P4 In-Band Telemetry (INT) for Latency-aware VNF in Metro Networks
Filippo Cugini, P. Gunning, Francesco Paolucci, P. Castoldi, A. Lord · 2019
A first demonstration of P4-based virtual network function (VNF) for latency-critical services is presented. The VNF exploits P4 In-band telemetry to dynamically enforce per-packet QoS priority according to cumulated latency performance.
