摘要:

计算机网络的性能依赖于带宽如何在不同的流之间共享。公平的资源分配是一个具有挑战性的问题,特别是当流量随着时间的推移而变化时。为了解决这个问题,带宽共享技术,快速反应的流量波动的兴趣,特别是在大规模的设置与数百个节点和数千个流。在这种情况下,我们提出了一种分布式算法的基础上交替方向乘法(ADMM),解决了多路径公平资源分配问题,在分布式SDN控制架构。我们的ADMM为基础的算法不断产生一系列的资源分配解决方案收敛到公平分配,同时始终保持可行的,标准的原始-对偶分解方法往往缺乏的属性。由于所有计算机密集型操作的分布,我们证明了我们可以大规模处理大型实例。

英文摘要:

The performance of computer networks relies on how bandwidth is shared among different flows. Fair resource allocation is a challenging problem particularly when the flows evolve over time. To address this issue, bandwidth sharing techniques that quickly react to the traffic fluctuations are of interest, especially in large scale settings with hundreds of nodes and thousands of flows. In this context, we propose a distributed algorithm based on the Alternating Direction Method of Multipliers (ADMM) that tackles the multi-path fair resource allocation problem in a distributed SDN control architecture. Our ADMM-based algorithm continuously generates a sequence of resource allocation solutions converging to the fair allocation while always remaining feasible, a property that standard primal-dual decomposition methods often lack. Thanks to the distribution of all computer intensive operations, we demonstrate that we can handle large instances at scale.
