on publishing interconnection parameters
by Dale W. Carder 21 Jul '21

21 Jul '21

On the call today the question was raised as to where one should publish, and correspondingly where one can find, route policy information for a given network. I believe it was Warrick that mentioned the (historical) utility of traceroute.org as an example. At least for commercial peers here in the US, the use of peeringdb.com is probably the default interface used today for peering coordination. I would claim that it would be of significant utility to R&E networks for coordination as well. From there one can find relevant information such as: - URL to a Peering Policy web page w/ additional details - URL links to looking glasses (if applicable) - additional details in the notes field For the more specific case of bgp community support, at present this is still free-form text that has to go somewhere, but it's not always clear where to look. To pick on my friend Warrick, you can find a good example at: https://www.peeringdb.com/net/393 Though perhaps in the notes field Warrick could say, "You can find supported bgp communities near the bottom of our magnificent 1,174 line aut-num record in RADB" Or for us at https://www.peeringdb.com/net/940 Perhaps we should add something to the tune of, "You can find our supported traffic engineering bgp communities at /dev/null, best of luck! But note for LHCONE VRF peers, we do support the mandatory knobs at https://twiki.cern.ch/twiki/bin/view/LHCONE/LhcOneVRF#BGP_communities" Dale

Summary from this morning, Next meeting APAN
by Schopf, Jennifer M 20 Jul '21

20 Jul '21

Hello Routing-WG members Thanks everyone who came to the meeting this morning. Our next meetings are: APAN Routing Working Group BOF, 9am August 3 Indonesia local time (10PM August 2, US Eastern time) 4 weeks from today, same time, walking through the examples (see notes below), 6am August 17, US Eastern time MANRS Talk by Steve Wallace, 8pm September 7, US Eastern time We meant to record today’s talk but that didn’t happen unfortunately. If there’s enough interest/need we can try to do another in the opposite time zone. The slides are available online here: https://docs.google.com/presentation/d/1x07cL8-o38sWHZd-RXSnZLinkj0t02IBXjp… We walked through 4 examples, although there’s a 5th in the slides (slides 17 and 18) for very strange routes between Singapore and New Zealand. These included unexpected the following unexpected routes: NIA (S. Korea) to Microsoft (Singapore) Nanyang Technological University (Singapore) to Education Bureau, Kaohsiung City Government (Taiwan) CERN (Geneva) to KISTI (S. Korea) KENET to SURFnet National University of Singapore to University Otago (New Zealand) We’d like to put together teams to start to address these, with the hopes of using these examples to talk about what infrastructure/documentation we need to address these more generally, and reviewing them at the mid August meeting. Please respond to any of the chairs if you want to be involved in any of these. If the co-chairs decide you’re needed, you may get looped in even if you don’t tell us. We’re hoping these teams will start working on these in the next week with the hopes of having something to report in 4 weeks. Likely these will also be discussed on the Slack channel – so don’t forget to watch there as well. Please get in touch with any questions or comments – see you in 2 weeks at APAN and then at our next regular meeting 2 weeks after that. -jennifer, on behalf of the Routing WG co-chairs ------------------------------------------------ Dr. Jennifer M.

Routing Working Group BOF at TNC Friday June 25th 14:00CEST.
by Addleman, Hans C 16 Jun '21

16 Jun '21

Greetings Routing Working Group, Next week on Friday June 25th at 14:00CEST during TNC (https://tnc21.geant.org/) we will be holding a Routing Working Group Birds of a Feather (BOF) session. Please find the abstract and connection information below. We hope to see you there! Hans Addleman Routing Working Group Co-Chair Identifying and Addressing R&E Routing Anomalies 14:00 - 15:30 CEST Adding or removing capacity from the global R&E network infrastructure can have unexpected routing results that are often difficult to detect and impossible to correct without coordination. For example, after changes in transatlantic capacity, we see significant volumes of traffic with both source and destination in Europe traversing exchange points in the US (traffic from CERN destined for universities in Europe routed via New York). Similarly, with other additions to transcontinental capacity, we see Asian traffic destined for Europe routed via the US (often crossing the Pacific twice), and also traffic with both endpoints in Africa routed via New York. We can identify these anomalous flows fairly easy with current and expanding tools, such as NetSage (http://portal.netsage.global). However, due to the number of different organizations along the international paths, it remains a challenge to bring the right people together to make adjustments that would potentially correct! the erroneous paths. This type of routing problem is prevalent, and we expect this issue is one many NRENs will need to address in order to maintain a robust, reliable, high-speed global R&E network. With new intercontinental links coming on-line over the past few years, and more planned for the near future, we believe the time is right for our community to come together to begin addressing this issue in a more coordinated way. This BOF will bring together R&E networking engineers in an open community discussion on how to approach this problem systematically.
