Measuring and Analyzing Zoom Network Performance - A Passive Monitoring Approach

Learn how to effectively measure and analyze Zoom performance in production networks through this technical talk from NANOG. Discover techniques for analyzing Zoom's proprietary network protocol through packet-level examination, without requiring end-host cooperation. Explore systematic methods for identifying unencrypted packet fields, grouping streams into meetings, and distinguishing peer-to-peer sessions. Master the computation of critical performance metrics including media bit rates, frame sizes and rates, and latency and jitter. Follow along as Princeton University researcher Oliver Michel demonstrates these concepts using a 12-hour trace of campus network Zoom traffic, providing valuable insights for network operators involved in capacity planning, troubleshooting, and QoS policy implementation.
