I am trying to prioritize voice & video traffic over other types of traffic , i am using scapy to inspect and capture the traffic , i cant find a way to distinguish between those types. the field tos is always tos=0x0 .
i am doing this to send a set of rules to SDN edges using Ryu Controller

If you haven't changed the ToS value, then when you read traffic with it, it also won't be changed. – Ross Jacobs Apr 29 '20 at 20:07

Also, please don't ask the same question twice. You've already asked it [here](https://stackoverflow.com/questions/61491979/how-to-inspect-voice-video-traffic-flows-in-a-sdn-ruy-controller). – Ross Jacobs Apr 29 '20 at 20:21

i deleted the other questions sir , yes that's the point , i will not be asking the endpoints to change there Tos this isn't possible in the real world , that's why i am looking for an other way to differentiate traffic , DPI could help but how ? – alaeddinebenhassir Apr 29 '20 at 20:30

How should scapy differentiate between ToS values that are all the same? – Ross Jacobs Apr 29 '20 at 20:32
