摘要:

流量工程(TE)是互联网的基本构建块。在本文中,我们分析了现代机器学习(ML)方法是否可以用于TE优化。我们通过ML的最新技术水平和TE的最新技术水平之间的比较分析来解决这个悬而未决的问题。为此,我们首先为TE提供了一种新型的分布式系统,该系统利用了ML的最新进展。我们的系统实现了一种新的架构,结合多智能体强化学习(MARL)和图神经网络(GNN),以尽量减少网络拥塞。在我们的评估中,我们将我们的MARL+GNN系统与DEFO进行了比较,DEFO是一种基于约束编程的网络优化器,代表了TE的最新技术水平。我们的实验结果表明,所提出的MARL+GNN解决方案实现了等效的性能DEFO在各种各样的网络场景,包括三个现实世界的网络拓扑结构。同时,我们证明了MARL+GNN可以显著减少执行时间(从DEFO的几分钟到我们的解决方案的几秒钟)。

英文摘要:

Traffic Engineering (TE) is a basic building block of the Internet. In this paper, we analyze whether modern Machine Learning (ML) methods are ready to be used for TE optimization. We address this open question through a comparative analysis between the state of the art in ML and the state of the art in TE. To this end, we first present a novel distributed system for TE that leverages the latest advancements in ML. Our system implements a novel architecture that combines Multi-Agent Reinforcement Learning (MARL) and Graph Neural Networks (GNN) to minimize network congestion. In our evaluation, we compare our MARL+GNN system with DEFO, a network optimizer based on Constraint Programming that represents the state of the art in TE. Our experimental results show that the proposed MARL+GNN solution achieves equivalent performance to DEFO in a wide variety of network scenarios including three real-world network topologies. At the same time, we show that MARL+GNN can achieve significant reductions in execution time (from the scale of minutes with DEFO to a few seconds with our solution).
