Which component of the Prisma SD-WAN solution is responsible for the deep application identification (App-ID) and the generation of flow metrics (Network Transfer Time, Server Response Time) at the branch?
TheION Device Data Plane(the software running locally on the hardware appliance at the branch) is the component responsible for the heavy lifting of traffic analysis.
Edge Processing:Prisma SD-WAN uses an "Application-Defined" architecture. The ION device performsDeep Packet Inspection (DPI)on the first few packets of a flow to identify the application (e.g., distinguishing "Skype Video" from "Skype Chat").
Metric Calculation:The ION device timestamping engine calculates the performance metrics (RTT, NTT, SRT) in real-time as packets pass through its interfaces. It aggregates this metadata.
Role of Controller (B):The Controllercollectsandvisualizesthis data (Analytics), but it does notgenerateit. The Controller does not sit in the data path of the user traffic. If the ION relied on the controller for App-ID, latency would be unacceptably high. Therefore, all detection and metric generation happens locally on theION Device.
