New on RIPE Labs: Internet Clouds are (also) Unpredictable
by Mirjam Kuehne 01 Mar '22

01 Mar '22

Dear colleagues, How does the largest cloud provider worldwide perform Traffic-Engineering? What are the implications for the geo-distributed applications running in the cloud? Marco Chiesa and his colleagues explored these and more questions through a comprehensive set of measurements across the Amazon Web Services (AWS) cloud network. Please find the results on RIPE Labs: https://labs.ripe.net/Members/marco_chiesa/internet-clouds-are-also-unpredi… Marco will be a RACI fellow at RIPE 79 and will present his research there. Kind regards, Mirjam Kühne RIPE NCC

by Petrit Hasani 04 Nov '19

04 Nov '19

Dear colleagues, A new RIPE Policy proposal, 2019-08, "RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space" is now available for discussion. This proposal aims to instructs the RIPE NCC to create ROAs with origin AS0 for all unallocated and unassigned address space under its control. You can find the full proposal at: https://www.ripe.net/participate/policies/proposals/2019-08 As per the RIPE Policy Development Process (PDP), the purpose of this four week Discussion Phase is to discuss the proposal and provide feedback to the proposer. At the end of the Discussion Phase, the proposer, with the agreement of the WG Chairs, will decide how to proceed with the proposal. We encourage you to review this proposal and send your comments to <routing-wg(a)ripe.net> before 29 November 2019. Kind regards, -- Petrit Hasani Policy Officer RIPE NCC

Minutes from RIPE 78
by Rob Evans 17 Oct '19

17 Oct '19

All, I don't believe a pointer has been sent out to the minutes from the meeting at RIPE 78. The draft minutes are, with thanks to the RIPE NCC, at the following URL. <https://www.ripe.net/participate/ripe/wg/routing/minutes/routing-working-gr…> To give you the opportunity to review them, I'll not call for them to be declared final at the meeting this morning. Instead, please send comments on them by the end of the month, and if there are no comments, the chairs that are selected this morning will declare them final on October 31st. Cheers, Rob

Agenda routing-wg RIPE-79
by Iljitsch van Beijnum 14 Oct '19

14 Oct '19

Hi all, As far as I can tell there is no agenda for the routing WG on Thursday. There are two topics I would love to see discussed: 1. AS path lengths: I think we need to come up with a recommendation as a community so both people who like to prepend and people who like to filter very long AS paths know what they should and shouldn't do. Agree? And what should that AS path limit be? (Also see the presentation about long AS paths in the plenary tomorrow, no idea to what degree that will inform the above.) 2. AS path validation. See earlier discussions. Iljitsch

Paolo Moroni sent me and his co-chair the following message during the last RIPE meeting on May 23rd: «After three years of serving as co-chair of the Routing working group, I have decided not to continue with this activity and step down as from now.» As We have not been able to establish contact with Ignas Bagondas for a while, I have appointed two interim chairs Job Snijders and Rob Evans to arrange the WG session at the upcoming RIPE meeting. The wg need to replace Paolo with a new co-chair. If you are interested in serving as co-chair of the routing-wg please send a message to the list with a motivation statement and a short bio, Hans Petter Holen RIPE Chair https://www.ripe.net/participate/ripe/wg/routing/routing-wg-chair-selection… The RIPE Routing Working Group should attempt to maintain two Chairpersons whenever possible. As a large part of the work of the Chairpersons is in creating an agenda for the Working Group meetings at RIPE meetings, these are generally appointed by consensus of those present at a Working Group meeting. Each of the Chairpersons may periodically offer to stand down to allow new candidates to stand in their place. The Chairperson that wishes to stand down should announce that to the Working Group's mailing list two weeks before the meeting. Nominations for Chairpersons may be accepted up to the day before the Working Group's meeting. -- -- Hans Petter Holen Mobile +47 45 06 60 54 | hph(a)oslo.net | http://hph.oslo.net

2018-06 Last Call (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up)
by Marco Schmidt 07 Oct '19

07 Oct '19

Dear colleagues, Policy proposal 2018-06, "RIPE NCC IRR Database Non-Authoritative Route Object Clean-up", is now in Concluding Phase. The goal of the proposal is to delete an non-authoritative object stored in the RIPE IRR, if it conflicts with an RPKI ROA. The WG co-chair has declared that rough consensus has been reached and the proposal will now move to Last Call. As per the RIPE Policy Development Process (PDP), the purpose of this four week Concluding Phase is to give an opportunity to present well-justified objections for those who missed the previous two phases and wish to oppose the proposal. Any objection must be made before 5 November 2019 and must be supported by an explanation. If no substantive objections are raised by the end of Last Call, the proposal will complete the PDP and will be evaluated by the WG co-chairs for final consensus. You can find the full proposal at: https://www.ripe.net/participate/policies/proposals/2018-06 Please e-mail any final comments about this proposal to <routing-wg(a)ripe.net> before 5 November 2019. Regards, Marco Schmidt Policy Officer RIPE NCC
