Abstract
A method for improving client subnet efficiency by equivalence class aggregation includes receiving a Domain Name System (DNS) query from a client, determining, based on predetermined class criteria, that the client is associated with an equivalency class, searching a cache associated with the equivalence class for an answer corresponding to the DNS query, and upon locating the answer, serving the answer to the client. Membership in equivalence classes can be adjusted, tuned, or otherwise modified based upon one or more criteria or rules. The adjustment of memberships may be a necessary step in response to changing network conditions. A membership in one or more equivalence classes can be adjusted based on determining changes in service (such as changes in bandwidth, quality of service, client location, and so forth), and/or based on detection of a modification to the network topology, and/or based on received input concerning performance.
