竞争窗口 meaning in Chinese
contention window
Examples
- In qg - dcf , qos grades include both delay grade and packet drop probability grade . qg - dcf supports the two grades by means of adjusting the minimum contention window and the maximum re - transmission limit
Qg一dcf提供两种qos分级服务:时延分级和丢组率分级，并且分别通过调节最小竞争窗口和最大重传次数来实现这两种分级服务。 - A markov model is used for calculation of dcf throughput . it is disclosed that the key parameters are the number of contending stations and the length of contention window . the maximum throughput and the best parameters are offered by theoretical analysis
对dcf部分，利用markov模型推导网络吞吐量性能，指出竞争站点数和竞争窗口长度是关键性能参数，从理论上给出最大吞吐量和最优参量值。 - A qos - support protocol , m - dcf , and its schedule model are proposed . by providing different contention window for different classes , the higher class frames the higher access probability . the simulation proves that m - dcf has better performance than dcf protocol on system throughput , discard ratio , frame discard ratio of higher classes , average access delay of different classes
提出了为不同等级帧提供不同竞争窗口的改进型dcf ： m - dcf协议，并给出了m - dcf的调度模型，通过采用不同的竞争窗口，为不同n西安电子科技大学博士学位论文:无线局域网和ip服务质量关键技术的研究的应用提供了不同的接入概率，保证了qos ;仿真结果证明了m一dcf在系统吞吐率、丢包率、高等级业务丢包率、不同等级业务的平均接入时延等方面都优于dcf协议。
