Programmable networking devices configured to perform various packet processing functions for packet filtration, control and user plane separation (CUPS), user plane function (UPF), pipeline processing, etc. Upon arrival of a user plane packet, a UPF performs a rapid lookup or hash table of the provisioned PDRs associated with a given PFCP session, arrange PDRs in decreasing order of precedence, and process the packet more efficiently than evaluating all PDRs.
