QOS in SDWAN

Hello Everyone,

The query is about enabling QOS for the Voice and Video in SD-WAN.

 

Do we need the QOS enabled on the provider end as well ? (on transport side)

As per my understanding the traffic will be tunneled under ipsec, and being encrypted traffic, do we really need the qos enabled on PE?

Thanks in advance.

QoS is not reliant on the ISP or this case, the PE. 

Your QoS parameters will move traffic based on your thresholds, which you control 100%. 

Please elaborate on what type of QoS you're looking to implement so we can all provide a better explanation, if possible.

Yes, absolutely for critical time sensitive traffic, and best practice for any other traffic. QoS markings get copied from the edge devices into the IPSec header so that the QoS policy marking information is available to the ISP and your ISP's infrastructure needs to recognize these markings in order to provide the correct scheduling.

 

Its described here:
