摘　　要：ENUM(Telephone NumberMapping,电话号码映射)是一种网络资源寻址方式,在IP数据网与PSTN电话网的融合中起着重要作用,它解决了不同通信方式之间的寻址问题。将因特网中的DNS技术用于电话网中的通信,有很多需要克服的难题,而性能和安全是最为关键的两大方面。ENUM的更新和查询是ENUM性能的主要问题,可以从网络的性能、使用的协议以及系统的配置等方面进行提高,负载均衡和选播是提高ENUM性能的新技术。对当前的ENUM实验系统进行了一系列的性能测试,测试结果说明其性能可以满足一般通信的需求。ENUM is one of the network resource addressing technologies. It plays an important role in the inter-infi/tration of Internet and PSTN（ Public Switched Telephone Network ）, for carrying out the addressing between different communication protocols. It has many problems to resolve while using DNS technology on PSTN, because DNS is usually used on the Internet. The performance and security are two serious aspects of ENUM. The ENUM＇s update and query are primary problems of the performance. It is influenced by networks, protocols and configurations of system. Load balance and anycast are the new techniques that can impove the performance. The ENUM system can sustain many normal communications.
