efficient diagnosis and troubleshooting of performance problems.</p><p>The Brazilian National Research and Educational Network (RNP) uses the perfSONAR open platform, an international standard for measuring IP network performance, and offers the academic community the e-Ciência MonIpê service, which allows the measurement of network performance and quality using distributed measurement spots. The results of the measurements are then stored and made available for queries.</p><p>Researchers from several academic institutions in Brazil are part of the Technical Committee for Network Monitoring (CT-Mon), coordinated by the RNP and whose main objective is to follow developments in monitoring, seek technological solutions and present recommendations to the RNP.</p><p>One of the purposes of the CT-Mon is to stimulate the production of knowledge on network monitoring and measurement. With that in mind, the group has selected 10 historically-relevant articles that helped shape and consolidate academic production in the area, influencing several other subsequent works. See them below:</p><p>Bolot presented a groundbreaking study that evaluated network performance using a simple and elegant analysis of packet delay, bandwidth, packet size and loss.</p><p>Bolot, J.-C.

In Proc. of the ACM pages 289–298, San Francisco, CA, USA.<br />https://doi.org/10.1145/167954.166265</p><p>The sequence of studies below showed, based on measurements, that local area network traffic, wide area network traffic and WWW traffic presented, respectively, self-similarity characteristics. They were instrumental to the understanding of traffic nature under different perspectives, signaling the need for new models for that traffic, and promoting the importance of network measurements for more realistic studies.</p><p>Leland, W.
