Hi Balaji,
I'm currently working on UPF implementation [1] based on VPP that can be
used for 5G and 4G PGW/SGW deployments. The corresponding project that
implements the CP part of a SGW and PGW for that can be found at [2].
The UPF part so far has basic support for the Sx{a,b,c} reference points.
N3 is mostly identical to that, so 5G should almost work.
PDRs, FARs and simple URRs are supported.
The PDR support is somewhat hackish as the required ACL support needs DPDK
ACLs. It would great to have an ACL API within VPP that offers similar
functionality as the DPDK API. Unfortunaltly, the VPP ACL plugins are not
exposing enough functionality to be usable for PDRs.
Regards
Andreas
