In Huawei's CloudFabric Solution, the iMaster NCE-Fabric SDN controller cluster separates network planes based on carried services to ensure scalability and security. Let's evaluate each option:
A). BGP microservice plane: This is not a standard plane in Huawei's SDN architecture. BGP is used in the underlay/overlay but not defined as a separate microservice plane for the controller.
FALSE.
B). Southbound service plane: This is true. The southbound plane carries configuration and control data to network devices (e.g., via NETCONF, BGP-EVPN), a critical service plane in SDN.
TRUE.
C). Northbound management plane: This is true. The northbound plane provides APIs for management applications and orchestration (e.g., OpenStack integration), handling service requests.
TRUE.
D). Internal communication plane: This is true. This plane facilitates communication between controller cluster nodes for synchronization and high availability. TRUE.
Thus, B (Southbound service plane), C (Northbound management plane), and D (Internal communication plane) are the network planes divided based on carried services.
