Using DPDK APIs as the IF between UPF-C and UPF-U
UPF (User Plane Function) is the main data path element in 3gpp architecture for 5G.
Several carriers have announced their plans to place UPF in edge locations as part of their 5G deployment plans.
Carriers are looking for HW acceleration for UPF, as compute resources at edge locations are limited.
There’s a need to define a standard interface between the UPF application (UPF-C) and the SmartNICs (UPF-U).
We suggest using DPDK APIs as the interface between UPF-C and UPF-U.
The presentation will also list the missing APIs we need to add to DPDK for fully offloading UPF functionality.
