Service Based Architecture

• Loosely coupled services, flexibilityin service oriented control plane

• Extensibility, service interact withlight weight service based APIs

• Modularity, in operational andmanagement independence

• Openness to 3rd parties viaNorthbound APIs

The networkarchitecture

shall be trulycloud-native!
