The NFs that we selected for the validated 5G Core solution provide a routing and policy framework to build a multivendor 5G network with the resiliency and scalability that is needed for 5G use cases.
This Dell Validated Design solution can integrate additional NFs from third-party vendors (AMF, SMF, UPF, AUSF, UDM) and from Oracle (SEPP, NEF) to provide a complete 5G Core solution and support new use cases.
Oracle 5G NFs provide standard interfaces that are aligned with Rel-15 and Rel-16 procedures. For our design validation, we deployed the NFs in live networks and integrated them with other NFs from all major vendors in the market.
We tested multiple use case and end-to-end procedures using NF simulators such as AMF or SMF to generate HTTP requests according to 3GPP standards.
The solution can scale within a single site or in geo-redundant scenarios across two or more sites.
A single network site may include multiple instances of the same NF type, such as AMF, SMF, and PCF. The SCP can optimize the traffic in the network, ensuring load distribution and resiliency.
All Oracle NFs support geo-redundant deployments across two or more sites. NFs are made of stateless microservices that manage the SBI interfaces and the application logic of each NF, while session states are stored in a separated DBTier layer that is built on MySQL. The DBTier uses MySQL CGE to provide disaster recovery capabilities across two, three, or four sites.
The Oracle NFs in each site use a common DBTier, which replicates data on the DBTier cluster in the other site. If an NF in one site (or even the whole site) becomes unavailable, the corresponding NF in the other site can take over the subscriber sessions of the failed NF because the session data is replicated on the DBTier in the other site. The NFs must be properly dimensioned to manage extra traffic in case the other site becomes unavailable.
