基于模型和机器学习的Cache网络缓存和路由算法

Model and Machine Learning based Caching and Routing Algorithms for Cache-enabled Networks

Adita Kulkarni, Anand Seetharam

摘要:

网内高速缓存可能成为各种联网系统(例如,5G网络,LPWAN和IoT系统)。在本文中,我们比较和对比了基于模型的方法和机器学习方法,用于设计缓存和路由策略,以提高缓存网络性能(例如,延迟、命中率)。我们首先概述了基于模型的策略设计中使用的关键原则,并讨论了这些方法获得的分析结果和界限。通过对真实世界的痕迹和网络进行实验,我们确定了内容流行度偏度和请求流相关性之间的相互作用是影响缓存性能的重要因素。关于路由,我们表明,影响性能的主要因素是备用路径路由和内容搜索。然后,我们讨论了多种机器学习模型的适用性,特别是强化学习,深度学习,迁移学习和概率图形模型的缓存和路由问题。

英文摘要:

In-network caching is likely to become an integral part of various networked systems (e.g., 5G networks, LPWAN and IoT systems) in the near future. In this paper, we compare and contrast model-based and machine learning approaches for designing caching and routing strategies to improve cache network performance (e.g., delay, hit rate). We first outline the key principles used in the design of model-based strategies and discuss the analytical results and bounds obtained for these approaches. By conducting experiments on real-world traces and networks, we identify the interplay between content popularity skewness and request stream correlation as an important factor affecting cache performance. With respect to routing, we show that the main factors impacting performance are alternate path routing and content search. We then discuss the applicability of multiple machine learning models, specifically reinforcement learning, deep learning, transfer learning and probabilistic graphical models for the caching and routing problem.
