Restrictions around freeing memory with bgpdump_free_memory
by Rob Ballantyne 28 Nov '23

28 Nov '23

Hi, I’m running into memory access exceptions when using bgpdump_free_memory(). I’m collecting an interval worth of BGPDUMP_ENTRYs (1 minute worth) into buckets. After I have a bucket full I do a pairwise computation (that can take some time) of just this buckets data on a thread (from a pool) while the main thread moves onto the second bucket (and then starts up potentially another thread on the second bucket). … After the thread completes its summary statistics computation, it goes to call bgpdump_free_memory() on each of the BGPDUMP_ENTRY. I mutex lock so that only on thread will execute in bgpdump_free_memory() at a time. Are there restrictions (express or implied) on how to call bgpdump_free_memory() whether multi-threaded or not? BTW, if I run just a single thread it does seem to work just fine. Thanks, Rob

Two years of selective peering with RIS
by Michela Galante 23 Nov '23

23 Nov '23

Dear colleagues, We published an article on RIPE Labs where we talk about our RIS peering strategy of the last two years, what we've achieved so far, and why we've temporarily removed the peering form from our website: https://labs.ripe.net/author/emileaben/two-years-of-selective-peering-with-… We would love to hear your thoughts about it either here on this mailing list, in the Forum or live at RIPE 87. Best regards, Michela Galante RIPE NCC

Using libbgpdump - obtain aspath?
by Rob Ballantyne 07 Nov '23

07 Nov '23

Hello All, I’ve just started looking at libbgpdump for a project where I will be parsing MRT/BGP data. I’ve managed, following the example/advice I’ve seen, to get a basic loop running through an update file from the repository working. However, I don’t seem to be able to find the ASPATH component in the parsed data structure. I can see the type/subtype of the data block is BGPDUMP_TYPE_ZEBRA_BGP/BGPDUMP_SUBTYPE_ZEBRA_BGP_MESSAGE. I can also see that the BGPDUMP_BODY is a discriminated union based on these values. I can see that BGPDUMP_ENTRY.attr should probably contain an ASPATH but it doesn’t seem to be set ever. Should I be expecting the ASPATH to be set in this case? Should I be doing something different (calling some init function after discovering the BGPDUMP_BODY is of the right type?). Thanks! Rob

by Paul de Weerd 28 Sep '23

28 Sep '23

Dear colleagues, The quarterly plans for RIS can now be found at: https://www.ripe.net/support/documentation/quarterly-planning/ris In this quarter, we'll continue making improvements to RIS data through peering coordination and start working on open sourcing the RIS Live code. We hope that by providing these plans, we can better inform the community of the ongoing developments on RIS and get feedback on our work. If you have any input on these plans or suggestions for future work, please reach out to us. Kind regards, Paul de Weerd RIPE NCC

shutdown of rrc19 - NAPAfrica IX
by Marco Giuliani 08 Jun '23

08 Jun '23

Dear all, We are shutting down RIS collector rrc19, hosted at NAPAfrica IX, due to a hardware failure that could affect the integrity of the routing data collected. We are planning to replace the current hardware with a new server or a VM. Unfortunately, we have not yet found a feasible solution and do not have an estimate of when this will be done. We will inform you as soon as the new platform is available. Kind regards, Marco Giuliani RIPE NCC

New RIS MRT pipeline active
by Emile Aben 03 Apr '23

03 Apr '23

Dear colleagues, As of midnight today (3 April) the RIS MRT bview files ("table dumps") are created with a new pipeline, that results in more timely delivery of this data in smaller files. As a consequence of this change, a few gaps in RIS MRT bview files that were not created with the old pipeline in 2022, have also been filled. A list of these missing files is appended at the end of this email. kind regards, Emile Aben RIPE NCC Filled gaps for RIS MRT bview files: rrc13/2022.05/bview.20220524.1600.gz
