Updated RPKI CPS Document Review
by Tim Bruijnzeels 14 May '24

14 May '24

Dear colleagues, We have published an updated draft of the "RIPE NCC Certification Practice Statement (CPS) for the Resource Public Key Infrastructure (RPKI)" for review: https://www.ripe.net/publications/docs/draft-update-of-the-ripe-ncc-certifi… The CPS provides a detailed outline of the implementation of RPKI by the RIPE NCC, following the template defined in RFC 6484. The current CPS no longer accurately describes this implementation so we have updated it. The most significant changes in the new version are: - Updated description of the offline TA signing process - The maximum latency for CRL publication now matches that of other object types* - We updated roles and job descriptions where applicable - We fixed some minor inaccuracies - We made some small editorial improvements *We changed the value to a maximum eight hour latency between issuance and publication, also used for other types. It is only in the event of multiple failures in our redundant infrastructure that we can expect significant latency. In practice, publication of RPKI data happens well within 10 minutes after issuance. For reference, the current CPS is RIPE Document ripe-751: https://www.ripe.net/publications/docs/ripe-751/. Though the CPS is published as a RIPE Document, it is not subject to the RIPE Policy Development Process (PDP). The CPS documents the RIPE NCC's implementation of RPKI and is provided for transparency. We invite everyone to review the updated draft and let us know on the mailing list if they have any comments, questions or concerns. If no significant issues are raised then we plan to publish the draft CPS as a RIPE Document on 30 April 2024. Kind regards, Tim Bruijnzeels Principal Engineer RPKI RIPE NCC

FYI: Green Routing protocols
by Vesna Manojlovic 03 Apr '24

03 Apr '24

FYI: There are many papers about Green Routing protocols. [2],[3] This paper [1] is an example from Prof Simon Romano which presents an "extension of the OSPF protocol to optimize the overall energy consumption of the network." The algorithm devised in this paper represents an engineering approach to the solution of the well known (though still open) issue of dynamic network topology adaptation to improve energy efficiency. For the GOSPF proposal there is running code available for people who want to play with it (https://wpage.unina.it/spromano/gospf/). It was based on the Quagga suite.It would need some tweaking in order to work with the current releases of the software. [1] GOSPF: An energy efficient implementation of the OSPF routing protocol https://arxiv.org/abs/2207.00035 (via E-impact mailing list https://www.ietf.org/mailman/listinfo/e-impact) + [2] Carbon-Aware Global Routing in Path-Aware Networks https://netsec.ethz.ch/publications/papers/green_routing2023.pdf [3] Exploring the Benefits of Carbon-Aware Routing : https://dl.acm.org/doi/10.1145/3629165 ^^^ this will be presented at RIPE88 !!
