摘　　要：传统的网络架构在会话过程常发生网络中断从而无法提供足够的安全保障,针对现有的系统不能获取和组装通话记录,以及电话终端无法及时可靠地查询员工的通话记录的情况.提出了一种基于锚节点可靠路由协议的IMS电话呼叫分拣方法,通过流量捕捉模块将捕获的流量进行端口镜像,并解析SIP协议数据,其中流量当前IP报文通过预测链路生命期之后的候选中继节点的存在来识别更可靠的链路进行转发,以降低数据丢失的频率,提高员工的行政办公效率.将本文提出的优化的路由算法RRCP与GBSR和FMHR路由协议算法进行比较,通过网络仿真技术搭建网络通信模型,分析并验证上述路由优化协议在路由的故障数,丢包率,数据交付延时,平均跳数上显示出更好的性能,并在实际的监控系统测试中监控响应时长有效降低.The traditional network architecture often causes network interruption during the session process,which cannot provide sufficient security.The existing system cannot acquire and assemble the call record,and the telephone terminal cannot timely and reliably query the employee’s call record.An IMS telephone call sorting method based on the reliable routing protocol of the anchor node is proposed.The traffic capture module performs port mirroring on the captured traffic and parses the SIP protocol data.The current IP packet of the traffic passes the predicted link lifetime.The existence of candidate relay nodes to identify more reliable links for forwarding,to reduce the frequency of data loss,and improve the administrative efficiency of employees.The optimized routing algorithm RRCP proposed in this paper is compared with the traditional GRP algorithm.The network communication model is built by network simulation technology.The number of faults,packet loss rate,data delivery delay and average hop of the route optimization protocol are analyzed and verified.The number shows better performance.
