Research of QoS Monitor Algorithm for Space Based Real-time System
Zi Li · 2007
Space Based Network(SPN) is going to be an important part of the future military research. But if the current SPN architecture is short of QoS ensuring mechanism, it will lead to significant losses while system is overloaded. A QoS ensuring method for SPN which provides multi-class service is presented in this paper. It uses path response delay as the core measurement criterion of the architecture based on a continuous model of resource requirements. One class application is abstracted to a virtual path, and every component of SPN are glued tighter. And a set of dynamic adaptive QoS diagnosis algorithm is also presented. Experiments show that, although suffering severe overloading and burst, the user-perceived QoS can be ensured.
