摘要

Systems and network devices configured for client-side domain name system (DNS) prioritization using time zone offset to select from configured list of DNS servers. A UE device (DNS client) may determine its current time zone, and query a locally stored domain name system (DNS) server list to select a regional DNS server based on its current time zone. The UE device may send DNS requests for resource addresses to the selected regional DNS server. In response, the UE device may receive DNS response messages that priorities resource addresses based on their geographic proximity to the current time zone of the UE device.

說明書

By using a local web server 107a, 107b, 107c, reductions in latency may be achieved. In addition, the performance and responsiveness of UE devices may be improved. For example, a DNS client computing device that is geo-located in New York may receive a response from the New York local web server 107a in 10 milliseconds, whereas the same response from a more distant web server (e.g., 107b or 107c) may take 20-30 milliseconds or longer.

FIG. 2 illustrates example components and operations in a system 200 configured to use DNS to resolve addresses in accordance with some embodiments. System 200 includes a DNS client 252 computing device (e.g., UE device 102, laptop computer 104, etc.) and a DNS server 254 computing device (e.g., DNS server 106, etc.).

In operation 202, the DNS server 254 may receive a DNS request for a resource address (e.g., hostname, etc.) from a DNS client 252. For example, the DNS server 254 receive a DNS request that includes the hostname or fully qualified domain name (FQDN) “product.company.com” in operation 202.
