为了满足下一代蜂窝网络(如6G)日益增长的需求，必须整合先进的网络技术。一方面，雾无线接入网(F-RAN)已被提出作为云无线接入网(C-RAN)的增强。另一方面，高效的网络体系结构，如命名数据网络(NDN)，已被公认为未来互联网的重要候选者。然而，F-RAN和NDN之间的相互作用值得进一步研究。在本文中，我们提出了一种支持NDN的F-RAN体系结构，该体系结构具有分布式网内缓存策略。通过仿真实验，验证了该缓存策略在网络资源利用率、缓存命中率、前端通道使用率等方面的优越性。
To meet the increasing demands of next-generation cellular networks (e.g., 6G), advanced networking technologies must be incorporated. On one hand, the Fog Radio Access Network (F-RAN), has been proposed as an enhancement to the Cloud Radio Access Network (C-RAN). On the other hand, efficient network architectures, such as Named Data Networking (NDN), have been recognized as prominent Future Internet candidates. Nevertheless, the interplay between F-RAN and NDN warrants further investigation. In this paper, we propose an NDN-enabled F-RAN architecture featuring a strategy for distributed in-network caching. Through a simulation study, we demonstrate the superiority of the proposed in-network caching strategy in comparison with baseline caching strategies in terms of network resource utilization, cache hits, and fronthaul channel usage.
