Adaptive routing of content requests using multiple anycast addresses |
摘要 |
A system includes a plurality of cache servers and a domain name server. Each of the cache servers is configured to respond to a content request. The plurality of cache servers is divided into a plurality of subsets and configured to respond to an anycast address for each subset to which the cache server belongs. The domain name server is configured to receive a request from a requester for a cache server address, identify an anycast address for a largest available subset, and provide the anycast address of the largest available subset to the requester.
