2的幂次负载均衡策略下的轻流量行为:异构服务器的情况

Light traffic behavior under the power-of-two load balancing strategy: The case of heterogeneous servers

Ane Izagirre, Armand M. Makowski

摘要:

我们考虑了一个多服务器排队系统下的权力的2的政策与泊松作业到达,异构服务器和一般的作业需求分布,每个服务器下的先到先服务的政策,并没有缓冲区的限制。我们分析了该系统的性能,在轻交通的平均作业响应时间的前两个轻交通导数进行评估。这些表达式指出了几个有趣的结构特征与服务器的异质性在轻流量:对于不平等的能力,平均作业响应时间被认为是减少小值的到达率,和更多样化的服务器速度,更大的性能增益。通过有限的模拟评估这些理论研究结果。

英文摘要:

We consider a multi-server queueing system under the power-of-two policy with Poisson job arrivals, heterogeneous servers and a general job requirement distribution; each server operates under the first-come first-serve policy and there are no buffer constraints. We analyze the performance of this system in light traffic by evaluating the first two light traffic derivatives of the average job response time. These expressions point to several interesting structural features associated with server heterogeneity in light traffic: For unequal capacities, the average job response time is seen to decrease for small values of the arrival rate, and the more diverse the server speeds, the greater the gain in performance. These theoretical findings are assessed through limited simulations.
