Os Seminários PESC têm como objetivo trazer palestras acessíveis a um público mais amplo, ministradas por pesquisadores e professores mais experientes (tanto do PESC como de instituições externas). Ao longo do ano, teremos temas e focos variados, podendo ser mais específicos ou mais abrangentes.
A apresentação e discussão de ideias novas e antigas de diferentes temas contribui de maneira fundamental para a formação e pesquisa desenvolvida por alunos e professores, sendo muitas vezes de interesse de um público mais amplo.
Os Seminários que são on-line ou híbridos ficam gravados no Canal do PESC no YouTube, que apresenta muitas outras gravações importantes sobre o que acontece no PESC.
NetMicroscope: Passive Measurements of Residential Internet Performance
Renata Cruz Teixeira, Senior Researcher, Inria Paris, França
27 de fevereiro (quarta), 11h
As access network speeds increase, the access link is less and less often the performance bottleneck for home users. In this context, performance tests a la "speed test" are rapidly becoming inadequate. First, they measure capacity to a dedicated server, not to real application servers. Second, they are becoming too disruptive as they must send enough probes to fill up the link. Instead of focusing on active measurements of access performance, our goal is to develop a mostly passive measurement system to monitor the performance of user applications. This talk will discuss our current system which measures video streaming quality completely passively. We will also discuss the lessons learned from deploying this system in 50 homes in the US and 10 homes in France.
Renata Teixeira is a senior researcher at Inria Paris and visiting scholar at Stanford University.
