new poster “Measuring the Internet during Covid-19 to Evaluate Work-from-Home” at the NSF PREPARE-VO Workshop

Xiao Song presented the poster “Measuring the Internet during Covid-19 to Evaluate Work-from-Home (poster)” at the NSF PREPARE-VO Workshop on 2020-12-15. Xiao describes the poster in our video.

A case study network showing network changes as a result of work-from-home. Here we know ground truth and can see weekly work behavior (the groups of five bumps), followed by changes on the right in March when work-from-home begins.

There was no formal abstract, but this poster presents early results from examining Internet address changes to identify work-from-home resulting from Covid-19.

This work is part of the MINCEQ project, supported as an NSF CISE RAPID, NSF-2028279.

congratulations to Ryan Bogutz for his summer undergraduate internship

Ryan Bogutz completed his summer undergraduate research internship at ISI this summer, working with John Heidemann and Yuri Pradkin on his project “Identifying Interesting Outages”.

In this project, Ryan examined Internet Outage data from Trinocular, developing an outage report that summarized the most “interesting” outages each day. Yuri integrated this report into our outage website where is available as a left side panel.

We hope Ryan’s new report makes it easier to evaluate Internet outages on a given day, and we look forward to continue to work with Ryan on this topic.

Ryan visited USC/ISI in summer 2019 as part of the (ISI Research Experiences for Undergraduates. We thank Jelena Mirkovic (PI) for coordinating the second year of this great program, and NSF for support through award #1659886.

congratulations to Christopher Morales Ramos for his summer undergrad internship

We would to thank Christopher Morales Ramos for his summer internship at ANT, as part of the NSF-sponsored Research Experiences for Undergraduates (REU) Program at ISI in 2018:
Human Communication in a Connected World
. Christopher interned with us as part of his studies at the University of Puerto Rico where he is an undergraduate student in computer science.

Christopher’s project was improving the accuracy in estimating Round Trip Time (RTT) measurements from icmptrain our high-speed IPv4 prober, while minimizing the amount of traffic that was sent.  In addition to improving RTT estimates, his work can lead to better geolocation estimates.

His research at ISI was jointly advised by Yuri Pradkin and John Heidemann, as part of the ISI REU program directed by Jelena Mirkovic.
