【摘要】：内容分发网络是一种新型的网络构建方式,能为用户提供较好的网络访问速度和稳定性,但其复杂的网络设备使得能耗相对较大,因此,内容分发网络的节能及能耗评价是其重要的研究主题。针对内容分发网络的网络结构,提出一种睡眠-唤醒机制和动态速率调节机制相结合的内容分发网络节能策略,并运用随机Petri网对内容分发网络节能策略进行能耗分析。在随机Petri网建模的基础上应用模型化简和评价方法,通过分析随机Petri网模型各状态稳定概率得到系统平均能耗,并使用软件SPNP对节能机制加入前后的内容分发网络能耗进行对比分析。通过对比分析表明,该节能策略能很好地降低内容分发网络的平均能耗。
[Abstract]:Content distribution network is a new type of network construction, which can provide users with better network access speed and stability, but its complex network equipment makes the energy consumption is relatively large, so, The energy saving and energy consumption evaluation of content distribution network is an important research topic. According to the network structure of content distribution network, an energy saving strategy of content distribution network is proposed, which combines sleep-wake-up mechanism and dynamic rate regulation mechanism, and the energy consumption of content distribution network is analyzed by using random Petri net. On the basis of stochastic Petri net modeling, the model simplification and evaluation method are applied to obtain the average energy consumption of the system by analyzing the stability probability of each state of the stochastic Petri net model. The energy consumption of content distribution network before and after joining energy saving mechanism is analyzed by software SPNP. The comparison and analysis show that the energy saving strategy can reduce the average energy consumption of content distribution network.
