Highly available data-processing network functions for radio-based networks

A method, comprising:

• routing, by a tunnel host executed in a first computing device, network traffic on a radio-based network corresponding to a respective range of network addresses to a respective instantiation of a data-processing network function of a plurality of instantiations of the data-processing network function that process the network traffic before forwarding the network traffic to a plurality of user devices on the radio-based network, wherein the data-processing network function comprises a User Plane Function (UPF);
• receiving, by a route reflector executed in a second computing device, routing information from the plurality of instantiations of the data-processing network function;
• and
• forwarding, by the route reflector, the routing information to the tunnel host, the routing information comprising a first advertisement for a route for the respective range of network addresses to a first instantiation of the data-processing network function and a second advertisement for a backup route for the respective range of network addresses to a second instantiation of the data-processing network function.

A non-transitory computer-readable medium storing instructions that when executed in at least one computing device cause the at least one computing device to at least:

• route, by a tunnel host, network traffic on a radio-based network corresponding to a respective range of network addresses to a respective instantiation of a data-processing network function of a plurality of instantiations of the data-processing network function that process the network traffic before forwarding the network traffic to a plurality of user devices on the radio-based network, wherein the data-processing network function comprises a User Plane Function (UPF);
• and
• receive, by a route reflector, routing information from the plurality of instantiations of the data-processing network function;
• and
• forward, by a route reflector, the routing information to the tunnel host, the routing information comprising a first advertisement for a route for the respective range of network addresses to a first instantiation of the data-processing network function and a second advertisement for a backup route for the respective range of network addresses to a second instantiation of the data-processing network function.
