Abstract

As a key technology to reduce DNS resolution time, DNS performance optimization becomes a heated issue in the field of research. This paper proposes a novel DNS accelerator which based on the invalid TTL renewal policy to attain the quicker query speed. Compared with traditional server of DNS, the accelerator of DNS has much more excellent function at cache hit-rate, network traffic, CPU load and query-response time by the performance test to the concrete website. The new DNS accelerator has a magnificent accelerating rate.
