WHITEPAPER: Low Latency UPF system for 5G and beyond

Low Latency 5G UPF Using Priority Based 5G Packet Classification

Whitepaper Low Latency UPF system for 5G and beyondThe 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.
