Network-coded storages for cloud computing

In this paper we propose a new infrastructure of storage overlay networks (SONs) that connect several distributed Internet nodes into an overlay network to provide in-network, aggregated storage. A SON node can encode, recode, and decode data on purpose. The SON improves information availability and security with erasure coding, and improves network efficiency by re-encoding received information. Two application cases of SONs to enhance present cloud storage are demonstrated. By jointly considering both storage and network issues, the proposed network-coded storage system can improve the availability, security and efficiency of contemporary cloud storage systems to a certain extent.
