Abstract
A cellular data communication network includes a BBU 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 intercepts control packets of the UPF. Information snooped by the PFCP proxy is provided to a routing/SDN controller that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF.
