Decentralized Coded Caching With Distributed Storage Across Data and Parity Servers
Traditional single server based coded caching may face server saturation and service vulnerability problems. In this letter, we integrate decentralized coded caching with a multi-server architecture comprising both data and parity servers. For file distribution in this network, a method referred to as file stripping is adopted, and a novel file delivery scheme is proposed. Closed-form expressions for the total transmission rate achieved by this scheme are derived, considering all the operational servers along with the worst-case transmission rate amongst these servers. Additionally, a comparative analysis between the proposed scheme and the conventional decentralized coded caching scheme is presented. The simulation results demonstrate the viability of our proposed scheme.
