IWAN scenario based query

[vikrant.pandey@gmail.com]

Dear Technical Guys , please help me to understand better about IWAN, as mentioned in the above pic , i made a scenario where i use IWAN at branch router for switching traffic .

No i have some query as IWAN is a application part (North Bound) , i want to understand as according to this scenario , how in a single router IWAN as application and the Data Plane works , normally what picture in my mind for SD-WAN / SDN is a Northbound App. , A controller and a south bound protocol for interacting with devices .

Please help me to understand better .

How u guys put this query in TAC, as other routing issues are well discussed here , then there is no TAC, but as the sd-wan and sdn are the hot topic so u dont want to share any kind og knowledge for free so make this a TAC case, dear cisco u have different shades , when new tech. only money in mind so every KT is money based , old tech. is for free that cisco thinks , i believe .

I was hoping that someone would reply to your post.
I think you might be in wrong area.
APIC-EM 's northbound API usually refers to App control running on controllers.
Viptela, uses netconf with yang device model, to control southbound devices and configurations; not apps.
Maybe someone with knowledge can point you to right direction.
Good luck,
