The Huawei Controller allows next-generation networks to follow SDN principles
throughout the engineering process through the provision of network services,
policy orchestration, and management functionality via the Open Services
Gateway initiation (OSGi) framework and Representational State Transfer (REST)
API interface capabilities, that allow service applications to employ network
capabilities through their defined interfaces.
The result is that the controller enables the orchestration of network-wide
resources in support of application services.
