【摘要】：随着互联网技术的高速发展，日益增多的通讯业务对能量的消耗越来越大。如何降低网络能耗、提高系统效率已经成为研究者广泛关注的热点话题。论文针对以太网技术，提出基于周期性休眠的节能策略，并进行系统性能分析。首先，综合考虑以太网节能效率和系统响应性能，在IEEE802.3az的基础上，引入休眠延时、提前唤醒和分段计时机制，提出一种基于周期性休眠单速率传输的以太网节能策略。在离散时间范畴内建立一个带有休假延迟和N策略的多重休假排队模型，利用母函数方法进行模型解析，给出能量节省率和平均响应时间等性能指标的表达式。其次，考虑由数据传输的突发性特点以及由此造成的网络负载不均衡的现象，将ARL(Adaptive Rate Link)技术与LPI(Low Power Idle)技术相结合，提出一种基于周期性休眠双速率传输的以太网节能策略。建立一个单阈值可变服务率及N策略的多重休假排队模型，构造三维Markov链，给出系统的稳态分布。进一步推导出能量节省率和平均响应时间等性能指标的表达式。然后，针对两种节能策略分别进行数值实验和仿真实验，定量刻画休眠延迟计时器、休眠周期计时器、提前唤醒计数器、速率转变阈值及低传输速率等参数对系统性能的影响，并验证两种节能策略的有效性。最后，，基于实验数据中反映出的能量节省率和平均响应时间之间的折衷关系，通过构造目标函数，进行基于周期性休眠单速率传输的以太网节能策略和基于周期性休眠双速率传输的以太网节能策略的系统优化。
[Abstract]:With the rapid development of Internet technology, more and more communication services to the consumption of energy is more and more big. How to reduce the energy consumption of the network, improve the efficiency of the system has become a hot topic of researchers. The thesis focuses on the Ethernet technology, put forward the periodic sleep and energy saving strategy based on system performance analysis.
First of all, considering the efficiency and energy saving system of Ethernet response performance, on the basis of IEEE802.3az, introducing the sleep delay, wake early and split mechanism, put forward a kind of Ethernet energy saving strategy of periodic sleep single rate transmission. Based on the establishment of multiple vacations with a vacation delay and N strategy in discrete time domain queuing model the model analytically using the generating function method, given the energy saving rate and average response time. The expression of performance index
Secondly, considering the characteristics of burst data transmission and the resulting network load imbalance, ARL (Adaptive Rate Link) technology and LPI (Low Power Idle) technology, put forward a kind of Ethernet energy saving strategy of periodic sleep double rate transmission. Based on the establishment of a single variable threshold multiple vacation service the rate and the strategies of N queuing model, construct three-dimensional Markov chain, the steady state distribution system are deduced. The energy saving rate and average response time. The expression of performance index
Then, according to the two energy saving strategy conducted numerical experiments and simulation experiments, the quantitative characterization of the sleep delay timer, sleep cycle timer, wake early counter parameters affecting the rate of change threshold and low transmission rate on the performance of the system, and verify the validity of the two kinds of energy saving strategies.
Finally, reflect the experimental data in the energy saving ratio and the average response time based on the trade-off between, by constructing the objective function of energy saving strategies of Ethernet periodic sleep single rate transmission system based on Ethernet and Optimization Based on energy saving strategy of periodic sleep double rate transmission.
