Framework comprisies of 4 layer architecture

OAM & Database Management

OAM & Functional Management

OAM & Control/Processing/Traffic Management

Signalling/Traffic Networking Management.

Each layer has distributed architecture and well define API to interact with each other.

All layers can be integrated into a single system or each layer acting as independent sub system and integrated together to form a system.
