Product Architecture
| The system architecture of uSDM is based on the standard ETSI NFV architecture. The main functional components can be deployed as VNFs on the virtual infrastructure and managed by the cloud platform. The system architecture of uSDM is shown in the figure below: |
|
| Genew UnionCore uSDM is developed based on the idea of atom-level convergence, that means, not only the system is disaggregated into different modules, each module is a totally standalone Virtualized Network Function Component (VNFC) that could be deployed in a VM or Container, but also for both 2/3G, 4G and 5G signaling, are dealt within the unified Data Management (DM) module. |
