  • in a network node including a plurality of message processors;

    receiving an inbound RADIUS message;

    determining that address resolution is required for the RADIUS message, wherein determining whether address resolution is required for the RADIUS message includes performing a lookup in an application routing table that maps a RADIUS message type of RADIUS Access Request requesting authentication challenge information to applications within the network node for processing the RADIUS message, wherein one of the applications mapped by the application routing table to the RADIUS message type of RADIUS Access Request is an address resolution application within the network node;

    in response to determining that address resolution is required for the RADIUS message, performing the address resolution using the address resolution application within the network node, wherein performing the address resolution includes mapping a non-routable identifier in the message to a routable address for a destination; and

    routing an outbound message to the destination using the routable address for the destination obtained from the address resolution application, wherein the outbound message comprises a RADIUS or Diameter message.
