Abstract

Due to coronavirus pandemic, the traffic characteristics of computer networks, including the internet, registered a significant change. While the increase in internet traffic was evident, other networks, such as the LANs for corporations and research institutions, have showed a reduction in bandwidth consumption. However, this change in traffic profile is not limited to bandwidth consumption. There was also a change in the traffic type. In this work, we analyze this profile change under several different perspectives. In particular, an online opinion survey was carried out, aiming to analyze the profile of internet use from the users' point of view. The research focused on the intensity of internet use and the activity for which it was used, as well as on the user's perception of the connection stability. We also analyze the changes in the traffic patterns of Points-of-Presence of RNP (Rede Nacional de Ensino e Pesquisa), a network focused on higher education, research and innovation, and found out an increase of up to five times in the bandwidth consumption for videoconferencing applications, although the total bandwidth consumption has decreased.
