UDP-based Protocols (QUIC and RTP)
##################################

With UDP-based protocols it is not possible to implement a "generic" QoE measurement as with TCP. For this reason we have implemented QoE monitoring for:

- QUIC
- RTP


In particular:

- QUIC streams cn be monitored only when the `spin bit <https://blog.apnic.net/2018/05/11/explicit-passive-measurability-and-the-quic-spin-bit/>`_ is set.
- RTP streams are monitored calculaing a `pseudo-MOS <https://en.wikipedia.org/wiki/Mean_opinion_score>`_ as in `nProbe RTP plugin <https://www.ntop.org/guides/nprobe/plugins/rtp.html>`_.
