摘　　要：基于格式化转换字符串的ONS预解析规则是着眼于查询前的预解析阶段,而基于NAPTR记录的ONS解析规则在预解析阶段有所改进,移除了格式化转换字符串,侧重于ONS解析的应答格式。基于地址聚集的ONS解析规则改进在对上述两种规则进行扬长避短的同时,更侧重于ONS的网络拓扑结构。根据EPC的编码结构进行聚集,提出基于地址聚集的ONS解析规则,通过基于地址聚集的ONS解析实例分析。该方法一定程度上缓解了ONS服务器数据库的存储压力并减少了重复存储量,缓解了根ONS服务器的查询压力,同时网络拓扑结构能根据需要实现序列号级的查询。ONS pre -parsing rules,based on formatted string,is the pre -parsing stage aiming at fore -query.ONS parsing rules based on the NAPTR record focus on the analytic response format even though improvements are conducted in the preliminary phase to remove the formatted string.ONS parsing rules based on address gathered improves the rules mentioned above focusing on the network topology structure.Based on the EPC coding structure,this paper puts forward the address gathered ONS parsing rules and analysis of the ONS parse instance.It can also reduce the times to query database from the root ONS server.At the same time the network configuration can query the serial number in a particular situation.
