As a key technology to reduce DNS resolution time,DNS performance optimization becomes a heated research issue.This paper proposes failed TTL-based renewal policy,which attains quicker query speed.Compared with traditional server of DNS,the accelerator of DNS is good at cache hit-rate,network traffic,CPU load and query-response time by the performance test of the concrete website,which achieves good performance.
