VPP: sFlow Monitoring

This talk describes work on an sFlow plugin for VPP (Vector Packet Processing), a popular userspace dataplane, enabling statistical packet sampling at very high rates using the sFlow protocol. In addition to standard packet sampling, dropped packets can also be observed to provide deeper insights into dataplane performance. A live integration demonstration across sflowtool, ntopng and Akvorado illustrates what actionable network visibility looks like in practice.
