Network coding has been recently applied in information-centric networking to improve its efficiency. When network coding is enabled at a content router, the router, in addition to caching content, may combine available data to produce coded data to send towards content consumers. Coded content, as has been previously shown, can improve content distribution efficiency over multiple delivery paths. Although every content router in information-centric networks is supposed to have caching, and anticipatedly, network coding facilities, the question is where should caching and network coding be carried out. It is beneficial to limit the number of network coding caches as caching consumes storage and network coding both consumes computational resource and incurs additional delay to the delivery process. Our proposal for a network coding cache placement answers such question to efficiently disseminate content in information-centric networks. |
