It takes a while to get to the point, but I am encouraged. Maybe we don't have to rebuild/reverse enginer a few 5g implementations from scratch.

In 5G, vAQM will be deployed as a network function by the UPF of the 5G core. It will be configured per PDU session, per SDF (Service Data Flow)/QoS flow – that is, the guaranteed bitrate (GBR) or nonGBR QoS flow. The non-GBR QoS flows of one PDU session will be aggregated and handled by one vAQM, whereas each GBR QoS flow will be allocated a vAQM with a dedicated virtual buffer. The Session Management Function (SMF) will configure vAQM and its virtual buffers for the QoS flows during the PDU session establishment/ modification phase. Configuration will occur when SMF provides the UPF with a QoS Enforcement Rule that contains information related to QoS enforcement of traffic including an SDF template (in other words, packet filter sets), the QoS-related information including GBR and maximum bitrate, and the corresponding packet marking information – in other words, the QoS Flow Identifier (QFI), the transport-level-packet-marking value. vAQM is self-learning, making it fully automated without any parametrization." -- Dave Täht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619 _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
