摘要
研究了一种面向基于服务质量(Qo S)的多优先级消息队列调度算法的通用验证评估方法。从消息生成、时效性判断、发送策略评估和发送结果统计等方面建立了模型;并对某2.4 Kbps信道进行了系统仿真,统计得出了在该调度算法下的最优发送方案及消息丢包率。仿真结果表明文中设计的通用验证评估方法能够模拟调度算法所设计的消息发送规则和优先级翻转策略,并进一步以丢包率等Qo S参数为评价依据,证明对该队列调度算法验证评估的有效性。
The paper focuses on a kind of general validation and evaluation method for the multiple priority message queue scheduling algorithms based on the Qo S. The method builds the statistical models from the following aspects： message generation,timeliness,scheme evaluation and results statistics. The paper also provides the system simulation under the condition of 2. 4 Kbps channel bandwidth and comes to the conclusion of the optimal sending scheme and packet loss of the scheduling algorithm. The simulation results show that the general validation and evaluation method in this paper can realize the messages sending rules and flip priority strategies designed by the scheduling algorithms,and further based on Qo S parameters such as packet loss rate to demonstrate the effectiveness of assessment.
