摘　　要：鉴于标签转发表在PTN技术中的重要性,提出在网络邻居节点存储备份标签转发表信息的方法,实现网络受损条件下替换节点业务转发能力的快速恢复。同时,运用数据交织、加密、流量控制等技术,保证网络节点标签转发表信息的安全保密存储,控制关键备份信息的知悉范围;并降低信息存储过程产生的数据流量对网络正常业务的影响。For the importance of label forwarding tables in PTN network,a method of traffic forwarding tables information stored on neighbor nodes in the same network is proposed which will help replaced node to provide data path traffic forwarding ability quickly when damage occurred. At the same time,the technology such as data interleaving,encryption and traffic controlling are used to guarantee the secure store of the label forwarding tables,control the knowing range of key backup information,and reduce the influence of traffic produced by Information storing process on the network normal operation.
