees/#nomination-committee-n… * NomCom Charter: https://www.arin.net/about/welcome/board/committees/charters/#nomcom Initial Slate With the completion of its qualification classification process, the NomCom will provide an Initial Slate of Candidates for the Board and AC based on the assessments and information provided by the third-party vendor.
