Methods, systems, and computer readable media for actively discovering and tracking addresses associated with 5G and non-5G service endpoints

Abstract:

A method for discovering and tracking addresses associated with producer network function (NF) service endpoints includes receiving a first domain name system (DNS) resolution request from a requesting node. The method further includes querying a DNS server using a fully qualified domain name (FQDN) extracted from the first DNS resolution request. The method further includes receiving a first response from the DNS server, the first response including an associated with a producer NF service endpoint associated with the FQDN and storing the address associated with the producer NF service endpoint in a database. The method further includes communicating the address associated with the producer NF service endpoint to the requesting node. The method further includes monitoring the FQDN for changes in address associated with the FQDN. The method further includes notifying the requesting node of the changes in address associated with the FQDN.
