Hello, We received this suggestion from a user present in NIX (Norway). I suppose we could configure an eBGP session with him on RRC0. What do you think?

RIS status report at RIPE51
by arife＠ripe.net 28 Sep '05

28 Sep '05

Hi guys, There will be 5-10 mins status update at Routing-WG, RIPE51. Presentation will roughly contain the following main points: - RIS: What is it? Contact info - Stats (if we can find some interesting stats) - RIS Performance study - Central server trouble keeping up with RRC - Analysis check for memory, CPU, and disk I/O - Result, disk is bottleneck - Solution: add disks -> even better, split DBs across servers - Getting away from central server design - Add more CPU and Disk. - What are user needs? - Fast applications - Less time lag - More data in DB - Feedback from users. Please let me know if something is missing. -- Arife Vural SED, RIPE NCC

riswhois request: reporting parent routes (fwd)
by Rene Wilhelm 08 Sep '05

08 Sep '05

Hi, Though it's nice to have an active user providing suggestions, I have the feeling his latest request would fall in the category "feature creep", making the program larger, more complex and the output harder to understand. However, before sending him a polite no-no, I'd like to ask how others in RIS feel about this. Should RISwhois embark on the trail of cross examining other routes (parents, daughters, siblings, ...) or not? -- Rene ---------- Forwarded message ---------- Message-ID: <431C426B.1060807(a)priv.onet.pl> From: Andrzej Adam Filip <anfi(a)poczta.onet.pl> Sender: ris-users-admin(a)ripe.net To: ris-users(a)ripe.net Date: Mon, 05 Sep 2005 15:04:43 +0200 Subject: riswhois: reporting parent routes Could riswhois generate statistics of "parent routes" for given route? [ parent, not ancestor] My goal is achieve better coverage of IP->AS mappings based on riswhois provided data. Unanimous AS reports (after ignoring default route) give very good starting point I would like to extend. For 65.54.160.0/19 I would like to know how many of 58 rispeers reporting the route reports also 65.52.0.0/14 route as belonging to AS8070. e.g. route: 65.54.160.0/19 origin: AS12076 [...] num-rispeers: 58 numrp-parent: 58 65.54.160.0/19 AS8070 P.S.

I'll keep it short: For over one year we have cheap IDE disks in an EMC-CX300. And our F810c (=NetApp at singel258) is no longer in use as backup-medium. Gerard.

Small is beautiful. Right, that's also what I had in mind; RISwhois provides a first quick overview, an overal looking glass on various RRC bgp tables. More complex queries, analysing updates, combining data from different prefixes, are out of scope, should be answered from RIS DB. -- Rene

Nice idea, but saving only 100GB is not much on a 1.6TB filesystem. And it is not a real solution to the diskspace-problem I was talking about. One extra concern: if you do so we will have 300GB of gzipped files on the backupserver, and 200GB of bzipped2 files. And as a result we do not have any space anymore on the backupserver. And that is exactly what I/ops is trying to solve. Pls do not do this on your own and consult ops before actually planning this! Gerard.

We can convert from gzip to bzip2. Few applications that use rawdata need to be changed to use bzip2. If you agree to use bzip2, I can proceed, and do the change.
