ENUM体系中NAPTR资源记录的研究

Research on NAPTR RR for ENUM System

下一代网络是一个融合的网络,要实现网络的融合,网络标识和寻址技术是至关重要的。ENUM就是作为电信网和互联网的寻址技术出现的。ENUM是DDDS算法的一个具体应用,采用DNS系统中的NAPTR类型存储算法规则库。介绍了ENUM体系的功能原理,就其功能范围进行了讨论。然后分析了DDDS算法,详细阐述了NAPTR资源记录,根据定义给出了更加严格的enumservice服务分类。

NGN is a convergence network. The Internet resource naming and addressing is very important to achieve the convergence. ENUM is introduced as the addressing technology between the telephone network and the Internet. It is a special application of DDDS algorithm and adopts the NAPTR type to store the rules in DNS. An introduction of the fundamental theory of ENUM system is provided, discussed the fundamental scope. The DDDS algorithm is analysed, specially expound the NAFFR RR, then puts forward a more strictly classification of the enumservice according the definition in RFCs.
