In Huawei CloudFabric solutions integrated with OpenStack, Neutron is the key component responsible for network service management and integration with external network controllers such as iMaster NCE-Fabric .
Neutron provides APIs for creating and managing network resources such as:
Networks (VXLAN/BD)
Subnets
Ports
Routers
iMaster NCE-Fabric integrates with Neutron via northbound APIs , allowing it to automatically translate cloud network requests into underlay and overlay configurations (e.g., VXLAN, EVPN, routing policies) on physical network devices.
Other components:
Nova (A) manages compute resources (VM lifecycle)
Keystone (B) handles authentication and identity services
Cinder (C) provides block storage services
These components do not directly interact with network controllers for fabric provisioning.
Huawei emphasizes tight integration between Neutron and iMaster NCE-Fabric to enable automated, policy-driven network deployment , which is essential for cloud data center operations.
Therefore, the correct answer is D (Neutron) .
