5G Shared Data Environment (SDE) – Critical enabler for 5G Service Based Architecture (SBA)

Download Report

Report Summary:

This report sponsored by Hewlett Packard Enterprise and Intel describes the requirement of 5G Service Based Architecture (SBA) for new high performance, scalable databases and distributed synchronized storage.

The new 5G Shared Data Environment (SDE) integrated via Service-Based Interfaces (SBIs) is becoming a critical requirement for implementation of cloud-native 5G Network Functions (NFs) and Service Functions (SFs) as lightweight high-performance microservices.

In this white paper, we describe an SDE architecture that not only allows for smooth migration from legacy networks and databases, without compromising the true 5G high-performance SDE solution, but also allows smooth interworking with 3G/4G HLR/HSS systems.

New 5G services will depend on the availability of high-performance SDE.
