【摘要】 讨论了网络服务质量技术的发展,分析了服务质量对IPSec安全设备的需求,设计了一种在IPSec安全设备中实施服务质量的体系结构,提出了对数据流采用两级分类和两级调度的机制,从而保障关键业务不在IPSec安全设备处被阻塞。该实施服务质量的体系结构将服务质量模块与IPSec模块有机地结合在一起,提供集成化的检测、控制和管理功能。更多还原

【Abstract】 The development of network quality of service (QoS )technologies is discussed. The QoS requirement for IPSec based security device is analyzed. Then the design of a type of architecture to implement QoS in IPSec based security device is given. Also this paper presents the two levels of classification and scheduling for data streams, which could prevent key tasks from being blocked at IPSec based security devices. This architecture combines the QoS and IPSec into a system, and provides detection, control and management together.更多还原
