Abstract
A top level domain name system (DNS) server receives a DNS query from a local DNS resolver, the DNS query requesting a network address corresponding to a domain name. The top level DNS server reflects the local DNS resolver to a reflector DNS server. The reflector DNS server reflects the local DNS resolver to a collector DNS server, which in turn returns the network address to the local DNS resolver. The reflector DNS server and collector DNS server are both in the same data center, and one or more network performance measurements for communications between the local DNS resolver and the data center are determined based on the communications between the local DNS resolver and both the reflector DNS server and the collector DNS server.
