摘要
针对网络服务商提供视频服务部署成本过高问题,提出一种提供弹性服务的方法。首先,根据抽样原理建立不同点播时段请求到达率的预测模型;在此基础上应用流模型、微分方程稳定性理论和信号博弈原理建立了系统提供弹性服务的方法.该方法能够有效降低服务商的部署成本,提高系统的可扩展性和视频分发质量;最后通过仿真实验验证了提出方法的可行性.
In order to reduce the network deployment costs for service providers at the process of video demanding service,a flexible service-oriented method was proposed.According to the sampling theory,firstly a prediction model of the reaching rate of video demanding at different times was established.Based on this,a systemic flexible service-oriented method through employing fluid model,stability theory of differential equations and signaling game theory was provided.This method can effectively reduce deployment cost and increase system scalability and the quality of video distribution.Finally simulation experiment verifies the feasibility of this method.
