Using Related Domain Names to Improve DNS Performance

摘要: In this paper, we present a novel approach to exploit the relationships among domain names improve cache hit rate for local DNS server. Using these relationships, an authoritative server (ADNS) can piggyback resolutions future queries as part of response message initial query. The improves well reducing total and responses. is particularly attractive because it be implemented with no changes existing protocol. Trace-base simulations show more than 50% misses reduced in best case while straightforward policies, using frequency relevancy data ADNS, reduce by 25-40%. These percentages if focus policies on resource records smaller ATTLs. We also improved performance hybrid approaches that combine renewal-based approaches.
