Caracterização do Impacto de Incidentes de Aplicações em Redes e Usuários
Abstract
Characterization studies focused on network incidents provide a foundation for improving user experience, particularly in face of increasingly complex networks and the rise of technologies ever more dependent on the Internet. The causes for network incidents are diverse, including scheduled maintenance, routing issues, optical fiber cuts, and device failures. In this paper we seek to advance our understanding of the impact of network incidents. We study network incidents on large content providers from multiple perspectives, and characterize the impact of incidents on user and application behaviors. Our results indicate changes in the traffic profile of applications, such as an increase in the number of flows concurrent with a decrease in the overall traffic volume, as well as changes in user behavior, like the migration of demand from applications impacted by the incident to applications that were not.
