摘要
IPSec在为用户通信提供安全性与机密性的同时不可避免地会带来网络性能的影响,特别会影响网络的服务质量(QoS)。网络性能受影响的程度与协议的数据结构占用的内存、完整性校验计算及加解密处理有关。在OPNET仿真环境中,设计一个与IP根进程联动的IPSec监测进程,以实现IPSec对具体业务影响程度的监测,为网络管理人员评估网络性能,升级软硬件设施,优化网络提供参考依据。
While IPSec is corresponding to provide a safety and secret for the customer and thus will inevitably bring the influence of network performance,this directly influences the QoS,and this phenomenon has something to do with data structures,integrality checking calculation and added decrypt and encrypt processing.In OPNET Modeler simulation environment,designed a dynamic IPSec monitor progress allied with IP root progress to carry out the influence of IPSec upon the concrete business monitor.It will provide the network manager evaluates network performance,updating the hardware design,optimizing network with a reference basis.
