A Multi-Level Cache Framework for Remote Resource Access in Transparent Computing

With the increasing demand for high performance of remote resource access in transparent computing, there is a requirement to design a multi-level cache framework to alleviate the network latency. Existing cache frameworks in CPU and web systems cannot be applied simply because the remote resource access architecture needs to be extended to support multi-level cache, and the ways that resources are accessed in transparent computing require specific designs. In this article, we propose a multi-level cache framework for remote resource access in transparent computing. Based on the low latency feature of edge computing, we extend the remote resource access architecture to an architecture with multi-level caches by setting caches on the edge devices with low network latency. Then we design a hybrid multi-level cache hierarchy and make corresponding cache policies. Through a case study, we show the effectiveness of our design. Finally, we discuss several future research issues for deploying the proposed multi-level cache framework.
