In Huawei'sSD-WAN architecture, the following channels are defined:
Management Channel (Callout 1)
BetweeniMaster NCEandEdge devices.
Used for deviceregistration, configuration, and monitoring.
Encrypted with HTTPS.
Control Channel (Callout 2)
BetweenEdge devices and RR (Route Reflector).
Used forroute exchangeandcontrol signaling, typically overMPLS or Internet.
Data Channel (Callout 3)
BetweenEdge to Edge(e.g., HQ to branch).
Used for actualservice traffic transmission, carried overMPLS, Internet, or both.
Correct Mapping:
Management channel→ Callout1(from iMaster NCE to Edge)
Control channel→ Callout2(Edge to RR)
Data channel→ Callout3(Edge to Edge, over MPLS/Internet)
