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

Dear MAT friends, During LACNIC 40 (Fortaleza, Brazil) [1], there will be a session of the Internet Measurements Working Group (IMWG) on Friday 6 October 2023. The IMWG is a new working group with similar goals of MAT but focuses on creating bridges among academia, researchers, and network operators in the LACNIC region. The mailing list of the IMWG is imwg(a)listas.nog.lat Since this year the LACNIC and RIPE events will be more than a month apart, I'm asking here help in creating the agenda for IMWG. The IMWG is looking for presentations on Internet measurements, network data collection, data analysis and tools. Please, submit your presentation proposal by September 22 by sending an email at imwg-owner(a)listas.nog.lat We prefer talks of 15min. Include in your email a title, a draft of the presentation, a paragraph describing what you will talk about and why the topic is of interest for the community, and if you are planning to present in person or remotely. Feel free to share this message on other channels. Thanks! Ciao, Massimo [1] https://lacnic40.lacnic.net/
