The SD-Core™ project is a 4G/5G disaggregated mobile core optimized for public cloud deployment. It exposes standard 3GPP interfaces enabling use of SD-Core as a conventional mobile core. It is also available pre-integrated with an adapter (part of the Aether ROC subsystem) for those deploying it as a mobile core as-a-service solution.

SD-Core is an integral component of Aether, ONF’s 5G Connected Edge platform for private mobile connectivity and edge cloud services. 

SD-Core Architecture

SD-Core leverages control plane components of the Free5GC project and the ONF OMEC project, building on both of these upstream open source projects by adding cloud native capabilities for scaling, resiliency and multi-cloud agility.
Three User Plane Function (UPF) implementations are designed to be deployed throughout the edge of the network with each optimized for specific use cases:

Maximum Performance: P4-UPF
Software-based dual-mode 4G/5G UPF, optimized for Intel® Xeon® using DPDK, supporting any I/O option (SR-IOV, AF_PACKET, AF_XDP), and scalable to 100 Gbps on Intel Ethernet Network Adapter E810 with Dynamic Device Personalization (DDP).

High throughput on Intel servers: DPDK-UPF
Software-based dual-mode 4G/5G UPF, optimized for Intel® Xeon® using DPDK, supporting any I/O option (SR-IOV, AF_PACKET, AF_XDP), and scalable to 100 Gbps on Intel Ethernet Network Adapter E810 with Dynamic Device Personalization (DDP).

Maximum flexibility to run on any cloud: Flex-UPF
Software-based dual-mode 4G/5G UPF UPF for campus and multi-cloud, implemented with eBPF and optimized with AF_XDP to make it suitable to run on any variety of CPU (available later this year).

SD-Core is an integral component of Aether, ONF’s 5G Connected Edge platform for private mobile connectivity and edge cloud services.
