by Mirjam Kuehne 21 Mar '11

[apologies for duplicates] Dear colleagues, In an earlier article on RIPE Labs, we showed that a large percentage of 6to4 connections fail. In this new article by Emile Aben, we look at why these connections fail and what can be done about this: http://labs.ripe.net/Members/emileaben/6to4-why-is-it-so-bad Kind Regards, Mirjam Kuehne RIPE NCC

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

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
