When an SDN controller cluster is deployed in Huawei CloudFabric Solution, which of the following network planes are divided based on carried services? (Select All that Apply)
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.References:Huawei CloudFabric Data Center Network Solution – SDN Architecture; HCIP-Data Center Network Training – Controller Planes.
