The datasets from Internet Service Providers, Internet Exchange Points, and academic networks, primarily in Europe, provide a unique view on the changes of Internet traffic due to pandemic and the lockdown that forced hundreds of millions of citizens to stay and work from home. The analysis shows that the increase of Internet traffic was about 15-20 \% within a couple of weeks, an increase that is typically spread over multiple months under typical operation. However, traffic during peak hours does not increase by more than 5 \%. The increase was noticeably higher for specific applications, e.g., remote work applications, teleconferencing, video on demand; in some cases up to 200 \%. However, overall, the Internet reacted well to these unprecedented times.}, language = {en} } @misc{FeldmannGasserLichtblauetal., author = {Feldmann, Anja and Gasser, Oliver and Lichtblau, Franziska and Pujol, Enric and Poese, Ingmar and Dietzel, Christoph and Wagner, Daniel and Wichtlhuber, Matthias and Tapiador, Juan and Vallina-Rodriguez, Narseo and Hohlfeld, Oliver and Smaragdakis, Georgios}, title = {A Year in Lockdown: How the Waves of COVID-19 Impact Internet Traffic}, series = {Communications of the ACM}, volume = {64}, journal = {Communications of the ACM}, number = {7}, issn = {1557-7317}, doi = {10.1145/3465212}, pages = {9}, language = {en} } @misc{WagnerKoppWichtlhuberetal., author = {Wagner, Daniel and Kopp, Daniel and Wichtlhuber, Matthias and Dietzel, Christoph and Hohlfeld, Oliver and Smaragdakis, Georgios and Feldmann, Anja}, title = {United We Stand: Collaborative Detection and Mitigation of Amplification DDoS Attacks at Scale}, series = {ACM CCS 2021 - November 15-19, Virtual Conference}, journal = {ACM CCS 2021 - November 15-19, Virtual Conference}, doi = {10.1145/3460120.3485385}, language = {en} }
