In-band Network Telemetry (INT) is a new abstraction that allows data packets to query switch-internal state such as queue size, link utilization, and queuing latency. We prototype INT in the recently proposed P4 language using a software switch as the implementation platform. We then show how INT can be used to diagnose performance problems such as intermittent latency spikes. Instructions to replicate our demo are available at http://git.io/sosr15-int-demo
