APRICOT 2026: Call for Volunteers (Programme Committee)
by Mark Tinka 31 Aug '25

31 Aug '25

Hello all. The APRICOT 2026 Organising Committee would like to welcome everyone to join us in Jakarta, Indonesia, from 5th - 12th February 2026. The APRICOT 2026 PC (Programme Committee) is responsible for the solicitation and selection of suitable presentations and tutorial content for the APRICOT 2026 conference (https://2026.apricot.net/) We are now seeking VOLUNTEERS from the community to join the APRICOT 2026 PC to assist with the development of the programme for APRICOT 2026. Eligible PC candidates must have attended recent APRICOT events, be active members of their local NOG (Network Operators Group) in the Asia Pacific region, have broad technical knowledge of Internet operations, and have good familiarity with the format of APRICOT. Having constructive opinions and ideas about how the programme content might be improved is of high value too. PC members are expected to work very actively to solicit content, follow-through with speaker updates and review submissions for technical merit. The PC meets by conference call, weekly in frequency during the three months prior to APRICOT. While participation in the weekly calls is not obligatory, active participation in content reviews is required at all times to help the PC reach consensus. PC members who are unable to fully participate in the programme development will be excused from the PC. If you are interested in joining the PC and meet the above eligibility criteria, please send a brief note to "pc-chairs at apricot.net". The note must include affiliation (if any) and a brief description about why you would make a good addition to the PC. The PC Chairs will accept nominations received by 17:00hrs UTC+8 on Sunday 7th September 2025, and will announce the new PC shortly thereafter. Many thanks! Mark Tinka, Achie Atienza & Mark Duffell APRICOT 2026 Programme Committee Chairs

Policy Proposal 2025-02 Review Phase (Revocation of Persistently Non-functional Delegated RPKI CAs)
by Karen Hung 25 Aug '25

25 Aug '25

Dear colleagues, Policy proposal 2025-02, "Revocation of Persistently Non-functional Delegated RPKI CAs", is now in the Review Phase. The RIPE NCC has prepared an impact analysis on this proposal to support the community’s discussion. You can find the proposal and impact analysis at: https://www.ripe.net/community/policies/proposals/2025-02/ https://www.ripe.net/community/policies/proposals/2025-02#impact-analysis And the draft document at: https://www.ripe.net/community/policies/proposals/2025-02/draft/ As per the RIPE Policy Development Process (PDP), the purpose of this four-week Review Phase is to continue the discussion of the proposal taking the impact analysis into consideration, and to review the full draft RIPE Policy Document. At the end of the Review Phase, the Working Group (WG) Chairs will determine whether the WG has reached rough consensus. It is therefore important to provide your opinion, even if it is simply a restatement of your input from the previous phase. We encourage you to read the proposal, impact analysis and draft document and to send any comments to routing-wg(a)ripe.net <mailto:routing-wg@ripe.net> before 5 September 2025. Kind regards, Karen Hung On behalf of Policy Officer RIPE NCC

Re: Source Address Validation (SAV) Deployment and Operational Practices
by Libin Liu 08 Aug '25

08 Aug '25

Dear Nicholas and All, Thank you, Nicholas, for sharing this information and your work. I think this is an interesting topic, which is discussed and studied in the IETF SAVNET WG. I would also like to take this opportunity to introduce our SAV emulation project, SAV Open Playground (SAVOP). SAVOP is an open platform designed to implement and evaluate various SAV mechanisms, including uRPFs, BAR-SAV, and other emerging approaches discussed in SAVNET. We presented it and corresponding results on top of it at multiple SAVNET WG meetings and IETF hackathons since IETF 116, and we open-sourced its codes, which is available at https://github.com/SAV-Open-Playground. We also published a short paper at IRTF ANRW 2024 to introduce SAVOP. You can access it by https://dl.acm.org/doi/10.1145/3673422.3674888. I also encourage you to review the survey questions and share your responses, and I am interested in your answers and how you think about it. Thanks Nicholas and all. Please feel free to reach out with any questions or ideas. Best, Libin From: Scaglione, Nicholas <nicholas.scaglione(a)uconn.edu> Sent: Thursday, August 7, 2025 5:02 AM To: routing-wg(a)ripe.net Subject: [routing-wg] Source Address Validation (SAV) Deployment and Operational Practices Friends: uRPF and similar SAV techniques have been around for long, with new variants recently/being standardized by the IETF (EFP-uRPF, BAR-SAV). We have done simulations to evaluate the impacts of these variants. To improve our research, we set up a short, quick survey for network managers and administrators of ASNs. In this study, we want to understand the deployment challenges, operational considerations, adoption trends and operator concerns in this area. It would be amazing if you could respond to the survey, available in: https://forms.gle/3rRtCTa2xk217tyd6 We really appreciate your help. The form also contains an option to leave your email for us to send you our research results (paper, simulations, survey).
