Low Latency 5G UPF Using Priority Based 5G Packet Classification
The ability to efficiently deliver on the 5G requirements (eMBB, mMTC, and URLLC) and implement a common NFV infrastructure with high levels of throughput, utilization, and determinism is a key enabler to deploy a virtualized UPF system for 5G and beyond.
One of the most stringent communication requirements is for timeliness and availability of a service where transmission occurs over a well-defined time interval with two main attributes of periodicity and determinism.
Periodicity means the transmission is repeated over a given time interval, whereas determinism refers to the delay between the transmission of a message and its reception at the target.
SK Telecom’s 5G Core network infrastructure for UPF provides such URLLC services depicted in the table and is a key research focus for this whitepaper by Intel which summarizes a collaboration between Intel and SK Telecom to demonstrate a 5G Standalone (SA) User Plane Function (UPF) capability based on 2nd generation Intel® Xeon® Scalable Processors and Intel® Ethernet 800 Series Network Adapters.
