Is it possible for gNB to detect whether a packet is video or non video?

Hello Experts.

Is it possible for gNB to detect any packet whether it is video or non video?

If yes how to measure buffering from gNB side?

While I know with probes and traces technique we will able to know but I want to know whether from gNB side with few counters is it possible to detect video and buffering ?

I think eNB, gNB can only distnguish TCP or UDP data type.

At gNB level we can differentiate at QFI level.

For example usually Voice traffic mapped to QFI-1.

Huawei is having technique to identify whether packet is pertaining to video or not.

But now question is: how gNB will calculate buffering?

Huawei will able to also tell you video throughput.
