Bandwidth-dependent selection of a packet routing node (e.g., user plane function (UPF) for 5G, packet data network gateway user plane function (PGW-U) for 4G) includes determining, for each of a plurality of packet routing nodes, a bandwidth capacity to an access network (e.g., a radio access node); receiving a request for a data traffic session; determining whether the data traffic session comprises a bandwidth priority; identifying a subset of the plurality of packet routing nodes having a higher bandwidth capacity than others of the plurality (e.g., the packet routing node having the highest capacity, or the top percentage); based on at least determining that the data traffic session comprises a bandwidth priority data traffic session, selecting a packet routing node for the data traffic session from the subset; and establishing the data traffic session through the selected packet routing node.
