缓存即服务:面向服务提供商的小单元缓存机制设计

Caching as a Service: Small-cell Caching Mechanism Design for Service Providers

Zhiwen Hu, Zijie Zheng, Tao Wang, Lingyang Song, Xiaoming Li

摘要:

无线网络虚拟化已经被公认为通过解耦系统的功能并实现基础设施和频谱即服务来提高无线网络的灵活性的方式。最近的研究表明,缓存提供了一个更好的性能,以满足移动用户的内容请求。在本文中,我们提出了移动网络中的\emph{caching can be applied as a service},即,不同的服务提供商(SP)将它们的内容缓存在由移动网络运营商(MNO)拥有的无线设施的存储器中。具体而言,我们专注于\emph{small-cell networks}的场景,其中启用缓存的小小区基站(SBS)是缓存内容的设施。针对多个服务提供商之间的存储竞争问题,设计了一种基于多目标拍卖的存储竞争机制,该机制充分考虑了系统参数的时变性和内容替换的频繁性。仿真结果表明,我们的解决方案导致一个令人满意的结果。

英文摘要:

Wireless network virtualization has been well recognized as a way to improve the flexibility of wireless networks by decoupling the functionality of the system and implementing infrastructure and spectrum as services. Recent studies have shown that caching provides a better performance to serve the content requests from mobile users. In this paper, we propose that \emph{caching can be applied as a service} in mobile networks, i.e., different service providers (SPs) cache their contents in the storages of wireless facilities that owned by mobile network operators (MNOs). Specifically, we focus on the scenario of \emph{small-cell networks}, where cache-enabled small-cell base stations (SBSs) are the facilities to cache contents. To deal with the competition for storages among multiple SPs, we design a mechanism based on multi-object auctions, where the time-dependent feature of system parameters and the frequency of content replacement are both taken into account. Simulation results show that our solution leads to a satisfactory outcome.
