聚集流上的集中式网络效用最大化
Centralized Network Utility Maximization over Aggregate Flows
摘要:
我们研究了一个网络效用最大化(NUM)分解,其中的流率集是由源-目的地对分组。我们开发的单路径和多路径的情况下,涉及到一个简单的问题,只涉及每个源-目的地对的聚合速率的所有流量的任意NUM问题的定理。最优的聚合流然后在每对的组成流之间分配。这种分配对于$α$ -公平效用函数的情况是简单的。我们还展示了如何分解可以实现交替方向的乘法器(ADMM)算法。
英文摘要:
We study a network utility maximization (NUM) decomposition in which the set of flow rates is grouped by source-destination pairs. We develop theorems for both single-path and multipath cases, which relate an arbitrary NUM problem involving all flow rates to a simpler problem involving only the aggregate rates for each source-destination pair. The optimal aggregate flows are then apportioned among the constituent flows of each pair. This apportionment is simple for the case of $α$-fair utility functions. We also show how the decomposition can be implemented with the alternating direction method of multipliers (ADMM) algorithm.
