Upcoming routing working group chair selection
by Paul Hoogsteder 24 Oct '24

24 Oct '24

Dear Routing working group, As agreed during the RIPE88 Meeting I will step down as co-chair and were going to try to find a suitable new co-chair to join Ben and Ignas. If you are interested, know how RIPE working groups and the community operates or are willing to learn, think you have suitable knowledge about routing, routing security and other interconnection related subjects we ask you to contact routing-wg-chairs(a)ripe.net - NOT this mailing list. After two weeks from now well publish the list of candidates (if any) and issue a call for discussion. Candidates who do announce their interest on this mailinglist or somewhere else in public before the list is announced will not be considered. The actual chair selection will be done during RIPE89 in Prague, both in-room and online using a MeetEcho poll or a similar method. Kind regards, Paul Hoogsteder On behalf of the Routing WG chairs

Moin, I have been working on a document listing terms & abbreviations used in the context of BGP/Global Routing Operations (leftovers from the cut- down of the attempts to update documents in BCP194): https://datatracker.ietf.org/doc/draft-fiebig-grow-routing-ops-terms/02/ I just setup a web-form to collect further terms & abbreviations people would like to also see in the document; If you have a minute, it would be appreciated if you could scroll the document and drop a few lines on what you would like to see added. https://files.measurement.network/apps/forms/s/CMXjrtCPD8QyG6CAWmSLmg4y (In case anyone is concerned: Responses will only be used to update the I-D, and not for any form of research. ;-)) With best regards, Tobias P.S.: No, I will not open the box of defining what a Tier-1 is; That definition can stay in RFC7454, and I believe it is better not to touch that topic. ;-) -- Dr.-Ing.

RPKI: Deployed is better than perfect
by Haya Shulman 25 Sep '24

25 Sep '24

Dear Routing working group, We wrote a paper on RPKI, in which we discuss gaps around RPKI maturity and consider the challenges that need to be addressed to improve the stability and resilience of RPKI and facilitate wider adoption. We are also working on exploring these hurdles and challenges that we listed; we can provide more information to the interested parties separately. The paper is currently a preprint on Arxiv. We would appreciate feedback from a broader group. You can access the research here: https://arxiv.org/pdf/2409.14518 Thanks for your comments in advance. Best, Haya Schulmann -- Prof. Dr. Haya Schulmann Goethe-Universität Frankfurt am Main, FB12/Institut für Informatik Nationales Forschungszentrum für angewandte Cybersicherheit ATHENE

Qualitative Study: “Routing Realities: Assessing the practicality of academic BGP security solutions in network operations”
by Aleeza Suhel Inamdar 13 Sep '24

13 Sep '24

Hello! My name is Aleeza, and I am a student pursuing my Master's thesis at the Max-Planck-Institute for Informatics. I am writing to cordially invite you to participate in an asynchronous online focus group study as part of our research project titled “Routing Realities: Assessing the practicality of academic BGP security solutions in network operations”. Study Overview: This study, conducted by our research team, including myself, Mannat Kaur, and Tobias Fiebig, aims to explore the practicality of academic solutions, with a particular focus on BGP security. Your insights as a network operator will be invaluable in helping us understand the challenges and identify opportunities for improvement. Focus Group Details: Start Date: Around 3rd week of September Platform: Mattermost Total Runtime: 4 - (max) 6 weeks Total Questions: 6 Format: 1 week(maximum)/question Your Participation: As a participant, you will be asked to share your experiences, challenges, perspectives on the practical implementation of BGP security solutions proposed by academic research in real-world network environments, and engage in online group discussions with other network operators. The focus group discussions are asynchronous, and we encourage you to contribute your insights at a pace that suits your schedule. You can engage in the discussions all at once or spread your contributions across multiple days, depending on what is most convenient for you. If you have any questions or need additional information, please feel free to contact us. Registration: https://nextcloud.mpi-inf.mpg.de/index.php/apps/forms/s/WHnXHBDRgo3srisj5w3… I look forward to your participation in this study. Contact: asuhelin(a)mpi-inf.mpg.de, mkaur(a)mpi-inf.mpg.de, tfiebig(a)mpi-inf.mpg.de Thank you!
