The Science and Magic of Network Mapping and Measurement

On today's Day Two DevOps we dive into the complexities of network measurement and mapping with Dr. Nick Feamster, a professor at the University of Chicago and an expert in computer science and networking. Dr. Feamster shares his journey from building his first socket-based network while a teenager to applying machine learning in network performance. He discusses the technical challenges of data analysis and the founding of the Internet Equity Initiative, which aims to address internet access disparities. The discussion gets into data science, network measurement and mapping, and internet equity. | LISTEN NOW

Is OFDMA Worth It?

OFDMA is meant to reduce congestion by allowing APs to communicate simultaneously with multiple clients. On today's Heavy Wireless, guest Peter Mackenzie shares his OFDMA test results to see if it's worth using. When measured by throughput, the answer may be no. But when looking at efficiency, OFDMA may make a difference for latency-sensitive apps such as voice. Peter and Keith discuss how OFDMA works, and then dive into Peter's test results.| LISTEN NOW
