Abstract
A method comprises: at user plane functions (UPFs) of a network, creating a multicast group of the UPFs to enable inter-UPF communication between the UPFs in a multicast domain and, by each UPF: exchanging messages with peer UPFs of the UPFs in the multicast domain to learn peer attributes of the peer UPFs; reporting the peer attributes of the peer UPFs to a session management function (SMF) of the network; and at the SMF, selecting, for a data session, particular UPFs of the UPFs to be configured into a UPF chain of a data path for traffic from user equipment to a data network, based on the peer attributes of the peer UPFs as reported by the UPFs.
