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

Update on improved rsync repository publication
by Ties de Kock 01 Jun '21

01 Jun '21

Dear colleagues, Over the last weeks, as mentioned in a previous email [0], we have been exploring two approaches to improve our rsync publication process in parallel. The first approach (“batched publication”) changes the RPKI system to atomically publish the complete set of files instead of writing them at multiple places in the code. For rsync, after all files have been written to a new directory, the repository is switched to the new content by atomically updating a symlink. The repository is updated every 15 minutes. We plan to deploy this soon during a scheduled downtime. During this downtime the repositories will be available, but managing a certification authority will not be possible. The second approach uses RRDP as a source of truth and writes the repository to a local disk (instead of to NFS) with krill-sync (which also uses a symlink as the base for the current rsync module). We have an experimental rsync environment based on the second approach available for testing. The environment contains the production RPKI repository. Please note that this environment is experimental and thus is not considered to be a critical service. Do not rely on this service for production networks. We may cause downtime on this service to adjust the configuration. However, when services are available, the content should be valid and contain the same objects as the production RRDP repository. It updates from RRDP every minute. The non-repeatable reads should not occur. rpki2.ripe.net provides all services (rsync repo, HTTPS trust anchor certificate) that rpki.ripe.net provides. The recommended way to test this is by making sure that your traffic that usually goes to rpki.ripe.net arrives at the IPs of rpki2.ripe.net. We will evaluate this environment with multiple relying party instances and a tool that checks for repository divergence over the coming weeks. In parallel, we are finishing the configuration (e.g. metrics and alerting). Please share your feedback with us at rpki(a)ripe.net. We aim to deploy the first approach before the end of the month. Kind regards, Ties de Kock [0] https://www.ripe.net/ripe/mail/archives/routing-wg/2021-April/004314.html

New on RIPE Labs: Future Internet at Terabit Speeds - SCION in P4
by Alun Davies 27 May '21

27 May '21

Dear colleagues, As part of the 2STiC programme, SIDN Labs evaluates and experiments with future Internet architectures. One of these is SCION. In this guest post on RIPE Labs, Joeri de Router and Caspar Schutijser introduce the high-speed SCION router prototype they implemented to find out if a complex protocol such as SCION can run directly on hardware using the flexibility provided by P4. https://labs.ripe.net/author/joeri-de-ruiter/future-internet-at-terabit-spe… Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

New on RIPE Labs: SCION - A Novel Internet Architecture
by Alun Davies 17 May '21

17 May '21

Dear colleagues, At RIPE 81, a group of enthusiastic researchers and practitioners from industry and academia discussed with the RIPE community what role RIRs and LIRs could take on in the SCION next-generation Internet architecture. Ahead of the second SCION BoF taking place today at RIPE 82, David Hausheer looks back at what happened at the last BoF, reports on what has happened since then, and presents what potential RIPE involvement could look like in the future.

Security & Compliance reports for RPKI
by Nathalie Trenaman 10 May '21

10 May '21

Dear colleagues, Security is always high on our list of priorities for RPKI. Every year, we ask an external party to carry out a security audit of our RPKI systems. This is the first year that we are publishing the security report, in an effort to increase transparency and trust in the RPKI system. Please note that the report also listed several recommendations that should be included in a penetration test. These recommendations have been redacted from the original report, as we will include them in the penetration test scheduled for June 2021. Also, some comments about the proprietary software for the Hardware Security Module have been redacted. On https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/security-… you will now find the RFC compliance report written by Radically Open Security in 2020 and our response to their findings. We hope you will find these reports useful, and we look forward to your feedback. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC
