by Stephen Strowes 16 Nov '23

16 Nov '23

Hi, There is an open request on the IRTF's PEARG list, seeking feedback on a draft document, "Guidelines for Performing Safe Measurement on the Internet". The MAT WG has expertise and probably feedback to share. The request with appropriate pointers is here: https://mailarchive.ietf.org/arch/msg/pearg/-qGRRbBAZ2YAytwt4lpxVcQ7OZE/ Feedback on the draft is welcome either on their RG discuss list, or by filing issues directly against the git repo.

Unauthenticated user access to RIPE Atlas
by Ben Cartwright-Cox 03 Nov '23

03 Nov '23

Hello everybody! I was wondering around what are the rules and views on “open user access” to RIPE Atlas ( as in non-authenticated users being able to make RIPE atlas measurements) I ask because as of this morning I noticed that hurricane electric’s bgp.he.net tool is now allowing users to make right atlas measurements without any authentication to RIPE Atlas, this was surprising to me as when I asked a NCC staff member at the last meeting in Berlin about doing something similar to this I was explicitly told that this would not be desired. I cannot remember who told me this ( and I don't have an easy way of finding out again ) but assuming this is allowed I will happily copy this for bgp.tools But I'd like to check with Atlas people before doing such a thing.

new discussion list for discussing network neutrality/title ii issues rationally
by Dave Taht 11 Oct '23

11 Oct '23

With the return of the NN discussion and regulation in the USA as of Oct 19th... https://www.fcc.gov/document/fcc-chairwoman-rosenworcels-net-neutrality-rem… and especially with my lack of knowledge and understanding of pending EU regulation, I decided to start a good ole fashioned mailing list to try and sort it all out, which is up to nearly 200 members now. Sign up here: https://lists.bufferbloat.net/listinfo/nnagain I am especially interested in finding new blood of all sorts (engineers, lawyers, scientists, foss folk, and infrastructure folk) willing to discuss possible brighter futures for the internet (with us old farts via this archaic method. I considered trying mastodon but it was too complicated). New metrics for videoconferencing, as well as lower layer metrics like MTTR an MTBF are on my mind, as is finding ways to improve QoE for everyone, and de-crapification of the upper layers of the stack, as well as of the gear we buy. There is a separate NPRM going on for a new FCC CyberSecurity label, which I would like to see more teeth pushed into, honestly. My hope is, one day, we can provide good feedback into various overwhelmed government processes, as we did here, 7+ years ago. http://www.taht.net/~d/fcc_saner_software_practices.pdf PS - is anyone here participating in the renewed cybergeography project? -- Oct 30: https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html Dave Täht CSO, LibreQos

Dear MAT friends, During LACNIC 40 (Fortaleza, Brazil) [1], there will be a session of the Internet Measurements Working Group (IMWG) on Friday 6 October 2023. The IMWG is a new working group with similar goals of MAT but focuses on creating bridges among academia, researchers, and network operators in the LACNIC region. The mailing list of the IMWG is imwg(a)listas.nog.lat Since this year the LACNIC and RIPE events will be more than a month apart, I'm asking here help in creating the agenda for IMWG. The IMWG is looking for presentations on Internet measurements, network data collection, data analysis and tools. Please, submit your presentation proposal by September 22 by sending an email at imwg-owner(a)listas.nog.lat We prefer talks of 15min. Include in your email a title, a draft of the presentation, a paragraph describing what you will talk about and why the topic is of interest for the community, and if you are planning to present in person or remotely. Feel free to share this message on other channels. Thanks! Ciao, Massimo [1] https://lacnic40.lacnic.net/

Contribution submission for MAT WG at RIPE86
by Marco Polverini 10 Apr '23

10 Apr '23

Dear Nina, Massimo and Stephen My name is Marco Polverini, an assistant professor at Sapienza University of Rome. I would like to submit the following proposal to be presented at the next MAT WG. This work has been accepted to be presented at the IEEE NOMS 23 ( https://noms2023.ieee-noms.org/). Attached to this email you can find the original paper (in case you need further details about the topic of the presentation I would like to do). Thanks Marco *Title:* A Digital Twin based Framework to Enable "What-If" Analysis in BGP Optimization *Outline of the speech:* - introduction and motivation: in this talk we aim to introduce a framework for the creation of Digital Twins of Autonomous Systems in order to enable the execution of "what if" analysis in the context of inter domain routing optimization - background on digital twins: this section is to introduce the basic terminology and concepts on Digital Twins - presentation of the proposed framework: in this section we provide an overview of the architecture of the proposed framework and detail the responsibilities of each functional block - proof of concept: a simple proof of concept is presented, with the aim of showing the effectiveness of the proposal - conclusion and future work *Abstract:* Nowadays, inter domain routing optimization is performed based on the so called "Tweak and Pray" approach, which consists in performing changes in the configuration of the BGP protocol without knowing in advance the consequences of such a modification. This is due to the lack of cooperation among Network Operators in the configuration of the BGP to optimize the inter domain routing. Inefficiency in the resource usage, network anomalies and outages are common consequences of wrong configuration changes performed by Network Operators in an attempt to improve the performance of their infrastructures. In this paper we propose a novel framework based on the Digital Twin technology to enable the execution of "what-if" analysis in the context of Traffic Engineering performed by tuning BGP parameters. Such a paradigm shift will allow Network Operators to be aware of the effects of BGP configuration changes before their actual execution. A proof of concept related to the balancing of inbound traffic in an Autonomous System network, based on the use of the AS Path Prepending technique, is realized to validate the feasibility of the proposed approach.

I have been asking to several ncc contacts and there was no suitable solution for this at the moment. Asking researchers/developers to create their own LIRs so that resources can be transferred is not a practical solution, but I'm not sure you are referring to this.

Assignments done by LIRs of their own resources do not require approval, while they would satisfy the research use case (in summary: using prefixes from the ncc stash is not needed in all cases). Thanks for your answers. Ciao, Massimo
