论文摘要
云数据库是云计算中的关键技术。云数据库的有效服务质量与通信技术密不可分，就像提高通信质量将减少票务系统中的并发现象一样。为了在视觉上观察通信对云数据库的影响，我们在准静态雷利褪色通道上提出了一个带有单服务器数据库的通信数据库（C-D）模型，该模型由三个部分组成：客户端源，通信系统和数据库系统。本文使用排队模型m/g/1 // k来对整个系统进行建模。在两种情况下分析了C-D模型：非线性和线性，这与SISO和MIMO的某些实例相对应。平均停留时间，平均交易数量和其他绩效特征的仿真结果基本上与理论结果一致，该结果验证了C-D模型的有效性。这些实验结果的比较还证明，沟通质量差的确会导致服务质量的降低。
Cloud database is the key technology in cloud computing. The effective and efficient service quality of the cloud database is inseparable from communication technology, just as improving communication quality will reduce the concurrency phenomenon in the ticketing system. In order to visually observe the impact of communication on the cloud database, we propose a Communication-Database (C-D) Model with a single-server database over the quasi-static Rayleigh fading channel, which consists of three parts: CLIENTS SOURCE, COMMUNICATION SYSTEM and DATABASE SYSTEM. This paper uses the queuing model, M/G/1//K, to model the whole system. The C-D Model is analyzed in two cases: nonlinearity and linearity, which correspond to some instances of SISO and MIMO. The simulation results of average staying time, average number of transactions and other performance characteristics are basically consistent with the theoretical results, which verifies the validity of the C-D Model. The comparison of these experimental results also proves that poor communication quality does lead to the reduction in the quality of service.
