摘要
论文提出了一种用于IPSec安全设备的QoS方案。该方案采用4个bit的标签来标志需要不同级别QoS服务的业务流,以快速为数据包分类;对排队队列采用循环调度算法,避免繁重的计算任务。仿真验证结果表明,该方案能够为关键业务提供恰当的QoS保障,使其能不受阻塞地通过IPSec安全设备。
This paper presents a type of QoS scheme used in IPSec security device,which adopts4-bit label to indicate different data streams with different requirement for QoS to classify packet rapidly.This scheme also adopts a circle scheduling algorithm to avoid heavy computation task.The simulation results show that this scheme can provide QoS guarantee for key tasks and transmit them through IPSec security device without blocking.
