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(More)
The P4 programming language [29, 16] has been recently proposed as a high-level language to program the forwarding plane of programmable packet processors, spanning the spectrum from software switches through FPGAs, NPUs and reconfigurable hardware switches. This paper presents a case study of using P4 to express the forwarding plane behavior of a(More)
