Read on RIPE Labs: Network Complexity and How to Deal with it
by Mirjam Kuehne 01 Mar '11

01 Mar '11

[apologies for duplicates] Dear colleagues, Prompted by a panel discussion at the RIPE 61 Meeting, this article by Michael Behringer describes the most significant implications of network complexity and suggests ways to deal with it: http://labs.ripe.net/Members/mbehring/network-complexity-and-how-to-deal-wi… This is a topic that requires more work and a lot of input from network operators. We hope you will help to advance this subject. Kind Regards, Mirjam Kuehne RIPE NCC

Dear colleagues, Following-up from his presentation at RIPE 61 in Rome, Claudio Squarcella published an article on RIPE Labs: http://labs.ripe.net/Members/csquarce/caidagram-visualization-tool It describes Caidragam, a new tool to visualise geographically annotated Internet measurements, for instance topology, address allocation, DNS and economical data. You can also find a link to the actual tool and a live demo at the end of the article. Kind Regards, Mirjam Kuehne RIPE NCC

Comments on RIPEstat
by Richard L. Barnes 24 Feb '11

24 Feb '11

Just wanted to start a thread on this list where people could contribute thoughts about RIPEstat. To get things started, here are a few things that occurred to me during the call this morning: -- Time zooming is awesome. I haven't yet looked to see if this zooms the linked raw data as well; if it doesn't it should. -- YAML might not be everyone's preferred format for data. It might be nice for the "raw data" link to go to a page that displays the data (e.g., as a table) with links at the top: "Download as: YAML, CSV, JSON, XML, ..." -- The AJAX loading is good, but there's no "busy indicator" that tells me that the request is outstanding, vs. the blocks simply not loading. -- The idea of country indexes (http://stat.ripe.net/country/dk) seems like it could be handy and not too difficult to implement. It would probably be accurate enough to get the geolocation from the delegation files and call up information for those resources. -- +1 on the addition of a methodology link. Again, would be useful, especially for first-time or occasional users, and not too hard to implement (just some static text). Stylistically speaking, it's probably a small enough bit of text that it could be done as an AJAX popup/overlay. Thanks for keeping the community involved in this project, --Richard

Three Case Studies on the Egyptian Disconnection
by Mirjam Kuehne 15 Feb '11

15 Feb '11

[apologies for duplicates] Dear colleagues, Claudio Squarcella from Roma Tre University presents three analyses related to the recent events in Egypt, proving interesting behavior in relation to the observed disconnection. He used tools like BGPlay and iBGPlay, developed for the visualisation of BGP dynamics. See his findings on RIPE Labs: http://labs.ripe.net/Members/csquarce/three-case-studies-egyptian-disconnec… Kind Regards, Mirjam Kuehne RIPE NCC

Another view of Egypt falling off the net
by John S. Quarterman 03 Feb '11

03 Feb '11

This view shows paths to six selected nodes inside Egypt, before and during the disconnection: https://www.internetperils.com/perilwatch/20110127.php The timing matches what RIPE saw, and the order matches what Renesys saw. This view is not based on BGP routes; it is derived from regular probes (every 15 minutes) showing hops along the way, and thus shows detail of paths from several cameras outside Egypt to the selected destinations. None of those destinations have reappeared yet. -jsq
