SYSTEMS AND METHODS FOR UTILIZATION OF ANYCAST TECHNIQUES IN A DNS ARCHITECTURE

摘要

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing multiple anycast addresses within a domain name system (DNS) architecture of a CDN. one or more DNS servers of the architecture may announce a plurality of anycast addresses for receiving DNS requests from requesting devices. The group of addresses may be dispersed (and/or announced by) the DNS servers of the architecture such that each server announces a subset of the available addresses. The number and identity of the subset of available anycast addresses utilized may vary from server to server of the DNS architecture and may be determined based on groups of servers, configurations of metros or gateways of the DNS architecture, or performance metrics of one or more servers.
