【摘要】：多媒体服务器的混合协议设计与实现的关键在与设计混合协议激振算法,通过激振算法设计提高多媒体混合服务器在饱和状态下的吞吐量。传统方法采用动态时分多址协议进行混合协议激振设计,当系统中节点众多、网络拓扑易变状态下,服务器的吞吐性能不好,提出一种基于CDMA协同调度的混合协议激振算法,并设计多媒体服务器,将大型多媒体联合服务器网络接收端和发送端数据的信息熵作为信道传递向量函数,在成功完成调度后,从节点开始进行正常收发工作,实现对时分多址(E-TDMA)协议设计。通过CDMA协同调度,在多媒体混合服务器的每一维度进行数据集分割,得到激振冲击响应。进行多媒体服务器总体模型构建与网络模型设计,在MAC层分别采用,三种协议进行系统调度和多媒体服务器的激振设计与仿真实现。仿真结果表明,该模型能有效提高多媒体服务器的吞吐性能,多媒体信道传输时间消耗最短,体现了算法较好的稳定性和鲁棒性能,对多媒体信息传输的保真性较好。
[Abstract]:The key of the hybrid protocol design and implementation of multimedia server is to design and design hybrid protocol excitation algorithm, which can improve the throughput of multimedia hybrid server in saturated state. The traditional method uses dynamic time-division multiple access protocol to design hybrid protocol excitation. When there are many nodes in the system and the network topology is variable, the performance of the server is poor, so a hybrid protocol excitation algorithm based on CDMA cooperative scheduling is proposed. The multimedia server is designed. The information entropy of the receiving and sending end of the large multimedia federated server network is taken as the channel transfer vector function. After the scheduling is completed successfully, the normal sending and receiving work starts from the node. Implementation of time division multiple access (E-TDMA) protocol design. Through CDMA collaborative scheduling, the data set is partitioned in each dimension of the multimedia hybrid server, and the shock response is obtained. The overall model of multimedia server and the design of network model are constructed. The three protocols are used in the MAC layer to schedule the system and to design and simulate the excitation of multimedia server. The simulation results show that the model can effectively improve the throughput performance of multimedia server, and the transmission time of multimedia channel is the shortest, which reflects the better stability and robustness of the algorithm, and the fidelity of multimedia information transmission is better.
