Abstract
A cellular data communication network includes a gNodeB connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy snoops information and provides it to a BGP module that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF. The BGP module may program the first translation module with an SR policy associated with a binding SID that is bound to an interface to the gNodeB. The SR policy may invoke translation according to a function. The routing module may be programmed to embed GTP information in an SRH header that is used by the first translation module. BGP module may also distribute routing and VPN updates.
