Abstract

With the deployment of caches, cache consistency has become a serious concern. Strong cache consistency is defined as the model in which no stale copy of a modified original will be returned to clients, whereas weak cache consistency is the model in which a stale copy might be returned to clients. Currently, DNS only supports weak cache consistency by using the Time-to-Live (TTL) mechanism we propose a proactive DNS cache update protocol (DNScup), working as middleware to maintain strong cache consistency among DNS name servers and improve the responsiveness of DNSbased service redirection.
