some thoughts on add-path and bmp at ripe/ris
by Randy Bush 25 Sep '25

25 Sep '25

i have some small thoughts on add-path and BMP in RIPE/RIS. this may hinder more than help, unfortunately. as a researcher, of course i would love a wider view into the AS graph and the views of as many ASs as possible. nom nom. but ... add-path, if not done very carefully, and documented in detail for each peer, will produce views i will not understand. it is analogous to not knowing what view a BGP peer gives RIS today. did it give me a full Nth view into peer X? is the path that of a peer, a customer, a provider? and add-path is worse because it prunes in configuration and vendor- dependent and otherwise unpredictable ways. and, as an operator if P is a RIS peer, and they give RIS BMP showing their input from their peers, upstreams, and customers, those peers, upstreams, and customers have not given thir consent to have their internals published! if they want to have RIS publish their internals, they would peer with RIS and choose what view they present. and, of course, the researcher does not know what view, peer, upstream, or customer P's BMP peer is giving them. same problem as above under add-path. randy

Call for presentations for MAT WG at RIPE86 in May
by Stephen Strowes 06 Apr '23

06 Apr '23

Hi all, RIPE86 is coming up fast: 22 -- 26 May! We are seeking your presentations for the next MAT WG session during that week. Presentations for the WG session are preferably 10-15min long. Please include in your proposal: * a title * a draft of your proposed presentation, even if just an outline * a paragraph describing the topic, and why the topic is of interest for the community. Interesting topics include (but are not limited to): recent measurement research which has an operational impact; recent operational work that may open avenues to research; projects, tools, or datasets that support either operations or research. Please submit your presentation proposal by Friday 28 April by emailing us at mat-wg-chairs at ripe.net. We will make our selections and post the agenda soon after. RIPE meetings are fully hybrid, and we encourage presentations from anywhere. Sessions are facilitated through meetecho. For our planning, we'd appreciate it if you can indicate whether you are likely to be online or on-site. Please ask if you have any questions regarding the setup on either side. Thanks! Cheers, Nina, Massimo, Stephen, as WG co-chairs

Re: [mat-wg] [address-policy-wg] 2023-02 New Policy Proposal (Minimum Size for IPv4 Temporary Assignments)
by Massimo Candela 07 Mar '23

07 Mar '23

Hi all, I added in cc the MAT mailing list, which is frequented by researchers. I believe that is the right audience for this proposal. @MAT: Support for this proposal should be expressed before this Friday (March 10). See proposal below. Reply by keeping both list. @Addres-policy: I support this proposal. ------- I also mention below a variation of this proposal, which could be it's own proposal/thread (suggestions welcome): There should be an easy way to do "temporary assignments" (which may or may not be the correct term in this case) to researchers/developers, starting from address space of a company which is "sponsoring" the research. The key part of what I would like to have is the possibility to provide somebody with access to LIR portal services but limited to a specific subset of my resources. In general, a company is not going to support a research/experiment by providing indiscriminate access to the LIR portal. Creating a new LIR or transferring prefixes is not a plausible solution in this context. Also, I believe this would remove the need for an approval procedure from the RIPE NCC side: (1) if the address space used is of a company, there is less need to validate the research project motivations; and (2) the company "sponsoring" is also the one responsible for the address space.

Improved timeliness of RIS dump files
by Emile Aben 07 Mar '23

07 Mar '23

Dear colleagues, We are planning to replace the pipeline that generates MRT dump files publicly available from the RIPE NCC. The new pipeline will have significantly less delay, and also some changes on the structure of the MRT file format [*]. Files in the newer format are available for testing here: https://www.ris.ripe.net/dumps-per-rrc-rest/prototype/ We have received feedback from MRT parser implementers that these files work fine for their parsers, but in case you haven't tested your MRT parser implementation, we ask you to test the new files before we make the switch. Our plan is to make this switch on 3 April 2023. After we make the switch the bview files available at our main location for downloading MRT files will be generated using the new pipeline and we will be able to produce these files in a more timely manner. Kind regards, Emile Aben RIPE NCC [*] These changes are documented here: https://ris.ripe.net/docs/40_Prototypes/15_per_rrc_dumps.html, but beware at this point we are only changing the files, not the frequency of dump files, nor putting the API in production. We did not receive feedback about these, but please let us know if you find them useful.
