Our next talk will be Friday June 11th with Edward Colone & Jem Aizen Guhit from the University of Michigan and they will be talking about "Benchmarking NetBASILISK: a Network Security Project for Science".  More info coming soon.

Greetings All;

The next CI Eng Lunch & Learn talk will occur Friday June 4th, 2021 @ 2pm ET.  The speakers will be Claudio Allocchio & Fabio Farina from GARR/GÉANT Project, and they will be talking about- "timemap: measuring latency and jitter on GEANT backbone (and beyond) ”.  Here is a quick abstract for the talk:  

Monitoring a network without knowing how the data flows is like reporting traffic conditions an an highway ignoring transit times and stops-and-go situations: just of little use if you want to predict how your journey will be. Transit time and stop-and-go translate into data packets latency and delivery time jitters on network and Timemap is the tool we developed to monitor them inside the GEANT backbone, a tool which can be / hopefully will be implemented also inside other national and international backbones. Services and Applications in strict need to know latency and jitter conditions to work correctly are out there and used daily, and some of them (like the very low latency high quality videoconferencing services in use in Performing Arts education and real time interactivity) need this monitoring to ensure a quick and reliable debugging when problems happen, too. We will show how we implemented the monitoring tool, directly talking to backbone routers to get the data, storing them and displaying and analyzing them; all using standard and open source well established components, with nearly zero "new developed software" to ensure an easy sustainability of the tool. Furthermore, since we started to collect historic data, we discovered interesting events which happen on the backbone, which were quite difficult to detect before, expanding our knowledge of the network itself. 

N.B. The Zoom number for 2021 is the same as 2020, connecting via computer preferred if you want to see materials, etc.  We ask that everyone *MUTE* on entry:
