Abrégé
A system causes a first user plane function (UPF) to transmit a first data packet to a domain name system (DNS) server and causes a second UPF to transmit a second data packet to the DNS server. The system determines a first latency value associated with the first data packet routing from the first UPF to the DNS server, and a second latency value associated with the second data packet routing from the second UPF to the DNS server. The system compares each of the first and second latency values with a threshold latency value. If it is determined that each of the first latency value and the second latency value is more than the threshold latency value, the system determines that the first latency value and the second latency value are caused by a network routing issue with respect to the DNS server and addresses the network routing issue.
