【摘要】 针对当前域名系统，通过分析其域名解析的原理，指出其性能优化的方向。介绍了代理的有关概念和原理，并将代理技术应用于域名系统，提出智能移动代理在域名系统中的实现模型。对模型进行分析证明，应用代理技术的域名系统可以有效缩短域名解析时间，从而明显地提高域名系统的工作效率。更多还原

【Abstract】 Aiming at current domain name system (DNS), this paper analyzes its work procedure and domain name resolution principle and discusses the optimizing performance. Some concepts and principle of agent are introduced, technology of agent to DNS is applied and Intelligence Mobile Agent (IMA) model of DNS is proposed. Through analysis of this model, it is proved that the application of IMA to DNS can reduce the resolution time. This model can obviously increase the efficiency of DNS.更多还原
