Abstract
A system and method for routing of 5G mobile data traffic along a routing path in an Internetwork Packet Exchange (IPX) network having requisite Quality of Service (QoS). A proxy is deployed in the IPX network to intercept Session Create request and response messages exchanges between the home network and the visited network. The routing platform extracts Single-Network Slice Selection Assistance Information (S-NSSAI) attribute and uses this attribute and the geographic locations of the visited network and the home network to select a routing path in the IPX network having requisite QoS for the network slice use case. The routing platform uses layer-3 routing technique to anchor User Plane Function (UPF) Proxies deployed at different routing paths in the IPX network. Alternately, the routing platform uses layer-2 routing technique, with Software-Defined Networking (SDN) controller and SDN-switches to route traffic via the selected routing path in the IPX network.
