In-Band Network Telemetry @ AmLight demo at Supercomputing Conference SC21
Network Research Exhibition @ RENCI’s Virtual Booth (sc.renci.org)
The goal of this demo is to showcase the benefits and challenges of deploying In-band Network Telemetry (INT) in a long-haul production network. The INT solution was built leveraging off-the-shelf P4 white box switches with the Barefoot Tofino chip, NoviFlow NoviWare Network Operating System, and a telemetry data gathering solution developed by FIU called INT Collector. The INT switches deployed at AmLight have 32x100G ports, support P4, and flexible forwarding pipelines, and were expanded to support INT for TCP and UDP flows.
