Document worth reading: “Babel Storage: Uncoordinated Content Delivery from Multiple Coded Storage Systems”

In future content-centric networks, content material materials is acknowledged independently of its location. From an end-user’s perspective, explicit particular person storage applications dissolve proper right into a seemingly omnipresent structureless `storage fog’. Content should be delivered oblivious of the group topology, using numerous storage applications concurrently, and at minimal coordination overhead. Prior works have addressed the advantages of error correction coding for distributed storage and content material materials provide individually. This work takes a whole technique to highlighting the tradeoff between storage overhead and transmission overhead in uncoordinated content material materials provide from numerous coded storage applications. Our contribution is twofold. First, we characterize the tradeoff between storage and transmission overhead when all collaborating storage applications make use of the an identical code. Second, we current that the following stark inefficiencies could be prevented when storage applications use quite a few codes. What is further, such code selection just isn’t solely technically fascinating, nonetheless presumably could be the reality inside the increasingly heterogeneous networks of the long term. To this end, we current {that a} combination of Reed-Solomon, low-density parity-check and random linear group codes achieves close-to-optimal effectivity at minimal coordination and operational overhead.
