Abstract:

The current DNS had various performance and security problems, such as query delay, update latency, vulnerable to DoS attacks etc.Focuses on those problems, a novel, incremental deployable, compatible, and more effective domain name resolving service model was proposed.The service model was cloud sourcing, by using the cloud and its branch network worldwide to distribute DNS records, response DNS queries, and provide domain name resolved service.In this service model, the cloud edge servers function as local resolvers and authoritative nameservers, and authoritative DNS records were distributed to the edge servers, which directly responsed users’ DNS queries (if the quer not cached at local resolver, current DNS needed to access several nameservers in multi-level hierarchy).Compared with current domain name resolving services, the analysis and experiments prove that the service model show advantages in query latency, update latency, resiliency, and reliability etc.

Key words: domain name system, cloud sourcing, resolver, authoritative DNS record
